Pest Control in Concord, CA
Clark Pest Control handles residential and commercial pest control across Concord and central and eastern Contra Costa County, from the Mount Diablo foothills to the edge of the Delta. Our Nelson Avenue branch treats the pests this inland East Bay climate actually produces: Argentine ants that flood kitchens every dry summer, cockroaches in older buildings, roof rats and ground squirrels moving in from open space, and subterranean termites working through the soil under decades-old homes.
Clark has served this area since 1950. Call (925) 222-2505 for a free estimate or same-day help.

About Our Concord Team
Contra Costa County puts its own spin on pest control, and our Concord technicians know it firsthand because they live here. Hot, dry inland summers push Argentine ants indoors in search of water, while the county's older housing stock around downtown Concord, the Monument Corridor, and the established neighborhoods near Todos Santos Plaza gives subterranean termites and cockroaches the aging wood and moisture they look for.
A Smarter Approach for Contra Costa County:
We do not just spray and move on. We lead with Integrated Pest Management (IPM), which means we inspect your foundation, attic, eaves, and entry points first, then place targeted, family-safe treatments where the pests actually travel. It is a cleaner approach that fits the mix of suburban homes, hillside lots, and Delta-edge properties across central and eastern Contra Costa.
Localized Pests We See Every Day:
Our crews handle the pests that show up across Concord and the surrounding cities: spring and summer ant trails, cockroaches in older buildings, ground squirrels and roof rats moving in from open space and creek corridors, spiders in garages and sheds, and the occasional yellowjacket nest along eaves. If you have searched for an exterminator in Concord, this is the team that answers the call.
The Clark Concord Experience:
We respect your time. You get a heads-up before the technician arrives and a clear summary afterward of what we found and what we treated. From central Concord out to Walnut Creek, Martinez, Pleasant Hill, and Pittsburg, you get the same same-day and Saturday responsiveness.

Frequently Asked Questions About Pest Control in Concord
What pests are most common in Concord homes?
Ants, cockroaches, rodents, and termites are the most common pests in Concord homes. Hot, dry inland summers drive Argentine ants indoors looking for water, older buildings near downtown and the Monument Corridor attract cockroaches, ground squirrels and roof rats move in from open space and creek corridors, and subterranean termites work through the soil under the area's older housing stock.
Do you offer same-day pest control in Concord?
Yes, Clark offers same-day and Saturday appointments in Concord whenever scheduling allows. Our Nelson Avenue branch is staffed Monday through Friday from 7 a.m. to 7 p.m. and Saturday from 7 a.m. to 6 p.m., so you can usually get a technician out quickly for an active infestation. Call (925) 222-2505 to check the next available visit.

Do I need an exterminator or a pest control service in Concord?
For most Concord homes, a licensed pest control service is the better long-term choice over a one-time exterminator visit. Clark uses Integrated Pest Management to find and seal entry points and treat where pests actually travel, which prevents repeat problems rather than just knocking down what is visible today. We are licensed by the California Structural Pest Control Board and GreenPro certified by the NPMA.
