Inspection-First • Evidence-Based • Guaranteed Results
Most pest exterminator calls in Castro Valley, CA follow the same arc: technician arrives, applies a general spray, hands over a service report, leaves. Homeowner feels better for two weeks. Then the problem comes back — sometimes worse — and the cycle starts again.
M & K Pest Control was built on a different premise. Every pest problem has a source. Every infestation has a reason it established where it did. Finding that reason — and treating it — is the difference between a service call and an actual solution.
We don't apply product before we inspect. We don't recommend treatment before we understand what we're treating. What you get from M & K is an exterminator who knows the difference between a German cockroach infestation and an American cockroach intrusion, why that difference changes every product and placement decision, and how to communicate all of that to you in plain language before we do anything.
That's what professional pest extermination looks like in Castro Valley.

A homeowner in Castro Valley, CA had experienced recurring cockroach activity in the kitchen for four months despite two treatments from a prior pest control company.
German cockroach infestation with established harborage inside the stove assembly, refrigerator motor housing, and wall void behind the sink plumbing.
Activity declined visibly by day 10. Full elimination confirmed at day 30. Zero activity at 90-day check-in.
