Our Services

Pests don't stand a chance.

Traditional Mosquito Control

Mosquito Squad's most popular mosquito control service, our traditional barrier spray will decrease your yard's mosquito population by 85-90%! Our trained technicians treat key areas of your property, eliminating adult mosquitoes on contact and providing continuous protection, reapplying every 2-3 weeks.

All Natural Mosquito Control

Mosquito Squad's all natural mosquito spray is made up of essential oils, eliminating adult mosquitoes on contact and repelling 70-75% of your property's mosquito population. As opposed to our traditional barrier protection, the all natural treatment must be applied every 14 days.

Intensive Tick Treatment

For the most comprehensive tick control, our technicians utilize a combination of our traditional barrier spray and tick tubes. Our barrier spray will eliminate adult ticks on contact while tick tubes are placed in key areas on your property, twice a season, to eliminate ticks at their nymph stage.

Automatic Misting System

Mosquito Squad's mosquito misting system is installed on your property for continuous control, all season long. The system automatically delivers a 30-second spray 2-4 times a day when mosquitoes are known to be at their most active.

Special Event Spray

From outdoor weddings to backyard barbecues, our special event spray keeps your guests off the menu. Our trained technicians will spray the area before the event, creating an odorless barrier, eliminating mosquitoes.


Satisfied customers: The strongest proof of our performance

Our kids hate getting bug bites when playing outside. But now Mosquito Squad allows our entire family to enjoy more time outdoors.

We had a Mosquito Squad misting system installed last summer and it has made a huge impact on our backyard. Our 11 year old, who was constantly bitten by bugs, now can play all day without one bite. He raves about it to all his friends in the neighborhood. It’s great for families who want to enjoy their outdoor space.

We called Mosquito Squad last summer when our yard became inundated with mosquitoes. Not only has it allowed us to spend more time outdoors without bug bites, but their service has been wonderful. They call us before and after every spray so we don’t have to worry when we are due or if they’ve been there.

I used Mosquito Squad last summer and couldn’t have been happier! I live on a wooded lot connecting to a creek and common ground. I have a lot of wild critters around that I thoroughly enjoy. I also have three dogs that like to be out. It was wonderful to spend a whole summer not only with no mosquito issues but no ticks either! I highly recommend Mosquito Squad and their services to all my St Louis friends and neighbors!!!
