Pest Control FAQ for Santa Clarita Homeowners
We have been handling pest and termite problems in the Santa Clarita Valley since 1998. Below are the questions our office gets asked most, answered plainly. If yours is not here, call us at (661) 765-8938 and we will talk it through with you.
-
About CVA and How Our Service Works
-
What Areas Do You Serve?
Our general pest control service, both recurring plans and one-time visits, stays within the Santa Clarita Valley. That includes Valencia, Newhall, Saugus, Canyon Country, Castaic, Stevenson Ranch, Sand Canyon, Val Verde, and Agua Dulce. Our termite and wood-destroying organism work travels further, covering most of Los Angeles and Ventura counties.
-
Are you licensed?
Yes. CVA Exterminators, Inc. is licensed by the California Structural Pest Control Board, Company Registration #PR4456. Our inspections are performed by licensed inspectors rather than commissioned salespeople, so if an inspection turns up nothing, that is what you will be told.
-
Do you inspect before treating, or treat on the first visit?
It depends on the pest. For the most common ones, like ants and spiders, our technicians treat on the first visit rather than making you wait for a separate appointment. For rodents, termites, and certain specialty pests, we start with an inspection so the problem can be identified and the work scoped properly before anything is applied.
-
What is the difference between a one-time service and a regular service plan?
A one-time service addresses a current problem and works well for an occasional flare-up or ahead of a special event. It carries a 30-day warranty, and for a year afterward you can request additional visits at a discounted rate, at whatever frequency you choose, each with its own 30-day warranty. There is no contract.
A regular plan lets us reduce pest populations steadily over time, which is the better fit for long-term management, and it covers return visits between services. If you start with a one-time service and decide to move to a one-year plan during the 30-day warranty window, we credit what you have already paid toward the plan.
-
What happens if pests come back between scheduled visits?
We come back and handle it at no additional charge, and that coverage runs year-round rather than for a set window after your last treatment. It is worth asking any company how long its callback coverage lasts and what it includes, because many cover callbacks free only within 30 days of the last treatment and charge after that. For plan customers we aim to respond within a day, often the same day.
-
How often should my home be treated?
For most homes, quarterly exterior treatments are the most common interval for general pest management, covering ants, spiders, occasional invaders, and the large outdoor cockroaches many people call waterbugs. German cockroaches are not part of the regular plan and are handled as a separate specialized service.
Some properties do better on every-other-month service, particularly those bordering open space or hillsides, which is common in Canyon Country, Stevenson Ranch, and Saugus, where pressure from outdoor insects is higher. It is also the better fit when a household simply has less tolerance for seeing pests.
Specific pests run on their own schedules. Rodent programs and termite plans are evaluated case by case. Flea, bed bug, German cockroach, and other targeted treatments are scheduled based on confirmed activity rather than on a prevention cycle.
-
Do you treat the inside of the home too?
Yes. Most customers have the interior treated on the first visit if there is a lot of activity indoors. On maintenance visits the focus shifts to the exterior to keep pests from getting in, which also keeps treatment materials out of your living space. If something flares up inside, we can treat the interior on the next visit or make a special trip.
-
What does service cost?
Pricing depends on the size of the home and the lot that needs service, along with the pests being targeted. Our starting points, all subject to change:
- Recurring Three Zone pest plan, from $42 per month
- One-time service, from $195
- Full comprehensive termite and wood-destroying organism inspection, from $125 (the limited or spot inspection is free)
- Flea control, from $250
- German cockroach service, from $220
- Wasp service, from $125
Rodent work, termite treatment, NatureShield, and commercial service are quoted after we understand what the property calls for. Call the office, tell us what you are seeing, and we will price it accordingly.
-
Why are services like termites, German cockroaches, and fleas not covered under the regular plan?
Pests like termites, German cockroaches, and fleas need specific treatment protocols and often several visits to bring under control. They are priced and scheduled separately from the general plan rather than bundled into it.
-
Why is rodent control not included in the regular plan price?
Three reasons. Rodents need different control methods than general crawling insects. Not every customer wants or needs rodent service. And rodent work varies a great deal by property, including whether the activity is inside or outside, the size of the property, and the conditions that support rodent populations. If you need it, we can add rodent service once we have looked at what your property calls for.
-
Does the regular plan cover mosquitoes?
No. Our regular service covers general crawling insects. Flying insects can travel into your yard from anywhere, so they are not covered. A neighbor with a broken fountain or a pool holding stagnant water can create a breeding site, and treating your yard will not stop those mosquitoes from flying over.
-
Why does the NatureShield option cost more than standard treatment?
NatureShield is botanically based and uses fewer synthetic materials. Botanical materials break down faster, so pests can rebound sooner and the service usually calls for more frequent visits to keep pressure down. That visit frequency is what drives most of the price difference.
-
Do you service businesses?
Yes. We handle offices, industrial and warehouse buildings, property management companies, and homeowners associations. We do not service restaurants or other food-handling facilities, which require compliance documentation and after-hours crews we are not set up to provide.
-
How soon can someone come out?
We try to get a technician out the same day when you call during business hours, which are Monday through Friday, 8:00 a.m. to 5:00 p.m. An after-hours line handles genuine emergencies.
-
-
Pets, Children, and Treated Areas
-
How long after an exterior treatment should I keep my pets inside?
Until the material has dried. Drying time varies with the weather, and on hot days it can be a matter of minutes. Step outside and confirm the treated surfaces are dry before letting pets back out.
-
How long do I need to stay out of the house after an interior treatment?
Until the material has dried. Running ceiling fans or opening windows speeds that up. As a general rule, check after a couple of hours, and follow the preparation sheet that comes with your service agreement.
-
How are products applied when there are pets in the home?
Every product we use is applied according to its label. The label governs how much is used, where it goes, and how long it stays active, and our technicians follow it.
Keep pets away from treated areas during application and until the material has dried. Some pets may drool or react to an unpleasant taste if they contact a treated surface. If you know your pet is prone to licking surfaces, tell your technician so treatment can be planned around that, and tell us about anything else on the property we should work around, including edible plants.
Where it fits the situation, such as a spider living in children's play equipment, we may use a botanical material with an essential oil as the active ingredient, which controls the spider without leaving a long-lasting residue behind.
-
What if my pet eats the granules?
Some of the bait granules we use to draw insect feeding are boric acid based. Keep pets out of any treated area, and if you believe your pet has eaten treatment material, contact your veterinarian.
-
Can lizards or other small animals get into the bait stations?
Our exterior rodent bait sits in tamper-resistant stations that are weighted and locked, which is what keeps children and pets from reaching the bait. It is technically possible for a very small animal to get inside a station. The bait itself is formulated for rodents and contains a bittering agent added to make it unpalatable.
-
-
Ants and Spiders
-
Why do ants get into homes in summer and after rain?
The ant behind most calls here is the Argentine ant, which forms very large colonies that can span a whole neighborhood. Two things push them indoors:
- Heat. During long hot, dry stretches, colonies move inside looking for moisture and cooler temperatures. This is behind the heavy ant activity we see in July and August.
- Rain. Heavy rain saturates the soil where they nest and disrupts their underground galleries, which pushes colonies to relocate. Winter and spring rain, and big changes in irrigation, commonly start ants trailing along exterior walls and in through door thresholds and plumbing gaps.
-
Why do store-bought ant sprays seem to make the problem worse?
This comes up constantly with Argentine ants. Store sprays are usually repellent, meaning ants can detect them and avoid the treated area. The sprays knock down the foragers you can see, but they also break up the colony's trails and scatter the rest, which can leave you with several smaller nests instead of one.
Our approach uses materials the ants cannot detect. Workers travel through the treatment, pick it up, and carry it back to the colony, so the material moves through the population rather than stopping at the surface. Treatment around the foundation, entry points, and landscaping supports that over the longer term. Full effect usually takes about three to seven days, though most people notice an improvement within a day or two.
-
What are granules, and how do they help?
The granular materials we use work in different ways. Some are bait-like and draw pests in to feed. Others release slowly, or release with moisture, and carry treatment into places a spray cannot reach well, such as behind heavy shrubbery against an exterior wall. When rain is coming, granules hold up better than a surface spray. Your technician picks the material based on the weather and the property conditions at the time of the visit and in the days ahead.
-
Are black widow spiders common in Santa Clarita?
Yes. Western black widows are among the most frequently encountered venomous spiders here. They do well in our warm, dry climate and turn up in undisturbed, sheltered spots: wood piles, stacked lumber, garage corners, under patio furniture, inside irrigation valve boxes, and along the base of block walls. Two habits worth keeping in a Santa Clarita home are wearing gloves when you move things stored outdoors and using a flashlight before reaching into a dark space.
-
What is a brown widow spider?
The brown widow is an invasive species that has spread through Los Angeles County, including Santa Clarita, since it was first found in Southern California in the early 2000s. It is tan to brown with an orange or yellow hourglass on the underside, and its egg sacs are spiky and white, which makes them easy to spot. Bites happen and can cause local pain, though serious reactions are much less common than with the black widow. Brown widows turn up in the same places black widows do.
One myth worth clearing up: brown recluse spiders are not native to Southern California.
-
Do scorpions live in Santa Clarita?
Some do, though not in the numbers seen in the desert communities further out. The bark scorpion, the one dangerous species in the United States, is not established here. Sightings pick up in the warmer months.
Scorpions get in through gaps around pipes, door thresholds, and weep holes in stucco. They are active at night and glow under UV light, so a blacklight is a useful way to check. Shaking out shoes left in the garage is a good habit in any community this close to open desert.
-
How do you treat for spiders?
Spider work combines a few things. Our technician applies targeted treatment where spiders hide and travel: along the base of exterior walls, inside garage perimeters, under eaves, and around entry points. Web removal during service is part of it, since that takes down egg sacs. Because spiders feed on other insects, an ongoing program that reduces general insect pressure, their food source, is often the most useful long-term tool. Sealing gaps around doors, windows, pipes, and vents helps reduce how many get inside.
-
Will flea treatment also help with spiders and other crawling pests?
Some of the materials used in flea treatment help control spiders and other pests as well. If you are dealing with more than one problem, tell the office so your technician can plan the visit accordingly.
-
-
Cockroaches
-
I only saw one cockroach. Do I still need a professional?
It depends on the species. A large American cockroach, reddish-brown and an inch and a half or longer, may be a lone wanderer that came in from outside, which is common here in warm months. Worth watching, but not necessarily an infestation.
If the cockroach was small and light brown, consistent with a German cockroach, an inspection is worth arranging even for a single sighting. German cockroaches are rarely alone, and a visible one often means a population is already established and competition for food is pushing individuals into the open. They are most active at night, so seeing one during the day should be read as a warning sign rather than reassurance. If you can, collect an intact sample for identification.
-
How does professional German cockroach treatment differ from store-bought sprays?
Many consumer aerosols are repellent or contact products. They knock down the cockroaches you can see but scatter the rest deeper inside walls and cabinets, which makes the problem harder to treat.
We use gel bait placed precisely where cockroaches hide, under appliances, in cracks, and in protected spots the label allows. Cockroaches feed on the bait and pass the material to others in the population, which reduces it without the scattering that spraying causes. We apply a material alongside the bait that keeps young cockroaches from maturing, so the cycle is interrupted as well. Complete control of an interior infestation usually takes two to three weeks, followed by monitoring.
-
-
Rodents
-
I hear something in my attic at night. Is it rats?
Movement in the attic at night is a common sign of roof rat activity here, though the noise can also come from house mice or from animals we do not handle. Roof rats are active at night, and people usually describe scurrying, scratching, or a rolling sound, which is often nuts or seeds being moved around. You may also notice chewed wires, damaged insulation, gnaw marks on beams, or dark droppings around half an inch long near nesting areas. Squirrels are active during the day, which is one way to narrow it down. An inspection confirms what is up there before any treatment starts.
-
Do you handle wildlife?
No. Anything larger than a rat is considered wildlife, and that work requires a license we do not hold, so we refer it to a wildlife specialist. If an inspection turns up something other than rats or mice, we will tell you what you are dealing with and point you toward the right company.
-
How do you handle rats in the attic?
Rodent work follows three steps:
- Inspection. We identify where they are getting in, including gaps in the roofline, around fascia boards, at utility penetrations, and at attic vents, and assess how much activity is inside. You receive a written report.
- Sealing. We seal the entry points with durable materials. This is the step that resolves the problem, because no trapping program holds up if rodents can keep coming back in. Sealing typically carries a six-month warranty, though the term can depend on construction features and roof type.
- Trapping. Traps are set inside, and we return for follow-up visits, typically over about four weeks, to check them and remove anything caught. Most problems are resolved within those visits.
For exterior activity, bait may be used in tamper-resistant stations where the label allows. California has restricted certain rodent baits because of their effect on wildlife, and we use only baits approved for use in this state.
-
Why do I still see rats and mice in my yard even though I have bait stations?
Rodent numbers across the region have been growing, and state restrictions have reduced the tools available for controlling them. Property conditions matter too. Homes near greenbelts, with fruit trees, or with pet or wildlife feeding stations tend to draw rodents in, and competing food sources reduce how much bait gets eaten.
-
What if my pet catches or eats a rodent that may have consumed bait?
Worth answering directly. The exposure we manage most carefully is direct access to the bait itself, which is why our bait sits in tamper-resistant stations serviced by trained technicians rather than loose on the ground. The bait also contains a bittering agent intended to make it unpalatable to people and pets. We do not describe the risk as zero.
To reduce it: keep pets away from the stations, do not let pets play with or eat dead or dying rodents, and pick up any rodent carcasses promptly using gloves.
If you would rather not use traditional bait at all, we also offer a rodent fertility program. It uses a bait designed to reduce breeding rather than to control rodents quickly, so the population declines over time instead of dropping fast. It costs more and has to be maintained consistently, and if the service stops the effect fades and numbers can rebound where food, water, and shelter still support them.
Call the office and we will talk through which approach fits your property and your pets.
-
Are gophers covered under pest control?
No. Pocket gophers are common throughout the Santa Clarita Valley, especially on properties bordering hillsides, parks, or open space, and they damage lawns, gardens, ornamental plantings, and irrigation lines. Gopher work requires an agricultural license we do not hold, so gophers are not part of our pest control plans. Call the office and we will point you in the right direction.
-
-
Flies, Drain Pests, and Carpet Beetles
-
Why am I getting gnats or fruit flies around my drains?
Drains build up an organic film that becomes a breeding site for certain small flies. Clearing that buildup usually brings the problem under control. Enzymatic bio-cleaners break the material down, and customers on regular service can have us perform a drain treatment.
-
Why is my house suddenly full of flies?
A sudden indoor fly problem usually means an animal has died in a wall or the attic, or that trash sat in the house too long. By the time the flies appear the source is often already gone, and the practical remedy is to open doors and windows and let them out. It generally clears up on its own within a few days.
-
What are carpet beetles, and why does spraying not solve them?
Carpet beetles feed on wool, feathers, animal hair, and similar materials, so a surface spray does not address what is sustaining them. Start with sanitation. Vacuum thoroughly everywhere, especially behind furniture where the dust and hair they feed on collects, then empty the vacuum into a bin outside. That often resolves the problem on its own. If it persists, an inspection can determine why.
-
I keep chickens and I am getting mites in the coop. What can be done?
This one sits outside our service set, so we are not the right people to advise on it. Check with an expert in poultry farming, who can walk you through the options for a coop.
-
-
Bed Bugs
-
Why do you only offer tent fumigation for bed bugs?
Bed bugs hide extremely well, and people who call about them are usually worried about activity in places they cannot see. We offer tent fumigation because it is a whole-structure treatment that reaches bed bug activity in both visible and hard-to-access areas of the home.
Fumigation suits single-family homes. If it is not the right fit for your situation, there are pest control firms that offer more localized bed bug treatment.
-
-
Termites, WDO Inspections, and Real Estate
-
Are termites common in Southern California?
Yes. Termites are common throughout Southern California, including the Santa Clarita Valley, and our warm climate lets colonies stay active year-round. Two species account for most structural infestations. Western subterranean termites live in soil and enter through foundations, cracks, and utility penetrations. Western drywood termites live inside dry wood such as framing, fascia boards, and attic timbers. Because they are so widespread here, periodic inspection is common for homeowners.
-
What are the signs of termite activity in my home?
Signs vary by species.
- Subterranean termites: mud tubes running along foundation walls, piers, or studs, wood that sounds soft or hollow when tapped, and swarming activity in the spring, typically on warm, sunny days after rain.
- Drywood termites: small piles of six-sided fecal pellets beneath baseboards, window frames, or furniture, small kick-out holes in wood surfaces, and swarmer activity that in Southern California typically runs August through October. Drywood swarms are not limited to one time of day, and homeowners often notice them in the afternoon.
Do not confuse ant swarmers with termite swarmers. Ants have a pinched waist, bent antennae, and wings of unequal length. Termites have a straight body, straight antennae, and two pairs of wings the same length. Both swarm, both are alarming, and they call for different responses.
-
Do termites ever go away on their own?
Rarely. Subterranean colonies can hold tens of thousands of individuals and stay active for years where moisture and food are available. Drywood colonies are smaller but can persist inside structural wood for years while their galleries expand. Even when visible activity stops for a while, the colony is often still there in walls, framing, or the soil beneath the structure. An inspection and treatment are normally what it takes to bring an infestation under control and limit further damage.
-
Do you offer a free termite inspection?
Yes. Our limited or spot inspection is free. It covers the area of concern plus portions of the inside and outside of the home, and the inspector advises you on next steps and provides a report and a bid if one is needed. A limited inspection does not produce a clearance.
For a complete evaluation or a home sale, we perform a full comprehensive inspection covering the interior, exterior, attic, garage, and subarea where present. That inspection starts at $125, subject to change, and is priced by home size, access, and construction type.
-
What is the difference between tenting and a local termite treatment?
Whole-structure fumigation, commonly called tenting, encloses the entire structure and introduces a fumigant gas. Because the gas moves through the structure, it addresses drywood termite activity in accessible and inaccessible wood throughout the building in one treatment. Everyone has to be out of the home while it is underway, and your inspector confirms that schedule when the work is booked. Fumigation leaves no residual protection afterward.
A localized or spot treatment addresses a specific infestation we have located, without tenting. We can reach wood inside walls by drilling through the drywall into the studs. What we often cannot reach is wood above ceilings or between floors. And any infestation that has not been found and identified is not treated, because a localized treatment only affects the areas we work on.
That distinction matters more than it sounds. A single home can carry several separate drywood infestations in different areas, and they are usually separate colonies rather than one connected problem. Treating one area does nothing to the others, which is the practical argument for fumigation when activity turns up in several places. If you choose a treatment less extensive than fumigation and later decide while still under warranty that the home should be tented, we credit 40% of what you paid for the lower treatment toward the fumigation.
For subterranean termites, soil treatment with a liquid material is the standard approach. We treat directly rather than using bait or monitoring station systems, which are built around species and conditions found in other parts of the country. Fumigation does not work on subterranean termites, because the colony is in the soil rather than in the structure.
-
Is a termite inspection required to buy or sell a home in California?
Not automatically. In California a termite inspection is not a standard contract requirement for closing. It is a negotiable item, and buyers typically order one the way they would order a home inspection.
VA loans are the loan type most likely to require one. Out-of-state lenders, usually online lenders unfamiliar with California practice, occasionally request a report as well. Requirements differ in other states.
-
What is the difference between an inspection report and a clearance?
A clearance is not a separate document. It is a certification statement placed on a document, confirming there is no active evidence of infestation or infection. That statement can go on an inspection report, a reinspection report, or a Notice of Completion, which are three different documents.
So a report that lists no findings is not the same as a clearance. When an inspection finds nothing, nothing is noted on the report, and on its own that is not a certification.
You can request a clearance on a full comprehensive inspection if nothing is found, or once any work that was required has been completed. Our free limited or spot inspection does not produce one.
-
-
Bees and Wasps
-
I have a beehive on my property. Can you remove it?
In most cases we refer you to a beekeeper rather than treat the colony. Removal and relocation is specialist work and a beekeeper is the right call for an established hive. We handle bee situations directly only where there is an immediate, life-threatening emergency.
Do not try to remove or disturb an established colony yourself. Africanized honeybees are established throughout Southern California, which makes this genuinely hazardous. Do not spray a hive with water, knock it down, block the entrance, or use a consumer aerosol on an active colony.
One thing worth knowing if a colony is inside a wall: removing the bees is not the end of it. The comb and honey have to come out as well, or you get fermentation, wax moth activity, honey leaking and staining, damage to drywall and interior finishes, and new swarms drawn to the leftover wax. That usually means opening a section of the wall and coordinating between a contractor and either a beekeeper or a pest control professional.
-
What wasps are common in this area?
Three come up most often:
- Western yellowjackets nest in the ground or in walls and are very common here. Colonies can reach tens of thousands by late summer and fall, when food gets scarce and they push into outdoor dining areas and trash cans. Yellowjackets are a specialized treatment. We inspect first and provide an estimate rather than handling them on a regular service visit.
- Paper wasps build open, umbrella-shaped paper nests under eaves, in attic vents, and on outdoor structures. Much less aggressive than yellowjackets, though they will sting if the nest is threatened.
- Mud daubers are solitary wasps that build cylindrical mud tubes on exterior walls and under eaves. They are very unlikely to sting and are generally a nuisance rather than a problem.
Unlike bees, wasps can sting more than once. Paper wasp and mud dauber nests are covered under our Three Zone plan, and we also handle them as a standalone service. Yellowjackets are quoted after an inspection.
-
-
Weather and Service Visits
-
Rain is forecast. Why am I still scheduled for service?
We do not apply outdoor materials during active heavy rain. On days with light drizzle or passing showers, service generally goes ahead with the approach adjusted for conditions.
When rain is in the forecast we switch to slow-release granules applied to the soil areas around the property, so that pests trying to move indoors during wet, cold weather run into treated ground on the way. Your technician selects materials based on the weather and property conditions at the time of the visit and in the days ahead.
If you have a concern about an upcoming visit, call the office and we will work out the timing with you.
-
When should I turn off my sprinklers, and for how long?
We generally ask that sprinklers go on a two to three day rain delay after treatment for the best result.
-
Why are pests worse after it rains?
Most of our rain falls between November and April, and it shifts pest activity in several ways:
- Ant colonies in saturated soil move to higher, drier ground, which often means your house.
- Moisture and flooded hiding places push cockroaches and silverfish out of drains, sewers, and outdoor harborage.
- Roof rats look for shelter in attics and structures when outdoor cover floods.
- Subterranean termite swarmers are triggered by moisture and warmth after the first significant rains of the season.
A regular program accounts for these seasonal shifts, and your technician may recommend adjusting the treatment frequency or the materials used after a significant weather event.
