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. Cogent always does a good job treating our house for bugs, and they've helped us out when we have had situations come up.  Just the other day, I brought home bedbugs from a hotel stay, and Michael spent some time on the phone talking me through first steps that I can take myself.  He wanted to help me without selling me an expensive service.  I would definitely recommend!

 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.
