Water Gardens and Mosquitoes

Mosquitoes can easily reproduce in standing water, so gardeners who have water gardens should take steps to keep these pesky insects in check.

If you have a small container garden, just add water to the container until it flows over the top and flushes out the mosquito larvae. Installing a pump in a larger water garden will circulate the water and make it less attractive to mosquitoes.

Another option is to add fish. Gambusia are small native fish that feed on mosquito larvae and pupae at the water's surface.

Or you can buy mosquito dunks. These donut-shaped products gradually release the bacterium Bti (Bacillus thuringiensis israelensis) that kills mosquito larvae but is safe for plants, pets, and the environment.
