Residents can take following precautions to reduce exposure:

Plan your activities to limit time spent outside during times of possible insecticide treatments.

Move your pets, their food, and water dishes inside during ULV application. Also bring clothing and children’s toys inside.

Stay away from application equipment, whether in use or not.

Whenever possible, remain indoors with windows closed and with window air conditioners on non-vent (closed to the outside air) and window fans turned off during spraying.

Avoid direct contact with surfaces that are still wet from pesticide spraying. Do not allow children to play in areas that have been sprayed until they have completely dried (approximately one hour).

If you must remain outdoors, avoid eye and skin contact with the spray. If you get spray in your eyes or on your skin, immediately flush and rinse with water.
