Mosquitoes in Missouri: Facts, Treatment, & Prevention

If you’ve spent any summer in Missouri, you know mosquitoes can quickly turn a relaxing evening on the porch into a battle against itchy bites. These buzzing pests aren’t just annoying—they can also carry serious diseases.

Whether you’re in St. Louis, St. Charles, or out in the countryside, understanding how to control mosquitoes around your home is key.

In this guide, you’ll learn the facts about mosquitoes in Missouri, how to treat mosquito-prone areas, and what you can do to prevent future infestations.

Key Takeaways

• Most mosquitoes in Missouri are harmless, but some spread diseases like West Nile virus, dengue, and heartworm in pets.
• Standing water in birdbaths, rain barrels, gutters, and old tires gives mosquitoes places to lay eggs and grow quickly.
• Removing water weekly, fixing drainage, and using mosquito repellent with DEET are easy ways to protect your yard.
• Monthly mosquito control with fogging, In2Care stations, and a re-treat guarantee keeps mosquitoes away through the summer.

Common Types of Mosquitoes in Missouri

There are over 50 species of mosquitoes in Missouri, but only a few cause problems for homeowners. One of the most aggressive is the Asian tiger mosquito, easily recognized by its black-and-white striped body. Female mosquitoes, which are the ones that bite, need a blood meal to lay eggs.

Some common mosquito-borne illnesses in Missouri include:

• West Nile Virus
• Zika Virus
• Dengue
• Yellow Fever
• Encephalitis
• Heartworm (in pets)

These diseases are spread through mosquito bites, typically from adult mosquitoes that have picked up the virus from infected birds or mammals.

Where Do Mosquitoes Breed?

Mosquitoes lay eggs in standing water, and it doesn’t take much—even a bottle cap full can do the trick.

Around Missouri homes, common breeding sites include clogged gutters, birdbaths, old tires, flowerpots, rain barrels, tree holes, puddles, and low-lying areas with floodwater or stagnant water.

These spots support every stage of the mosquito life cycle. Eggs are laid on the water surface, followed by mosquito larvae in the larval stage, then mosquito pupae in the pupal stage, and finally adult mosquitoes that emerge to seek out a blood meal and start the cycle again.

DIY Mosquito Prevention Tips

You can take several simple steps to help control mosquitoes on your property:

• Empty water from flowerpots, birdbaths, old tires, and rain barrels weekly.
• Keep gutters clean and draining properly.
• Fix yard drainage to avoid puddles and floodwater collecting.
• Use EPA-approved mosquito repellent with DEET when spending time outside.

There are also natural repellent options like oil of lemon eucalyptus, but always read labels to make sure it’s safe for you and your family.
