Cockroach Elimination
Cockroach Control in Hollister, CA
101 Exterminators does cockroach control in Hollister for homes, apartments, and the restaurant kitchens along San Benito Street. German cockroaches (Blattella germanica) are the ones that establish here, and they arrive in cardboard, in used appliances, and in deliveries — not through the front door, and not because of housekeeping. We identify the species, bait the harborage, and come back to verify. CA licensed, SPCB Lic. #9119.
Warning Signs
Signs You Need Cockroaches Service in Hollister
Species-specific treatment using gel baits, insect growth regulators (IGRs), and targeted void treatments. Gel bait is placed directly at harborage sites — behind refrigerators, under sinks, inside wall voids — where cockroaches consume and transfer it to others in the colony. IGRs prevent juvenile cockroaches from reaching reproductive maturity, collapsing the population within 2–4 weeks. Commercial kitchen programs include written documentation of conducive conditions for health inspection compliance.

How It Works
Our Cockroaches Process in Hollister
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in Hollister.
Inspection & Species ID
We identify the cockroach species and locate all harborage sites — behind refrigerators, under sinks, inside wall voids, and in any warm, dark area near moisture or food. Species identification determines the correct bait and treatment approach.
Bait Application
Gel bait is placed at harborage sites in quantities cockroaches will find and consume. Bait is formulated to be transferred between individuals — a single fed cockroach will infect others in the colony, reaching the full population.
IGR Treatment
Insect Growth Regulators (IGRs) prevent juvenile cockroaches from reaching reproductive maturity, collapsing the population within 2–4 weeks even without direct contact with adults.
Exclusion & Prevention
We identify and seal gaps around plumbing penetrations, appliances, and wall voids that provide harborage. For commercial kitchens, we provide a written report of conducive conditions for health inspection compliance.

Common Questions
Cockroach Control FAQs for Hollister
We keep a clean kitchen in Hollister. How did we end up with cockroaches?
Most German cockroach infestations start with something carried in — a cardboard box, a used appliance, a grocery or supply delivery, a piece of furniture from another building. Cleanliness affects how fast a population grows, not whether it arrives. In shared-wall buildings downtown they also simply walk through the plumbing chase from the next unit. Finding them says nothing about the household, and the first step is identification, not scrubbing.
Big roaches come up in the bathroom of our old Hollister house after it rains. Are those German cockroaches?
No — those are almost certainly American cockroaches (Periplaneta americana), which live in drains, sewer laterals, and damp crawl spaces rather than kitchens. Winter rain in Hollister pushes them out of the lines, and older raised-foundation houses give them easy access through unsealed penetrations. The fix is different too: drain and crawl-space work, sealing penetrations, and moisture correction rather than kitchen baiting.
Can an apartment in a downtown Hollister building be treated one unit at a time?
It can be attempted, but in Hollister's older downtown buildings it rarely holds. Those apartments were carved out of late-1800s and early-1900s structures, and shared plumbing chases plus decades of fault settling leave openings German cockroaches cross freely. Treatment that works covers the affected unit plus the units beside, above, and below it, with monitors left in place afterward to show whether anything is still moving.
