Frequently Asked Questions

Spider Questions

Are black widow spiders common in Santa Clarita? 

Yes, black widows (Latrodectus hesperus, the Western black widow) are one of the most frequently encountered venomous spiders in SCV and throughout Southern California. They thrive in our warm, dry climate and are typically found in undisturbed, dark, sheltered areas: wood piles, stacked lumber, garage corners, under patio furniture, inside irrigation valve boxes, and along the exterior base of block walls. 

Pro tip: Regularly wearing gloves when moving items stored outdoors and using a flashlight before reaching into dark spaces are practical everyday precautions in SCV homes. 

What is the brown widow spider, and is it dangerous? 

The brown widow (Latrodectus geometricus) is an invasive species that has become widespread throughout Los Angeles County, including Santa Clarita, since it was first detected in Southern California in the early 2000s. It is tan to brown with a distinctive orange or yellow hourglass on the underside of its abdomen. Its egg sacs are spiky and white, making them easy to identify. 

Laboratory studies suggest brown widow venom may be similar or slightly more potent per unit than black widow venom; however, the brown widow is thought to inject far less venom per bite and is generally less aggressive. Bites do occur and can cause local pain and discomfort; systemic reactions are far less common than with the black widow. Brown widows often outcompete or replace black widows in some urban microhabitats, so it is common to find them in the same locations: under patio furniture, inside folded outdoor equipment, and around exterior eaves. 

*Despite common myths, brown recluse spiders are not native to Southern California.

Do scorpions live in Santa Clarita? 

Scorpions are present in Santa Clarita Valley, though they are not as consistently abundant as they are in the eastern Mojave Desert communities of the Antelope Valley or the Inland Empire. The species most likely to be encountered here is the Paruroctonus (burrowing scorpion) group and, less commonly, the California common scorpion (Paruroctonus silvestrii). The Arizona bark scorpion (Centruroides sculpturatus), which is the only life-threatening scorpion species in the U.S., is not established in the Santa Clarita area. Sightings typically increase in warmer months (spring through fall). 

Scorpions enter homes through gaps around pipes, door thresholds, and weep holes in stucco. They are nocturnal and fluorescent under UV (blacklight), which is a useful inspection tool. 

Pro tip: Shaking out shoes left in the garage before putting them on is a good habit in any SoCal desert-adjacent community. 

How do exterminators treat for spiders? 

Spider treatment involves several complementary strategies. A licensed pest control professional will apply targeted residual insecticide treatments to the areas where spiders harbor and travel (along the base of exterior walls, inside garage perimeters, under eaves, and around entry points). We also focus on web removal during service, which eliminates egg sacs and disrupts recolonization. Because spiders feed on other insects, an effective ongoing pest management program that reduces general insect pressure (their prey) is often the most important long-term tool for spider control. Exclusion—sealing gaps around doors, windows, pipes, and vents—is also recommended to reduce entry. 

Rodent Questions

I hear something in my attic at night. Is it rats? 

Nighttime movement sounds in the attic are a common sign of roof rat activity in Santa Clarita. However, attic noises can also come from house mice, squirrels, raccoons, opossums, and rarely bats.  

Roof rats are nocturnal, and residents often describe the sound as scurrying, scratching, or rolling — the rolling sound may be nuts, seeds, or other debris being moved. You may also notice chewed wires, insulation damage, gnaw marks on wood beams, or dark, spindle-shaped droppings (roughly 1/2 inch long) near nesting areas. It is worth noting that other wildlife — including squirrels (daytime), opossums, or raccoons — can also produce attic sounds, and their management differs from that of rats. A proper inspection by a licensed technician will help confirm which animal is present before treatment begins. 

How do you get rid of rats in the attic? 

Rat removal typically follows an integrated approach: 

• Inspection: Identifying all entry points, including gaps in the roofline, around fascia boards, at utility penetrations, and at attic vents, along with assessing the level of activity inside.
• Exclusion: Sealing all entry points with durable materials (hardware cloth, copper mesh, or sheet metal flashing). This is the most important long-term step, as no trapping program is effective without denying re-entry. 
• Trapping or baiting: Snap traps are the most common method inside attic spaces. Rodenticide bait stations may be used in exterior areas in tamper-resistant stations where label directions allow. California regulations govern the use of second-generation anticoagulant rodenticides, and licensed professionals are required to follow state Department of Pesticide Regulation rules regarding placement and monitoring. 
• Cleanup: Attic sanitation—removal of contaminated insulation, feces, and nesting material—and insulation replacement may be recommended depending on the extent of infestation. 

Are gophers covered by pest control, and are they a problem in SCV? 

Botta’s pocket gophers (Thomomys spp.) are common throughout Santa Clarita Valley, particularly in residential properties that border hillsides, parks, or undeveloped open space, as well as in neighborhoods with established landscaping and irrigation. They are a significant pest for lawns, gardens, and ornamental plantings, and can also damage irrigation lines. Gopher management typically involves trapping (the most reliable method) or below-ground rodenticide bait placed directly into active tunnel systems using a probe. Surface bait is generally not effective for gophers. Gopher control requires an ‘Agricultural License’ thus they are not included in our Structural Pest Control plans. We can refer you to a company holding such a license. 

Cockroach Questions

I only saw one cockroach. Do I still need an exterminator? 

It depends on the species. If the cockroach you found was a large American cockroach (reddish-brown, 1.5 inches or longer), it may be an isolated wanderer that entered from outside, which is common in Southern California during warm months. However, this is still worth noting and monitoring. 

If the cockroach was small and light brown—consistent with a German cockroach—a professional inspection is strongly advisable, even for a single sighting. German cockroaches are rarely found alone and are often seen when a population is already established, and food competition is forcing individuals out into the open. Daytime sightings or activity in open areas can indicate that a population is already established.

Pro tip: German cockroaches are most active at night. If you see one during the day or in an exposed location, treat that as a warning sign rather than reassurance that the problem is small. If possible get a sample for identification (un-smashed). 

How do professionals treat German cockroaches differently from over-the-counter sprays? 

This is one of the most important distinctions in pest control. Many consumer aerosol sprays act as repellents or contact killers. They may kill visible cockroaches but can scatter the population deeper into harborages and wall voids. This can make an infestation harder to treat effectively. Licensed professionals use gel bait formulations (e.g., fipronil or indoxacarb-based products) placed precisely inside harboring areas, e.g., under appliances, in cracks, voids, and protected areas near harborages where labels permit. Cockroaches consume the bait and pass the active ingredient to nestmates through secondary contact and feeding. This can eliminate a population without the pest dispersal caused by spraying. Insect growth regulators (IGRs) are also commonly applied to disrupt the reproductive cycle. In heavily infested commercial settings, flush-and-treat inspections to drive cockroaches out of harborage may also be used to assess the full extent of activity before and after treatment. 

Ant Questions 

Why do ants invade homes in summer and after rain? 

The dominant ant species in most urban areas of Southern California is the Argentine ant (Linepithema humile). Argentine ants form massive "super colonies" that can span entire neighborhoods; unlike many native ant species, Argentine ant colonies cooperate with one another rather than competing, which allows populations to grow to enormous sizes. 

Two triggers drive indoor invasions locally: 

1. Heat: During prolonged hot, dry spells—which many Southern California residents know well—Argentine ant colonies move indoors in search of moisture and cool temperatures. This explains the heavy ant activity often reported in July and August. 
2. Rain: Heavy rainfall can saturate soil nesting areas and disrupt underground galleries, causing colonies to relocate temporarily. SCV's periodic winter and spring rain events (and any significant irrigation changes) commonly trigger trailing activity across exterior walls and into homes through door thresholds and plumbing penetrations. 

Why do store-bought ant sprays seem to make the ant problem worse? 

This phenomenon is commonly observed with Argentine ants. Repellent sprays kill visible foragers but disrupt the colony’s foraging trails and can scatter workers, sometimes leading to the formation of multiple satellite nests (“budding”).

Professional treatment for Argentine ants relies primarily on non-repellent liquid or granular bait products that worker ants carry back to the colony and share with nestmates. This allows the active ingredient to move through the population rather than just eliminating foragers at the surface. Exterior treatments using non-repellent residual products around the structure's foundation, entry points, and landscaping also help with long-term management. 

Termite Questions

Are termites common in Southern California? 

Yes. Termites are extremely common throughout Southern California, including the Santa Clarita Valley. The region’s warm climate allows termite colonies to remain active year-round. Two species are responsible for most structural infestations:

• Western subterranean termites (Reticulitermes hesperus) – live in soil and enter structures through foundations, cracks, and utility penetrations.
• Western drywood termites (Incisitermes minor) – live directly inside dry wood such as framing, fascia boards, and attic timbers.

Because termites are so widespread in the region, most homes will experience some level of termite activity over time. This is why termite inspections are routinely required during real estate transactions in California and why ongoing monitoring or periodic treatment is common for homeowners.

What are signs of termite activity in my home? 

Signs vary by species. 

• For Western subterranean termites: mud tubes running along foundation walls, piers, or studs; soft or hollow-sounding wood when tapped; and swarming activity (winged reproductives, or "alates") typically from late winter through spring. 
• For Western drywood termites: small piles of six-sided fecal pellets beneath baseboards, window frames, or furniture; small holes in wood surfaces (kick-out holes); and swarmer activity, which in Southern California typically peaks in late summer/fall (July – September). 

Pro tip: Do not confuse ant swarmers with termite swarmers. Ants have a  pinched "waist," bent antennae, and unequal wings; termites have a straight body, straight antennae, wings that are equal length. Both swarm and both can be alarming, but they require completely different responses. 

Do termites ever go away on their own?

Termite infestations rarely resolve without intervention. Subterranean termite colonies can contain tens of thousands to hundreds of thousands of individuals and may remain active for many years if moisture and food sources are available. Drywood termite colonies are smaller but can persist inside structural wood for years while gradually expanding their galleries.

Even if visible activity temporarily stops, the colony is often still present within walls, framing, or soil beneath the structure. Professional inspection and treatment are typically required to eliminate the infestation and prevent continued damage.

What's the difference between tenting (fumigation) and local termite treatment? 

Whole-structure fumigation (tenting) involves enclosing the entire structure with a tent and introducing a penetrating gas fumigant (sulfuryl fluoride). It is highly effective at eliminating drywood termite infestations throughout all accessible and inaccessible wood in the structure in a single fumigation treatment. It requires occupants to vacate the home for the better part of three days and two nights and does not provide a residual preventive effect after aeration is complete. 

Localized or "spot" treatments address specific, accessible infestations without full structure tenting. The ideal treatment ‘spot treatments’ are appropriate for localized, accessible drywood infestations, but are riskier for wood that is inaccessible within wall cavities or above ceilings. 

For subterranean termites, soil treatment with liquid termiticide (creating a chemical barrier in the soil) is the standard approach. Fumigation is not effective against subterranean termites because their primary colony is in the soil, not the structure. 

Wasp & Bee Questions 

Can I remove a beehive myself? 

Attempting to remove or disturb an established bee colony or hive without professional equipment is dangerous, particularly because Africanized honeybees are established throughout Southern California. Do not spray a hive with water, attempt to knock it down, block the entry, or apply consumer aerosol products to an active colony. 

A licensed structural pest control professional can treat the colony effectively. If a colony is inside a wall void or structural cavity, treatment alone is not sufficient; the comb and honey must also be removed to prevent secondary pest problems (including fermentation, wax moth infestation, honey leakage, staining, and potential damage to drywall or interior finishes) and to discourage recolonization by new swarms attracted to the residual wax and propolis. This typically requires removal of a section of the structure, which may involve coordination between a pest control professional and a contractor. 

What are common wasps? 

The most encountered wasp species in our area are: 

• Western yellowjacket (Vespula pensylvanica): A ground-nesting or wall-nesting wasp that is very common in the SCV area. Colonies can reach tens of thousands of individuals by late summer and fall, when foraging aggression peaks and food scarcity drives them to seek sugary food and protein sources around outdoor dining areas and trash receptacles. 
• Paper wasps (Polistes spp.): Build open, umbrella-shaped paper nests under eaves, in attic vents, and on outdoor structures. Far less aggressive than yellowjackets when not directly disturbed but will sting if the nest is threatened. Multiple species are present in SoCal.
• Mud daubers (Sceliphron spp.): Solitary wasps that build cylindrical mud tubes on exterior walls and under eaves. They are not social and are extremely unlikely to sting; they are generally considered a nuisance pest rather than a safety concern. Unlike bees, wasps can sting multiple times without dying. 

General Pest Control Questions

How often should I have my home treated for pests? 

For most homeowners, quarterly exterior perimeter treatments are the most common service interval for general pest management (ants, spiders, occasional invaders, and cockroach (waterbug) prevention). Some properties benefit from bi-monthly service, particularly those adjacent to open natural space, arroyos, or hillsides—which are very common in communities like Canyon Country, Stevenson Ranch, and Saugus—where pressure from wildlife and urban-edge insects is higher. 

Specific pests require their own treatment schedules: rodent programs and termite protection plans are typically evaluated on a case-by-case basis and may include annual renewals or ongoing monitoring contracts. 

Flea, bed bug, and other targeted treatments are scheduled based on confirmed activity rather than prevention cycles. 

Why are pests worse after it rains in Southern California? 

Santa Clarita receives roughly 14-17 inches of rainfall annually, with most precipitation between occurring between November and April.

Rain affects pest activity in several ways: 

• Ant colonies in saturated soil move to higher, drier ground, which often means the structure. 
• Increased moisture and flooding of harborage areas can drive cockroaches and silverfish out of drains, sewer systems, and outdoor hiding places.
• Roof rats may seek shelter in attics or structures when outdoor harborage is flooded or disrupted. 
• Mosquito populations surge in the 7–10 days following standing water events in catch basins, planters, and low areas. 
• Subterranean termite swarmers are triggered by moisture and warmth following the first significant rains of the season.

A professional pest management program accounts for seasonal pressure shifts, and a technician may recommend adjustments to treatment frequency or product selection in response to significant weather events.
