Interview Questions to Ask a Pest Control Technician Candidate
Questions that surface real evidence of treatment expertise, safety compliance, and customer trust in people's homes — plus what to actually listen for in the answer, not just whether they say the right buzzwords.
1. How do you identify what pest is causing a problem and decide on a treatment plan for a home?
What to listen for: Look for inspecting for evidence, correctly identifying the pest, understanding its habits, choosing the least risky effective treatment, and giving the customer prevention advice.
2. A customer with small children and a pet asks you to spray every room. How do you respond?
What to listen for: Expect following the product label, using targeted and low-risk methods where possible, explaining precautions and re-entry times, and refusing unnecessary or unsafe applications.
3. You realise you applied a product to the wrong area of a property. What do you do?
What to listen for: The candidate tells the supervisor and customer promptly, takes steps to limit exposure, follows reporting procedures where required, and learns from the error honestly.
4. A customer calls three times saying the pests are back right after treatment. How do you handle the visit?
What to listen for: A good answer involves listening, rechecking for the source and entry points, explaining the pest's life cycle, and being honest about what the treatment can and cannot do.
5. What would you do in your first 30 days in this pest control technician role?
What to listen for: Whether their plan is grounded in the role's actual must-haves (pest identification and pesticide application) or generic ("get to know the team"). Specificity here signals real understanding of the job, not just interview prep.
6. Why are you leaving your current role, and why this one specifically?
What to listen for: Forward-looking motivation tied to something concrete about this role, versus badmouthing a past employer or vague dissatisfaction. Watch for whether their reasons actually match what this role offers.

Frequently asked questions
How many of these questions should I ask in one interview?
3-4 is realistic for a 30-45 minute interview once you leave room for follow-ups and the candidate's own questions. Divide competencies across panel members rather than every interviewer asking all of them — see the Interview Scorecard tool for a structured version of this.
