Hiring a Pest Control Company? Ask These Questions First

Pest control involves applying chemicals in and around your home, which means the company you hire needs to balance effectiveness against safety for your family, pets, and environment. The cheapest pest control often means the heaviest chemical application with the least targeted approach. Vet any company against this checklist before letting them spray -- the goal is to solve a pest problem without creating a health or environmental one.

8 QuestionsPrintable ChecklistAvg Cost: $100 - $1,500 per treatment

Questions to Ask

1Are you licensed for pest control in this state, and what certifications do your technicians hold?

Why It Matters

Pest control licensing requires passing exams on pesticide safety, application methods, and pest identification. Different pest categories (general pests, termites, wildlife) often require separate certifications.

Red Flag

The technicians are unlicensed or don't hold certifications for the specific pest type they're treating.

Pro Tip

Ask which specific license categories they hold. Termite treatment, wildlife removal, and fumigation typically require additional certifications beyond general pest control.

2What pest did you identify, and how did you determine that?

Why It Matters

Proper identification determines the treatment method. Treating for the wrong pest wastes money and doesn't solve the problem. Different ant species, for example, require different baiting strategies.

Red Flag

They recommend treatment without identifying the specific pest species, or they diagnose without a thorough inspection.

Pro Tip

A quality technician will inspect carefully, identify the specific species, explain where they found evidence, and show you the evidence so you understand the situation.

3What treatment method will you use, and what are the active ingredients?

Why It Matters

You have the right to know what chemicals are being applied in your home. Some treatments are targeted (baits, traps), while others are broad-spectrum (spraying). Targeted methods are generally safer and more effective.

Red Flag

They won't disclose the products they use, or they rely exclusively on broad-spectrum spraying for every pest type.

Pro Tip

Ask for Safety Data Sheets (SDS) for all products used. Integrated Pest Management (IPM) approaches that combine targeted treatments with exclusion and habitat modification are most effective long-term.

4What specific precautions should we take for children and pets, and what are the re-entry intervals for the products you plan to use?

Why It Matters

Children crawl on treated floors and put their hands in their mouths. Cats are especially sensitive to pyrethroids, which are common in household pest control. Dogs eat bait stations. The re-entry interval -- how long before the treated area is safe -- varies from 30 minutes to 24 hours depending on the product and application method.

Red Flag

They claim everything is completely safe with no precautions needed, or they cannot tell you the specific re-entry interval for the products they use.

Pro Tip

Ask for the product labels and Safety Data Sheets. For homes with crawling infants or cats, request gel baits and contained stations rather than surface sprays. A responsible company will discuss product selection specifically around your household composition.

5Do you follow an Integrated Pest Management approach, and what does that look like for my situation?

Why It Matters

Integrated Pest Management (IPM) combines inspection, identification, exclusion, habitat modification, and targeted chemical treatment as a last resort. IPM produces longer-lasting results with less chemical exposure than spray-and-pray approaches.

Red Flag

They have never heard of IPM, or their entire service model is scheduled chemical spraying regardless of whether pests are present.

Pro Tip

An IPM-oriented company will inspect first, identify the species and entry points, recommend sealing gaps and removing food and water sources, and then apply targeted treatment only where needed. This approach costs the same or less and lasts longer.

6If the pests come back after treatment, what is your re-treatment policy and timeline?

Why It Matters

Some pest problems require multiple treatments to fully resolve, especially for established colonies of ants, roaches, or rodents. Knowing whether follow-up visits are included in the original price prevents unexpected charges.

Red Flag

Every return visit is a separately billed service call, or they refuse to guarantee results for any period after treatment.

Pro Tip

For general pest treatment, a 30 to 90 day warranty with free re-treatment is standard. For termites, look for at least a one-year warranty with annual renewal options. The warranty should specify a response time for re-treatment requests.

7For termite treatment, what method are you using -- liquid barrier or bait stations?

Why It Matters

Liquid barrier treatments (Termidor) create a chemical zone around the foundation. Bait stations (Sentricon, Trelona) kill the colony over time. Both work, but they have different costs, timelines, and maintenance needs.

Red Flag

They push one method without explaining alternatives or assessing which is better for your situation.

Pro Tip

Liquid barriers provide immediate protection but may not reach all entry points. Bait stations eliminate the colony but take months to work. Some companies combine both approaches for comprehensive protection.

8Will you provide a written inspection report and treatment plan?

Why It Matters

A written report documents what was found, where it was found, and what treatment is recommended. This is especially important for real estate transactions and for monitoring whether the treatment worked.

Red Flag

They give a verbal assessment and price without any written documentation.

Pro Tip

The report should include: pest species identified, locations of activity, severity assessment, recommended treatment method, products to be used, and follow-up schedule.

Bonus Tips for Hiring a Pest Control

  • Before the technician treats, ask them to show you where they found evidence of pest activity. A quality inspection should identify entry points, nesting areas, and moisture sources -- not just spray baseboards and leave.
  • If you are on a quarterly pest control plan, ask what the technician checks each visit beyond applying product. A good recurring service includes a perimeter inspection, monitoring station checks, and a written report of findings.
  • For wildlife issues (raccoons, squirrels, bats), verify the company holds a wildlife control license separate from their pest control license. Trapping and relocating wildlife requires different permits and expertise than insect treatment.
