Los Angeles Pest Control sends a technician to Pasadena, ZIPs 91101, 91105 and 91106, for drywood termites in older Craftsman framing, Argentine ants, roof rats and gophers. Calls are answered 24/7, a same-day visit is booked when a technician is free, and the price is confirmed on site before work starts.
Pasadena is an incorporated city about 10 miles (16 km) northeast of downtown Los Angeles and the primary cultural centre of the San Gabriel Valley. The 2020 census counted 138,699 residents. It is one of the older cities in the region, and the age of its housing is the thread that runs through most of the pest questions people call about.
Bungalow Heaven takes its name from more than 800 small Craftsman homes built between 1900 and 1930, most of them still standing. Pasadena was one of three prominent centres of American Craftsman design, and those wood-framed houses, with deep eaves, exposed rafters, original attics and trim, are the structures a termite technician spends the most time on.
Los Angeles’s long dry season, the Santa Ana winds from October and the short wet winter decide when ants, gophers and termites move.
UC IPM says drywood termites infest attics, roof framing, fascia, rafters and exposed trim, which are the very features that give a Craftsman bungalow its character. Deep eaves and exposed rafter tails are above-ground wood that stays dry, and that is the habitat drywood termites want.
These insects are rarely seen until they swarm in the daytime, typically late summer or early fall in coastal and southern regions. Hexagonal pellets beneath a small kickout hole are the diagnostic sign. A termite inspection on an older house covers the attic, eaves and trim, and drywood termite control explains local treatment versus fumigation. California's Structural Pest Control Board licenses fumigation as its own branch, Branch 1.
In California, a Wood Destroying Pests and Organisms Inspection Report is a standard document in home sales and is governed by the Structural Pest Control Act. Copies of reports filed with the Board over the preceding two years can be obtained, which can help a buyer see a property's history.
The registered company must report the address of each property inspected for wood-destroying pests, or on which work is completed, within 10 business days of the inspection starting or the work being done. Ask the technician how that filing will be handled for your property. The guide to drywood and subterranean termites explains how the report relates to treatment.
Irrigation matters in both cases. Argentine ant supercolonies spread with irrigation within weeks and fall back when it stops, and they look for water indoors in hot, dry weather. In May, when the dry season starts, watering raises their numbers quickly, so a trail on the kitchen counter in early summer is common.
Pocket gophers like the same soil. UC IPM says irrigated lawns, beds and gardens give good digging conditions all year, so crescent-shaped mounds can appear in any month. See Argentine ant control and gopher control for how bait and trapping work.
The San Gabriel Valley Mosquito and Vector Control District covers Pasadena, and it handles mosquito and West Nile surveillance, dead-bird collection and standing-water inspection. It does not handle rodents or bees, so those are for a pest technician.
The foothill side of the city shares the San Rafael Hills ground with wildlife such as coyotes, which is a matter for the California Department of Fish and Wildlife. A technician can seal entry points on a house, and our wildlife-proofing page explains that this site does not trap or relocate animals. For rats in attics, see rat and mouse control.
The Santa Ana season, from October to March, brings dry air from the northeast, and fall can be the driest, windiest stretch of the year. Then the first autumn rains arrive, and western subterranean termites swarm on calm, sunny days right after them, which is one reason fall calls about winged insects spike in the San Gabriel Valley. Spring swarms are possible too, especially in southern California.
Ants shift as well. Argentine ant colonies merge in fall and stay large through winter, and rain can drive them indoors. For a house with decades of weathered trim, a fall visit before the storms is a good time to check for gaps and wood-to-soil contact. The Los Angeles pest calendar covers the full year.
Older houses collect gaps over the years, around vents, eaves, plumbing penetrations and the foundation. Roof rats use fences, wires and branches to reach those spots and nest in attics and wall voids, and UC IPM's advice is to keep branches about three feet from the roofline and thin oleanders.
The sealing that follows control matters, and it should respect the home's character. A technician can describe what needs closing and where, and homeowners in older neighborhoods often want work that preserves original trim and vents. See attic and crawl space rodent exclusion for what sealing involves.
Pasadena's older Craftsman houses and the state's inspection-report process make a thorough wood check a common first step.
Exposed rafters, fascia and attic framing in Bungalow Heaven-era houses are the wood drywood termites infest.
A widespread infestation may need whole-structure fumigation, licensed by California as Branch 1.
Irrigated yards raise ant numbers within weeks, and the dry months push them to look for water indoors.
Watered lawns and garden beds keep soil workable, so mounds can appear in any month.

Pasadena ZIP codes we cover: 91101, 91105, 91106. Type yours to confirm, or just call.
Yes. Drywood termites live inside dry wood and are rarely seen until swarmers fly. Look for small hexagonal pellets and kickout holes, and have the attic, eaves and rafters checked.
No. UC IPM says limited infestations can sometimes be handled by replacing the wood, and extensive ones by chemical treatment, which includes fumigation. A technician inspects first and the price is confirmed on site.
Pasadena is covered under ZIPs 91101, 91105 and 91106. Use the ZIP checker if you are on the edge of those areas.
No. The San Gabriel Valley Mosquito and Vector Control District does not handle rodents or bees. A pest technician handles rats and wasp nests on private property.
