These flying pests are annoying with a bite that can be anywhere from mildly irritating to seriously painful. AND they can transmit disease, so it’s a good idea to start with preventing them from breeding. Don’t let mosquitoes breed in your yard! Anything that can hold water for more than five to seven days can produce mosquitoes. Fountains and bird baths, potted plant saucers, water bowls for pets and rot holes in trees are just a few examples where small amounts of water can accumulate. The Marin/Sonoma Mosquito and Vector Control District has good information about Ways to Minimize Mosquitoes Around Your Home along with Personal Protection Measures. It’s also a good idea to know what is a mosquito and what’s not – Insects that Resemble Mosquitoes.
