The sink is one point in a connected area
A roach beneath a sink may be close to water, food residue, and narrow hiding places. Activity there does not establish its source or the species. An inspection should connect the visible finding with accessible spaces around the cabinet and nearby equipment. The useful question is where the pest is being sustained, not just which surface the latest insect crossed.
A spotless counter can leave another resource untouched
Conditions behind or beneath equipment can differ from those in the open room. A known leak or inaccessible food residue may remain relevant even when everyday cleaning is thorough. Control and correction of those conditions work on different parts of the problem. This avoids blaming the household or assuming that another general spray alone explains how recurrence will stop.
Evidence should show which areas remain active
Monitoring and location records help interpret changes after work. Repeated small roaches around a kitchen appliance may present a different situation from an occasional visitor beside an exterior door. Species and life-stage identification make that distinction more useful. Call Anderson Pest Control with the kitchen pattern, any known water issue, and what changed after earlier treatment so the assessment can follow the remaining activity rather than start again from a single sighting.
