PRECAUTIONS: The Environmental Protection Agency recommends the following steps to help reduce possible exposure to insecticides during spraying:  

• Whenever possible, remain indoors with windows closed.  
• Consider turning off air conditioning when spraying is taking place.  
• If outdoors, avoid eye contact with the spray. If any pesticide spray gets in 

eyes, immediately rinse with water or eye drops.  

• A child’s health should not be affected by the low levels of pesticides used in mosquito control.  However, bringlaundry and toys indoors before spraying begins and wash with soap and water if exposed to pesticides during spraying.  
• Bring pets indoors and cover ornamental fishponds to avoid direct exposure.  
• Cover swimming pool surfaces when feasible. Special precautions or waiting periods are not usually necessary for outdoor swimming pools given the small concentrations of pesticides used.  
• Wash exposed skin surfaces with soap and water if there is any contact with pesticide.  
• Wash exposed fruits and vegetables, such as homegrown or purchased from an outside  vendor, with water before storing, cooking, or eating them.
