California licensed, SPCB Lic. #9119. Where your house sits, from Bair Island to the Edgewood Park side, changes the plan.
Home maintenance
What home maintenance keeps pests out of a Redwood City house?
Plan around Redwood City’s short wet winter and long hot summer. Rain falls almost entirely from November to April, and July highs average 81°F. Winter brings rodents and ant invasions; summer brings drywood termites, yellowjackets and water-seeking ants. Mosquitoes matter more near the lagoons and sloughs.

Fall: gutters, grading and sealing
Clean gutters, extend downspouts and seal gaps at pipes, vents and the garage door in September and October, before the first rain and the rodent season.
Winter: check the attic and garage
December is the wettest month. Look for droppings on attic insulation and garage shelves, and listen for scratching at night.
Spring: dump standing water
In Redwood Shores and near Bair Island, empty saucers, buckets and clogged gutters weekly from spring on. The county district handles mosquitoes and wants to hear about day-biting ones.
Early summer: look for wasp nests
Yellowjacket queens start nests from April to June. Find ground holes and eave nests while they are small, and report ground nests to the county district.
Summer: watch the hot side of the house
Check attic vents and sunny-side trim for drywood pellets, keep sprinklers off the walls, and fix leaks that draw ants indoors.
When to do it
A short round each season, with the most work in September and October.

Common Questions
Residential Pest Control FAQs for Redwood City
What should a new Redwood City homeowner check first for pests?
Start with the framing and the roofline. Pull the WDO report from the sale and read the Section 2 list, since conditions like earth-to-wood contact, a damp sub-area or missing vent screens are what turn into Section 1 findings later. Then walk the roof edge for gaps at the fascia and vents, which is how roof rats get into attics here. Both are far easier to handle before they become active infestations.
Do Redwood Shores homes need different pest service than the older neighborhoods?
Yes, in emphasis. Redwood Shores sits on low bayfill beside Bair Island, so the priorities there are moisture in accessible framing, subterranean termite activity and seasonal ant movement, and much of the exterior falls under an association rather than the individual owner. The older neighborhoods west of El Camino Real skew toward drywood termites in roof framing and roof rats in attics. The inspection sets the plan either way.
Can one company handle both the termites and the crawl space work in a Redwood City house?
Yes — termite treatment, sub-area moisture work and rodent exclusion are the same job seen from different angles, and splitting them across companies is how conditions get missed. A vapor barrier that lowers sub-area humidity removes a Section 2 condition. Exclusion that seals the roofline stops the contamination that ruins attic insulation. We do the inspection, the treatment and the structural pieces under one license.
