Cogent Pest Elimination was quick to respond. They were the first company I spoke to that didn’t feel like they were overpriced and who wasn’t booked out a month. I was able to have the hornets treated within 48hr of my call. I would highly recommend

 Trustindex verifies that the original source of the review is Google. Anyone can use a sprayer. But if you want your home treated by someone who has the knowledge behind what to spray and why Cogent is the best choice.  They've treated my homes for ten years. Always energetic and professional and careful of my small dog. I depend on Cogent to keep our place safe. I started with them because I didn't want pest "control", I wanted pest elimination.

 Trustindex verifies that the original source of the review is Google. First time using Cogent Pest Elimination and was very pleased. We had an ant problem in our kitchen and my baking room. Michael checked the home and found the colony where they were coming into our home. He sprayed, baited kitchen and applied granular  which was safe for dog not to be harmed by. Promised to come back the following week if we saw any more ants. So far so good. We will be calling on them again should the need arise.

Common Questions From
Homeowners

Whether you’re dealing with an active pest issue or simply exploring your options,
we’re here to provide clear answers and honest recommendations.

Do I need a long-term contract?maazh2026-06-24T15:53:23-08:00

Do I need a long-term contract?

No. Most of our residential services are provided without long-term contracts. We believe you should continue working with us because you’re happy with the service—not because you’re locked into an agreement. (Some specialty services, such as termite protection, may require ongoing monitoring.)

How quickly can someone come out?maazh2026-06-24T15:54:56-08:00

How quickly can someone come out?

It depends on where you’re located and the type of issue you’re experiencing. If you’re in one of our regular service areas, we can often respond very quickly. When you call, we’ll let you know the earliest available appointment and work to get someone out as soon as possible.

What pests do you treat?maazh2026-06-24T15:55:14-08:00

What pests do you treat?

We handle most common household pests throughout the St. Louis area, including ants, spiders, wasps, hornets, carpenter ants, silverfish, centipedes, earwigs, and many other nuisance insects. If you’re not sure what you’re dealing with, we’ll help identify it and recommend the right solution.

Is your treatment safe for children and pets?maazh2026-06-24T15:55:30-08:00

Is your treatment safe for children and pets?

Every situation is different, which is why we take the time to explain exactly what we’re using and any precautions you should take. We apply products responsibly, follow all label directions, and tailor our approach to your home and family.

Will the pests come back?maazh2026-07-27T05:29:56-08:00

Will the pests come back?

Our goal isn’t just to reduce activity for a few days, we want to solve the underlying problem. That means identifying why pests are there in the first place and addressing the conditions that allow them to return. Depending on the pest, treatment, and property, we may also recommend follow-up visits, preventative treatments, or a combination of both.

Do you offer warranty programs?maazh2026-07-27T05:21:36-08:00

Do you offer warranty programs?

Yes. Our quarterly service customers receive priority pricing and a limited service warranty. If pest activity returns, follow-up visits may be available depending on the pest, treatment, and nature of the problem. We will clearly explain what is covered before service begins, so you know exactly what to expect.

What if I’m not sure what’s causing the problem?maazh2026-06-24T15:57:18-08:00

What if I’m not sure what’s causing the problem?

That’s exactly why we’re here. Whether you’ve seen one ant or think you might have a larger issue, we’ll help determine what’s happening, answer your questions honestly, and recommend the next best step—even if that means you don’t need a service right away.

Will I speak to someone local?maazh2026-06-24T15:56:59-08:00

Will I speak to someone local?

Yes. When you call Cogent, you’re speaking with the owner directly that understands the pest problems common to the St. Louis area. You won’t be routed through a national call center or an answering service.
