Walk me through how you conduct a standard pest inspection for a residential property.
Why they ask: To assess your process, thoroughness and ability to identify issues before treating.
How to structure your answer: Walk-through: start with preparation, then move through internal and external areas, and finish with documentation and recommendations.
Example answer
“First, I review any previous service history and ask the client about what they have noticed. I then inspect externally, checking the perimeter, roof void, subfloor and garden areas for signs of pests, entry points or conducive conditions. Inside, I check kitchens, bathrooms, laundry and storage areas for droppings, damage or live activity. I use a torch and sometimes Termatrac or a thermal imaging camera to confirm termite activity. I record all findings and discuss a treatment plan with the client, including prevention advice.”

Tell me about a time you had to deal with a difficult client who disagreed with your treatment recommendation.
Why they ask: To see how you handle conflict, educate clients and maintain professionalism.
How to structure your answer: STAR: describe the situation, the task, the action you took and the result.
Example answer
“A homeowner wanted an immediate spray for ants in the kitchen, but I had identified a moisture problem behind the dishwasher that was attracting them. I listened to their concerns, explained why treating the source would be more effective, and offered a plan that included fixing the moisture issue and using a targeted bait. They agreed, and the ants were resolved without repeated callbacks. The client later referred me to a neighbour.”

You are treating a restaurant and you notice signs of cockroaches in the kitchen. What do you do?
Why they ask: To test your judgement under pressure and your understanding of food safety and client communication.
How to structure your answer: Judgement under pressure: prioritise safety, inform the right people, document, treat according to regulations, and advise on follow-up.
Example answer
“I would stop and assess the extent of the activity without disturbing food preparation. I would inform the manager immediately, explaining that cockroaches in a kitchen are a food safety risk. I would document what I found, then apply a gel bait or appropriate treatment in cracks and crevices away from food surfaces. I would advise the manager on cleaning and exclusion measures and schedule a follow-up inspection to confirm control.”

How would you identify and treat a termite infestation in a timber-framed home?
Why they ask: To assess your technical knowledge of termite management and compliance with standards.
How to structure your answer: Technical explanation: describe detection methods, confirm species, then outline treatment options and standards.
Example answer
“I would start with a thorough inspection using a Termatrac radar and thermal imaging camera to detect termite activity without disturbing them. I would look for mud tubes, damaged timber and evidence of moisture. Once I confirm live termites, I would identify the species and choose a treatment such as a chemical barrier, baiting system or physical barrier, following AS 3660. I would also recommend addressing any moisture issues and schedule monitoring to ensure the colony is eliminated.”

What steps do you take to handle and apply pesticides safely?
Why they ask: To confirm you know WHS requirements, chemical handling rules and safe work practices.
How to structure your answer: Risk assessment and compliance: list the steps you take before, during and after application.
Example answer
“Before applying any pesticide, I read the safety data sheet and product label, check the application equipment, and put on the required PPE. I secure the area, ensure no people or pets are nearby, and apply the product at the correct rate and method. Afterward, I clean the equipment, store chemicals correctly, and dispose of containers as per regulations. I record the treatment and any safety incidents.”

How do you explain prevention measures to a client who wants a one-off treatment?
Why they ask: To see if you can educate clients and build value beyond a single service.
How to structure your answer: Education and empathy: acknowledge their request, explain the benefits of prevention, and give practical, simple advice.
Example answer
“I would start by acknowledging that they want a quick fix and that the treatment will address the current issue. Then I would explain that pests often return if underlying conditions like food, water or entry points remain. I would give them a few simple steps, such as sealing gaps, fixing leaks and keeping food stored properly. I would offer a follow-up inspection and leave a written summary so they can decide. Most clients appreciate understanding why ongoing management saves them hassle.”
