How did you hear about us?

Welcome to Mosquito Joe of St. Charles County

If you live in Missouri then you know that mosquitoes here are no joke! Mosquitoes have a tendency of ruining outdoor fun and they also expose us to insect-borne disease. Lucky for you, Mosquito Joe of St. Charles County has you covered, offering a variety of services so you and your family can enjoy the outdoors. Whether you are looking to have us keep your yard itch-free all summer or planning a special outdoor event, we have the right service for you. We've dealt with a wide array of yards and know exactly what to look for, making sure to not only eliminate the mosquitoes you already have, but to also identify and remove any places that mosquitoes could breed or live.


Mosquito Joe provides mosquito control solutions for residential and commercial properties. Our Missouri licensed technicians come to your yard every 21 days and not only treat your yard, but work to reduce the number of larvae and eggs on your property too. We don't believe in contracts here at Mosquito Joe and think our product will speak for itself. Don't believe us? See what others are saying about our services! Here are a few of our most popular treatments:

  • Flea Control: In addition to our mosquito control services, we offer flea control services to help protect your furry friends. Let Mosquito Joe of St. Charles County be your first line of defense against these disease-carrying pests.
  • Tick Control: Pet owners and parents alike are concerned with tick prevention. To help mitigate that concern, our technicians create a barrier for these intruders to prevent serious complications like Lyme disease.
  • Special Events: Whether you're celebrating your child's birthday or entertaining some friends, we will make sure that your party guests enjoy your yard in a bite-free environment.

It's a bit too soon to offer up a 10, but a good 8 based on the fact that I've only had 2 treatments so far. The 2nd treatment was on 6/13 and we spent a good amount of time out back after dusk which is typically the worst. I got a couple bites and had a couple mosquitos around me and so did a friend, but it certainly would've been worse had we not been treated at all. Anyway, it's just too soon to confirm either way. Ask me again later in Summer.

We've already recommended you to several of our friends. Andrew is a great guy, too, and that always makes me even more likely to recommend.

Price seemed kind of expensive for my very small yard. Kept the mosquitos away for several weeks but might just try some yard spray cans next time.

The efficient use of email to alert, complete and invoice service! The attention to weather detail, i.e. no wasted applications due to rain. It WORKS!
