How to Hire a Pest Control Company: What Every Homeowner Should Ask
Published August 04, 2026 · ZipServ
In North Texas, pest control isn't a luxury — it's year-round maintenance. Fire ants, cockroaches, termites, mosquitoes, and rodents are active almost all twelve months. The right pest control company handles problems before they escalate; the wrong one treats symptoms while missing the source.
The most important question: are they licensed?
In Texas, anyone applying pesticides for hire must be licensed by the Texas Department of Agriculture (TDA). Pest control technicians must hold a Commercial Pesticide Applicator License. Ask for the license number and verify it through TDA. An unlicensed applicator isn't covered if something goes wrong — and improperly applied chemicals around children or pets can be dangerous.
1. What pests are included in your treatment plan?
General pest control plans typically cover ants, cockroaches, spiders, and crickets — but may not include termites, mosquitoes, or rodents. These are usually separate service agreements with different pricing. Know exactly what's covered before you sign.
2. What products do you use?
You have the right to know what's being applied in and around your home. Ask for the product name and SDS (Safety Data Sheet). Reputable companies use this as a selling point, not a secret. If you have children, pets, or a garden, ask specifically about those areas and what protocols they follow.
3. Is the initial treatment and follow-up included?
Most pest control starts with an intensive initial treatment, then quarterly follow-up visits. Understand what happens between visits — is re-treatment free if you see activity 2 weeks after a visit? The answer should be yes.

4. Interior vs. exterior-only treatment?
Some companies only treat the exterior perimeter; others also treat inside. For cockroach or rodent problems especially, interior treatment is often necessary. Clarify what's included so you can compare quotes apples-to-apples.
5. Do you offer a termite inspection?
In DFW, subterranean termites are the most damaging pest most homeowners will face. Ask whether termite inspection is included in their service or available separately. Treatment for active termites is different from general pest control.
6. What's the contract commitment?
Annual contracts with quarterly service are standard in pest control. Understand the cancellation policy before signing. A 30-day cancellation window with no fee is reasonable; a 6-month penalty for leaving is not.
Red flags
- Can't provide a TDA license number
- Refuses to disclose what products they're applying
- Quotes a price for a job they haven't inspected
- Door-to-door solicitation with high-pressure tactics and "limited time" offers
- No written service agreement
Pest control effectiveness is often invisible until it fails — you don't notice the ants that didn't come in this summer. That's why neighbor recommendations matter more here than in almost any other service category. Someone who's had a company protecting their home for three years with zero re-infestations is telling you something a five-star review can't.
