Precision Treatment That Eliminates the Infestation at the Source
CLICK HERE TO CALL (877) 905-2885Seeing cockroaches during the day is a specific data point, not a general observation. Cockroaches are nocturnal. When they appear in daylight — running across a counter, fleeing from under the refrigerator when the light comes on — it means the population inside the harborage zones has grown dense enough that subordinate individuals are being forced out into exposed space.
You're not seeing the beginning of a cockroach problem. You're seeing the visible surface of one that's already established.
M & K Pest Control provides cockroach exterminator services in Portola Valley, CA with the diagnostic precision that situation requires: species identification before any product decision, harborage zone mapping before application, and treatment protocols matched to the specific infestation — not to a standard roach spray category.
The cockroach that's infesting your kitchen in Portola Valley and the one coming through your floor drains are not the same pest. They are not treated the same way, and applying the wrong treatment to the wrong species produces poor results at best and an expanded infestation at worst.
