Ants, gophers and rats
Why do I see Argentine ants indoors when it has not rained?
In hot, dry weather Argentine ants look for water, and a faucet, drain or pet bowl is the nearest supply. UC IPM says bait stations are the most effective control, especially from winter to early spring. See Argentine ant control.
Why do ants come in when it rains?
Wet weather can push colonies out of saturated ground and into buildings. Trimming plants that touch the walls and sealing entrances cuts the routes. The Argentine ant guide explains how irrigation and rain change colony size.
How do I know a mound is from a pocket gopher?
Gopher mounds are crescent- or horseshoe-shaped piles of loose soil. In irrigated lawns, beds and gardens, UC IPM notes they can appear at any time of year. Trapping, after probing to find the main burrow, is the common method. See gopher control.
What attracts roof rats to my house?
Roof rats climb, nest above ground in shrubs, trees, ivy, attics and wall voids, and eat citrus and avocados on the tree. UC IPM advice is to keep branches 3 feet from the roofline and trim palm frond skirts. See roof rat control.
Does trapping rats fix the problem?
Only partly. Trapping reduces the animals inside, but gaps at vents, rooflines and pipe penetrations let new ones in. Pair rat and mouse control with attic and crawl space exclusion.
Termites and inspections
How do I tell drywood termites from subterranean ones?
Drywood termites live inside dry above-ground wood and leave small hexagonal pellets from kickout holes. Subterranean termites need soil contact. UC IPM calls subterranean termites California's most important termite pest and drywood the second. See the comparison guide.
When do termites swarm in Los Angeles?
Drywood swarmers typically fly in the daytime in summer and fall, tending to late summer or early fall in coastal and southern areas. Western subterranean termites swarm on calm, sunny days right after the first autumn rains, and may swarm in spring. Timing varies.
Do I need fumigation if I find pellets?
Not always. UC IPM says limited infestations can be handled by replacing wood, while extensive ones may need chemical treatment. Fumigation, or tenting, is Branch 1 work. An inspection decides, and the fumigation page explains the process.
What is a termite inspection report in a home sale?
California home sales commonly use a Wood Destroying Pests and Organisms Inspection Report, governed by the Structural Pest Control Act. Copies of reports filed with the Board over the preceding two years can be obtained. See termite inspection.
How soon must a company file an inspection or completion report?
Business and Professions Code section 8516(b) requires a registered company to report each property inspected for wood-destroying pests, or on which work is completed, within 10 business days of the inspection starting or the work finishing. Failing to file is grounds for discipline.
Wildlife, mosquitoes and who to call
Can a pest company remove a coyote or raccoon?
Not here. Los Angeles Pest Control does not trap, remove or relocate wildlife, and relocating nuisance raccoons and skunks is illegal in California. The California Department of Fish and Wildlife governs them. See the who-to-call guide.
Who can I call about coyotes in my neighborhood?
Start with Los Angeles County Animal Care and the California Department of Fish and Wildlife, whose Living with Wildlife advice is to remove food, water and shelter, use tight-fitting lids and lock pet doors at night. The permit line is (916) 358-2917.
Which vector control district covers me?
It depends on the address. The Greater Los Angeles County Vector Control District, the San Gabriel Valley district and the Los Angeles County West district divide the area. District treatment is for mosquitoes and similar pests, not rodents. See which district covers you.
Who handles rats if the vector district does not?
Rodent questions inside the Greater Los Angeles district go to the Los Angeles County Vector Management Program at (626) 430-5450, and a technician handles control on private property. See rat and mouse control.
Prices and plans
How much does pest control cost in Los Angeles?
It depends on the pest and the property. Cost publications list ranges, for example HomeAdvisor lists general bug and insect treatment in Los Angeles at $125 to $363, average $241. The pricing page names each publisher, and the real price is confirmed on site.
Why is the price confirmed on site, not on the phone?
Because the pest, the size of the home, access to attics and raised foundations and the severity of the infestation all change the work. A technician sees these first, then gives the price before any work starts.
Do published prices include fumigation?
Fumigation has its own published figures. Fixr lists California tent fumigation at $1.30 to $4.35 per square foot, and about $2,000 to $4,500 for a 1,500 to 2,000 square foot home. These are estimates, not quotes.
Is a recurring plan better than a one-time visit?
It depends on the pest. A one-time visit fits a single problem. Ants in an irrigated yard return as long as irrigation continues, so a recurring plan can make sense. A technician explains both.
Booking and coverage
How do I book a visit?
Call (855) 974-4733, any hour, or use the contact page form for something that can wait. Give your ZIP code and describe what you saw. A visit is booked for the same day when a technician is free.
What counts as an emergency?
Call right away for a wasp or hornet nest by a doorway, rodents loose in living space, a bed bug outbreak or roaches in a food business. Anything that can wait a day, such as an inspection report, works through the form.
Do you cover my ZIP code?
The call line covers 26 places within 25 km of downtown. The ZIP checker shows whether yours is on the list, and a call settles borderline cases.
Can I ask for the license number?
Yes. You can ask for the license number of the company that will visit before work starts. The about page explains why numbers are not printed on this site and how to verify one.
Question not answered here?
Call and ask. A technician will give you a straight answer, even if the answer is that you do not need us.
