Does spraying work?


There are many different kinds of mosquitoes, each with its own characteristics and habits. 
In the United States alone, there are 150 different species.
Each species carries different types of diseases and will typically breed and feed at different times of the day.

It is necessary to understand the role that different species play in the transmission of disease, in order to effectively control the spread of disease.


Prevent mosquito bites.
Use insect repellents
When you are outdoors, use insect repellent containing an EPA-registered active ingredient. For information on EPA recommendations and the active ingredients in repellant, click here to check the CDC website.

Take precautions at dusk and dawn
Many mosquitoes are most active at dusk and dawn. Be sure to use insect repellent and wear long sleeves and pants at these times or consider staying indoors during these hours.

Keep mosquitoes out of your home
Make sure you have good screens on your windows and doors to keep mosquitoes out.

Get rid of mosquito breeding sites
Empty standing water from flower pots, buckets and barrels. Change the water in pet dishes and replace the water in bird baths weekly. Drill holes in tire swings so water drains out. Keep children's wading pools empty and on their sides when they aren't being used.
