Expert Pest Control Services in Los Angeles, California

Irrigation keeps Argentine ant colonies strong through dry months, and UC research in Los Angeles found foraging peaks in the hottest weather. These ants form huge colonies with many queens, so one nest can send trails into several homes at once. They hunt moisture first, which is why kitchens and bathrooms see them before anywhere else. Store sprays knock down the workers you see and leave the colony untouched, so the trail returns within days. We use slow-acting baits the workers carry back to the nest, combined with sealing the gaps around pipes and doors where they enter.

German cockroaches thrive in dense housing, and downtown and Koreatown buildings give them everything they need. They hide in warm, tight spaces behind stoves, under sinks, and inside appliance motors, breeding fast when food and water are close. Spotting a few at night usually means many more are hiding. Over-the-counter foggers push them deeper into walls and spread them to neighboring units. We treat with targeted baits and crack-and-crevice work at the harborages, then coach you on the sanitation steps that keep them from coming back.

American cockroaches live in sewers and storm drains across the city and climb into homes through floor drains, sewer lines, and dry traps. They are most active at night, and warm weather brings them out in force. A basement, garage, or first-floor bathroom with a floor drain is their usual doorway. We treat the entry points, service drain lines, and place targeted treatments where they travel, then show you how to keep traps wet and drains sealed so they stay out.

Drywood termites live entirely inside the wood they eat, and Los Angeles has plenty of older homes with original framing, trim, and eaves. They need no soil contact, so attics and window frames are fair game. Swarmers appear in spring and leave behind piles of tiny six-sided pellets on sills and floors. Damage grows silently for years before paint starts to bubble or wood sounds hollow. We inspect with a full walk-through, confirm the species, and treat with localized treatments or whole-structure methods depending on how far the colony has spread.

Subterranean termites live in the soil and reach wood through mud shelter tubes they build up foundations and crawl-space walls. Winter rains in Los Angeles wake colonies, and poor drainage keeps them active. Swarmers are dark-bodied with equal-length wings, and tubes on a foundation wall are a clear warning sign. We break the soil-to-wood connection with liquid barrier treatments around the foundation and baiting systems that target the colony itself. Then we fix the moisture and wood-to-ground contact that invited them in.

Roof rats are smaller, darker climbers that run along power lines, tree branches, and fence tops to reach attics and rooflines. Los Angeles County health officials note rat populations are broadly distributed across the county, and dense neighborhoods with fruit trees keep them fed. They chew wiring, contaminate insulation, and leave droppings in attics. Trapping alone cannot solve it, because new rats follow the same routes in. We combine trapping with exclusion, sealing every gap along the roofline, vents, and eaves, then verify the attic stays quiet.

Black widows build messy webs in quiet, undisturbed corners of sheds, garages, woodpiles, and under patio furniture. Warm LA weather lets them stay active most of the year. They avoid people, but a hand reaching into a dark corner can meet one. We remove webs and spiders directly, treat the harborages, and clear the clutter and debris that give them shelter. Simple habit changes, like moving firewood away from the house, do a lot of the prevention work.
