A proper inspection should connect the pest sightings to specific conditions around the property. For ants, that might mean a trail leading to an aphid-infested shrub or a gap beside a door. For roof rats, it could be a damaged vent screen or overhanging branches providing access to the roof. Mosquito investigations should focus on standing water, containers, and drainage problems. Ask the residential pest control technician to identify the pest, explain the evidence supporting the assessment, and distinguish necessary repairs from any proposed pesticide treatment. The findings should guide the response rather than lead to the same treatment for every pest sighting.
