Sonoma County's wet winters and long dry summers create a seasonal pest cycle that hits homes hard twice a year. When the first rains arrive, roof rats and mice push out of creek corridors, vineyards, and open space into attics and garages. When summer heat peaks, Argentine ants trail indoors looking for water. The county's older housing stock, especially around Santa Rosa's Railroad Square, the West End, and Petaluma's historic downtown, contains aging wood framing that gives both drywood and subterranean termites the conditions they need. Properties here range from dense in-town lots to rural acreage with outbuildings, and pest pressure shifts with every property type.

Pest Control Service
Sonoma County pest pressure is not constant. Rodents move toward structures when fall rains arrive and outdoor food sources dry up. Termite swarms peak in spring. Argentine ants trail indoors in summer heat. A single blanket treatment applied once a year does not address this cycle. We inspect each property and build a plan around what is actually happening at that home, at that time.
The older neighborhoods in Santa Rosa and Petaluma present a specific challenge: homes built before the mid-1900s often have original wood framing, unsealed crawl space vents, and utility penetrations that were never designed to keep rodents out. We identify every entry point during the inspection and close them with materials suited to that opening, whether it is a foundation gap, a roofline void, or a plumbing penetration.
H&I was started because the owner believed pest control should solve the problem, not generate repeat service calls. In Sonoma County, that means recommending vapor barrier installation when crawl space moisture is feeding a termite or rodent problem, not just treating the symptom. You pay only after the work is complete, and the estimate you receive before work begins is the price you pay.
At a glance
Rodent trapping and rodent exclusion are the highest-demand services in Sonoma County, where roof rats move from creek corridors and vineyard rows into residential attics and crawl spaces each fall. Termite treatments and wood-eating insect extermination address the drywood and subterranean termite activity concentrated in the county's older downtown neighborhoods. Ant sprays and insect home barrier application manage the Argentine ant trails that push indoors during the dry summer months. Insulation cleanout handles the contaminated attic and crawl space material that rodents leave behind after nesting.

Common questions from Sonoma County, CA customers about our services, process, and coverage.
Fall is the most important window for rodent exclusion in Sonoma County. As outdoor food sources in vineyards, creek corridors, and open space diminish and the first rains arrive, roof rats and mice actively seek entry into structures. Closing entry points before that migration begins keeps rodents out of attics and crawl spaces before they have a chance to nest.
Yes. Homes in older Santa Rosa neighborhoods like Railroad Square and the West End contain aging Douglas fir and redwood framing that drywood and subterranean termites target. Newer construction typically uses pressure-treated lumber and has fewer wood-to-soil contact points, which reduces but does not eliminate risk. A wood-eating insect identification inspection determines which species is present and where activity is concentrated before any treatment is applied.
Argentine ants trail indoors during Sonoma County's dry summers because they are searching for water and food. Treating only the ants you see inside does not address the colony or the entry points they are using. An insect home barrier application around the perimeter of the structure, combined with sealing the gaps they are entering through, breaks the cycle rather than just interrupting it temporarily.
Petaluma's pre-1940 homes, including the Victorian-era properties in the historic district, often have wood foundations, unsealed crawl spaces, and attic vents that invite both rodents and termites. Subterranean termites are active in the moist soil near the Petaluma River corridor, and drywood termites target the aged structural wood in attics and eaves. Rodent exclusion, termite treatments, and insulation cleanout are the most common services needed in these properties.
