Other Control Measures
Spraying is not the only measure taken in a comprehensive mosquito control program. During the day, the ditches of the city are sprayed with a chemical and oil mixture to kill mosquito larvae before they mature. Also chemical briquettes are placed in some ditches to provide long-term control of larvae. Each citizen can help in the control of mosquitoes by taking the following measures:
- Get rid of standing water on your property where mosquitoes might breed.
- Properly dispose of tires, cans, flower pots, etc.
- Keep gutters clean and freely flowing. Standing water in gutters can breed mosquitoes.
- Keep swimming pools, spas, and fountains properly treated with chemicals.
