Warm weather brings more opportunities to spend time outdoors—and more exposure to mosquitoes. While most mosquito bites cause only temporary itching and irritation, mosquitoes can also spread illnesses. In Connecticut, mosquito-borne diseases of concern include West Nile virus and eastern equine encephalitis.
The best protection is prevention. According to the Connecticut Department of Public Health, reducing mosquito breeding areas and protecting yourself from bites can lower your risk.
Eliminate Standing Water Around Your Home
Mosquitoes lay their eggs near water. Even a small amount of standing water can become a breeding site, so one of the most effective ways to reduce mosquitoes around your home is to regularly empty, clean, cover, or remove items that collect water.
At least once a week, check your property for water collecting in:
- Buckets, watering cans, and wheelbarrows
- Flowerpot saucers and planters
- Children’s toys and wading pools
- Birdbaths and pet water bowls
- Tarps, pool covers, and outdoor furniture
- Clogged gutters and drains
- Trash cans and recycling bins
- Tires and other containers that are stored outdoors
Empty and scrub containers before refilling them because mosquito eggs can remain attached to their sides. Keep swimming pools properly maintained and circulating, and tightly cover rain barrels and other water-storage containers.
Visit the CDC’s mosquito control guidance for additional steps you can take inside and outside your home.
Use an Effective Insect Repellent
When spending time outdoors, use an insect repellent registered by the U.S. Environmental Protection Agency. EPA-registered repellents have been evaluated for safety and effectiveness when used according to the product label.
Effective active ingredients may include:
- DEET
- Picaridin
- IR3535
- Oil of lemon eucalyptus
- Para-menthane-diol
- 2-undecanone
The EPA’s online repellent search tool can help you choose a product based on the insects you need protection from and the amount of time you plan to spend outdoors.
Always read and follow the product label. Apply repellent only to exposed skin or clothing, as directed. Do not spray repellent directly onto your face. Spray it onto your hands first, then carefully apply it while avoiding your eyes and mouth.
Adults should apply repellent to children and avoid applying it to their hands, eyes, mouth, or irritated skin. Products containing oil of lemon eucalyptus or para-menthane-diol should not be used on children younger than 3 years old.
More information about choosing and safely applying repellent is available from the CDC’s mosquito-bite prevention resources.
Create Additional Barriers Against Bites
Mosquitoes can bite during both the day and night. When mosquito activity is high:
- Wear loose-fitting long sleeves, long pants, and socks when practical.
- Repair holes in window and door screens.
- Keep doors closed or use air conditioning when available.
- Use mosquito netting to protect infants or when sleeping outdoors.
- Follow local mosquito activity and public-health advisories.
Information about mosquito-borne illnesses and prevention in Connecticut is available through the Connecticut Department of Public Health. Residents can also learn more about West Nile virus in Connecticut.
A quick weekly inspection of your property, combined with proper use of insect repellent, can help reduce mosquito activity and make outdoor activities safer and more comfortable throughout the season.
