Check whether the pest control company documents what they treated and why.

Start by asking the technician to show a treatment map that labels all inspected and treated zones around the structure and on the lawn. A clear map should include roof eaves, foundation perimeters, entry points, crawl spaces, garage interiors, patios, and the lawn perimeter; if the company refuses to produce this, treat that as a red flag. Request a written report after each visit that lists products applied, active ingredients spelled out, application rates, and the exact locations treated so you can track consistency over time. Insist on seeing both base treatment details and lawn perimeter or turf applications because pests use both the structure and yard to move and breed. Schedule a follow up evaluation visit at a set interval, ideally within two to four weeks after initial treatment, so the technician can assess reduction in activity and adjust tactics if necessary. Ask for quantitative before and after observations such as trap counts, visual sighting logs, or percent reduction estimates rather than vague statements that the site looks better. When unfamiliar terms appear in reports ask for plain language explanations and for the technician to describe what success looks like for your property and timeline for results.

Common problems start with incomplete coverage where only visible areas are sprayed leaving voids under siding or gaps in the lawn; the fix is to insist on a treatment map and a technician who demonstrates those areas were addressed. Another frequent issue is lack of documentation about what product was used and at what concentration which can hide underdosing or inappropriate chemistry; demand written product names and active ingredient concentrations and do not accept generic statements like we used a spray. Finally, inconsistent follow up evaluations cause lingering populations to rebound; require scheduled evaluation visits and simple measurable metrics such as trap counts or sighting logs so adjustments are evidence based.
