Reviews
What customers say
Several positive customers describe pest problems easing after service. One says spiders nearly disappeared and ants became occasional after an initial indoor visit and continuing service around the house; another says earlier spider and wasp issues were resolved. Two customers also recount difficult experiences: one says a technician was rude and that they asked him to leave after he said he could spray despite saturated, puddled grounds; another says the company wanted extra payment for callback pest problems and refused to end the contract.

Frequently Asked Questions
Does Cornerstone Pest Management treat termites or mosquitoes?
No. It refers termite control to a specialist and directs mosquito questions toward standing-water removal and the local mosquito abatement district.
How does Cornerstone Pest Management plan commercial service?
Commercial programs start with a free on-site inspection. Cornerstone schedules service around business hours, documents each visit and keeps the same technician on the route.
Does a regular exterior treatment require customer preparation?
Most regular exterior visits require no action from the customer. For a planned interior treatment, the technician provides any short re-entry times in advance.
What precautions does Cornerstone Pest Management describe for children and pets?
The company says technicians apply products according to EPA labels and explain precautions; typical guidance is to keep children and pets off treated exterior areas until dry. It says treatments can be adjusted for pets, koi ponds, gardens or sensitivities.
How soon does Cornerstone Pest Management schedule service?
The company says it runs daily routes across the Valley and that scheduling is usually quick; it tries to prioritize urgent problems.
