Information on Mosquito Control
Breeding Habitat Source Reduction
One of the most effective ways to control mosquito populations that
transmit disease is to reduce the number and types of mosquito breeding
habitats in your community. All mosquitoes require a water source to lay
their eggs, which in the hottest part of summer can hatch into larvae within
a week. To effectively reduce larval hatching, check your property and your
neighborhood for the following common potential residential mosquito
breeding sites:
Fountains, Birdbaths and Water Gardens
- These outdoor reservoirs can provide ideal habitat for breeding
mosquitoes. Replace water in birdbaths and fountains at least twice a
week. Mosquito larvicides are available at many garden centers for
consumer use and can be used in water gardens and fountains without
harming other living things. Certain species of goldfish and
freshwater minnows that eat mosquito larvae can be used in fountains
and water gardens.

In Wisconsin, you need a permit from the
Department of Natural Resources (DNR) in order to use larvicides in
ponds, lakes, rivers and streams. Contact your nearest DNR service
center and ask to speak with the regional aquatic habitat specialist
for more information. |
Tires
-
Tires are especially notorious mosquito breeding
sites. They should be properly discarded, covered or stacked in a shed
or garage so that they cannot fill with water. If you have a tire
swing, make a hole in the bottom of it to allow water to drain out.
Flower Pots, Garbage Cans, and Recycling Bins
- These are found in every yard, and can hold enough water to breed
mosquitoes. Drain dishes under flowerpots every few days and after
rainstorms or move them inside.
- Cover outdoor trash and recycling cans with tight-fitting lids.
Faucets and Air Conditioners
- Remember that they can leak and form puddles that may provide
mosquito breeding habitat. Eliminate any standing water in puddles.
Rain Gutters and Spouts
- Gutters and downspouts need to be kept clean and maintained. Leaves
and other debris can create pools of water and an ideal environment for
mosquito larvae.
Animal Watering Troughs
- These should be flushed at least twice a week to prevent them from
becoming a breeding site.
Leaves and Debris
Clean up leaves and yard debris from low-lying areas to reduce
stagnant water pools.
Plastic and Canvas Tarps
- These are commonly used to cover log piles, boats, and pools, and
they can hold enough water to breed mosquitoes. Make sure water does
not collect in tarps used outdoors.
Wheelbarrows, Tubs, Wading Pools and Boats
- These should be stored upside down or under cover when not in use.

mosquitoes can breed or wish to report a site you think may constitute a
breeding site for mosquitoes, contact your local
public health agency.
