Pesticide Safety

  • When used correctly, pesticides pose no significant health risks to people or their pets.
  • No reported diseases in people or pets have been linked with the use of pesticides in West Nile virus control efforts since 1999.
  • People who are sensitive to spray ingredients may get a rash or have short-term eye or throat irritation.
  • If you have a stronger reaction to pesticides, call the NYC Poison Control Center at 212-POISONS (212-764-7667).
  • To minimize pesticide exposure:
    • When possible, stay indoors during spraying. If you have asthma or other respiratory conditions, stay inside.
    • Set the air conditioner vent to the closed position or choose the recirculate function.
    • Outdoor equipment and toys that are exposed to the pesticides we use are not a significant health risk. There could be some residue for a short period of time. Although it is not necessary, you can wash the toys and equipment with soap and water.
    • Wash skin and clothing that have been exposed to pesticides with soap and water. Always wash your produce thoroughly with water before cooking or eating.
