Nex Pest Control's Cockroach Control technicians track egg casings (oothecae), not just live insects, because a treatment that misses the casings just means a second wave in three weeks.
A technician traces roach activity back to the actual harborage point — usually near a water source — before recommending anything.


Every technician treating San Mateo properties for cockroaches carries state pest-control licensing and full liability coverage.
Most San Mateo cockroach calls get a technician out same-day, since roach populations compound quickly once established.
You'll get one flat quote after inspection covering the initial treatment and the scheduled follow-up — no per-visit surprises.
We use gel bait stations, IGR (insect growth regulator), and sticky monitors to track population decline visit over visit.
We treat plumbing chases and appliance motor compartments directly, since that's where German roach populations actually breed.
Larger American cockroaches typically enter through drains, sewer lines, and basement gaps, so treatment includes drain-area gel placement and exterior perimeter barrier.
A single spray kills visible roaches but leaves the ootheca intact — our protocol specifically targets the full life cycle, not just adults.
We service commercial kitchens on off-hours schedules with sealed bait placements that meet food-safety handling requirements.
Injection treatment goes into wall voids and cabinet joints where a surface spray never penetrates.
A second visit two to three weeks out confirms the colony is declining and adjusts bait placement if needed.

Describe what you're seeing — daytime activity, kitchen or bathroom clusters — and we prioritize San Mateo roach calls for same-day slots.
A technician reaches your San Mateo property with gel bait, IGR, and monitoring tools already stocked for roach-specific treatment.
We trace harborage points, identify German versus American species, and quote a flat price before opening a single bait tube.
Guarantee coverage means if roaches are still active after the follow-up window, we return and re-treat at no charge.
Seeing roaches in the kitchen at night was bad enough, but finding them in daylight was what made me call. One visit and the gel bait cleared it out within two weeks.
As a kitchen manager, I needed something discreet during service hours. Their placements are basically invisible to customers.
Roaches kept coming back every few weeks no matter what I sprayed myself. Turns out the egg casings were surviving — the IGR treatment finally broke the cycle.

No matter which San Mateo neighborhood you're in, a technician equipped for cockroach-specific treatment can reach you the same day.

A DIY spray also drives roaches deeper into walls rather than eliminating the harborage, which is why professional gel and IGR placement works differently.
Yes — German and American roaches are naturally nocturnal, so daytime activity usually means the population has outgrown the hidden harborage space.
Most San Mateo clients notice fewer sightings within the first week, though full clearance depends on infestation size.
Our Cockroach Control products are labeled for residential and commercial kitchen use when placed correctly, which our technicians handle directly.
Yes — commercial Cockroach Control service adds recurring monitoring and paperwork that a one-time residential visit doesn't need.
If the follow-up inspection shows lingering activity, we return and re-treat the identified harborage points at no extra cost.
