A pest control technician comes to your home, spends 20 minutes, leaves a bill, and drives away. Was that effective? Is the problem getting better? Should you renew the quarterly contract?
Most homeowners have no framework for evaluating pest control service quality. Here's what separates a good technician from one who's just going through the motions.
1. They inspect before they treat. A good technician spends as much time inspecting as treating — often more. They're looking for entry points, harborage areas, moisture sources, and signs of specific pest activity. If the technician walks in and starts spraying without inspecting, that's a red flag.
2. They tell you what they found and what they did. After service, you should receive a written report or verbal explanation: what pests they found, where they found them, what they applied, and what you should do between visits. If you don't know what happened after they leave, the service has no value.
3. They make specific recommendations. "You have a moisture problem under the sink that's attracting cockroaches — fix the leak and they'll decline faster." A good tech doesn't just treat symptoms — they identify root causes and tell you about them. This is IPM in action.
4. They use targeted products, not broadcast sprays. A technician who walks the perimeter with a spray wand and nothing else is providing the lowest-value service possible. Quality service includes gel bait in cracks, dust in voids, and targeted applications to specific harborage areas — not just baseboard spray.
5. Your pest problem is actually improving. This seems obvious, but many homeowners continue paying for quarterly service while the problem persists. After 2–3 visits, you should see measurable improvement. If cockroach counts aren't declining after 6 weeks of professional treatment, something is wrong.
1. The visit takes less than 15 minutes. A thorough residential treatment takes 30–60 minutes for a standard home. A 10-minute visit means the tech is spraying baseboards and leaving. This is the pest control equivalent of a mechanic glancing at your car and declaring it fixed.
2. They only spray — no bait, no dust, no monitoring. Spray-only service is the cheapest and least effective approach. Professionals use gel bait for cockroaches, dust for voids, and monitoring devices to track progress. If your tech's entire toolkit is a spray wand, you're paying for the appearance of treatment, not actual control.
3. They can't tell you what product they used. You have the legal right to know what pesticides were applied in your home. A professional should provide product names, active ingredients, and safety information. If they can't or won't answer, that's a regulatory compliance issue.
4. They pressure you into long-term contracts before diagnosing the problem. A reputable company diagnoses first, recommends treatment, and then discusses ongoing service if appropriate. Pressure to sign a 12-month contract before the first inspection is a sales tactic, not pest management.
5. They guarantee "complete elimination" of outdoor pests. No one can guarantee elimination of outdoor mosquitoes, ants, or spiders. They can reduce populations significantly. Any company guaranteeing complete outdoor pest elimination is making promises they can't keep.
