Residential Pest Control
Residential Pest Control in San Mateo, CA
101 Exterminators provides residential pest control in San Mateo for single-family houses, townhomes and condos, California licensed under SPCB Lic. #9119. A 1920s Craftsman in Hayward Park, a slab ranch in Beresford Manor and a post-and-beam house in the Highlands do not share the same pests or the same weak points. We inspect the house you actually own.
Home maintenance
What home maintenance keeps pests out of a San Mateo house all year?
Work with San Mateo’s two seasons: a wet November to April and a dry, partly foggy summer. Most pest problems here start with water in the wrong place in winter, or with food and shelter left out in summer. A short seasonal checklist covers rodents, ants, termites and wasps for most homes.
September: gutters, downspouts and grading
Clear gutters, extend downspouts and make sure soil slopes away from the foundation before the first fall rain, which the county district ties to termite swarms.
October: seal and trim
Close gaps at pipes, vents and the garage door, and cut limbs back from the roof. Rats and mice look for shelter once the rains start in November.
Winter: listen at night
Scratching in the attic or walls during the wettest months usually means rodents. Check attic insulation and garage shelves for droppings in December and January.
Spring: watch the kitchen and the yard edge
Argentine ant trails show up after storms, and on west-side lots near Laurelwood and Sugarloaf, ticks appear on dogs after walks. Seal trail entry points and check pets after hikes.
Summer: wasps, water and wood
Look for yellowjacket holes in the lawn before August, keep sprinklers off the walls, and check exposed beams and trim for drywood termite pellets.
When to do it
A quick round at the start of each season, with the biggest effort in September and October before the rains.

Common Questions
Residential Pest Control FAQs for San Mateo
What pests should a San Mateo homeowner expect in a normal year?
Argentine ants twice a year, spiders continuously, and rodents most often through fall and winter. The ant waves track the rain — indoors when the first storms saturate the ground from November, then indoors again in late summer once the soil dries out. Roof rats push into attics as nights cool. Termites are the slow one: drywood in the older hillside neighborhoods, subterranean on the bayshore side, and usually found by inspection rather than by symptom.
Is pest treatment around my San Mateo house safe with kids and a dog in the yard?
We will tell you the material, where it went and the re-entry interval before we start — ask, and the technician will walk you through it on site. Most residential work here is targeted to entry points, harborage and the exterior perimeter rather than broadcast across lawns and play areas, which limits exposure by design. Rodent bait stations are tamper-resistant and placed where a dog cannot work them open.
My San Mateo condo has ants coming from the neighbor's unit — what can be done?
Treating your unit alone rarely holds in attached construction. Argentine ants travel through shared wall cavities, plumbing chases and slab edges, so the trail usually crosses several units while the nest sits outside all of them. We treat what is reachable inside your unit, then work with the HOA or property manager on the exterior and common areas, because that is where the population actually lives. Written findings help that conversation move.
