Reducing Mosquitoes
How can we reduce the number of mosquitoes in our outdoor learning environment?
Most important – eliminate standing water
- Clear roof gutters of leaves and debris that prevent water from draining properly. Gutter guards can help prevent leaves and debris from clogging gutters and downspouts.
- Repair leaky outdoor faucets.
- Water in birdbaths should be changed at least twice a week.
- Empty or discard containers that can hold standing water.
- Rain barrels and cisterns should have screens to keep out mosquitoes.
- Correct drainage problems that cause water to pool.
- Remove debris or report drainage problems in ditches and culverts.
Attract bats and dragonflies
One small brown bat can catch 600 mosquitoes per hour and dragonflies have earned the nickname “mosquito hawk” due to their appetite for mosquitoes. To attract bats, build or buy a bat house. For information about building and installing a bat
house, go to Bat Conservation and Management. Because dragonfly larvae are aquatic and adults must live near a body of water, dragonflies are a good option if you have an existing body of water.
Include mosquito-repelling plants
Examples include:
- Basil
- Catnip
- Lavender
- Lemon Balm
- Lemon Thyme
- Lemon Verbena
- Marigolds
- Rosemary

Wear light colored, loose fitting clothing
Mosquitoes are attracted to dark clothing and some can bite through tight-fitting clothes. When practical, wear long sleeves and pants.
Do not wear scents
Do not wear perfumes or scented soaps, deodorants, lotions, etc.
Make use of fans
An anchored fan, secured and out of the children’s reach, can help keep mosquitoes away and provide a cooling breeze .
