The amounts of mosquito control pesticides that are sprayed out of the trucks are not harmful to people or pets. However, as with any pesticides, it is a good idea to keep exposure to a minimum. For this reason, children should not be allowed to follow the mosquito trucks as people often did in the 1940s and 1950s. Pets usually are repelled by the high pitch of the machine. Therefore, even if it seems that they are not spraying, the trucks should not be followed. Unless someone is very sensitive or allergic to pesticides, washing the skin with water is all that is needed. At the low insecticide dosage used, no symptoms should be experienced. People who are sensitive should call the office and notify us prior to any spraying.
