Mosquito Spraying

June 20, 2018

The City of Quincy will provide periodic spraying for mosquitoes. Mosquito spraying will typically be performed in the late evening while most of the city population is indoors. Weather conditions will dictate the available times to spray since spraying will not be performed during rainfall or when wind speeds are 10 mph or greater.

Mosquito spraying will not eliminate mosquitoes completely. We ask that residents also take action against mosquito infestation. The most effective way to reduce mosquitoes in your neighborhood is to remove their source — standing water. Thousands of mosquitoes can hatch from a puddle of water that is stagnant for at least four days.

What should I do during the spraying?

You do not need to do anything. If you want to take extra precautions, you can refer to these suggestions:

  • Remain indoors with children and pets and cover any ornamental fish ponds, beehives or organic gardens. Stay indoors at least an hour after spraying has concluded.
  • Close windows and doors, and turn off window-unit air conditioners or set to recirculate indoor air only.
  • Do not let children play near or behind truck-mounted applicators when spraying is taking place.
  • Drive cautiously around the spray vehicle and pass it with care.
  • Avoid eye or skin contact with the spray if you are outside, and wash any exposed skin with soap and water if you come in contact with the spray.

What should I do when the spraying is completed?

You don’t need to do anything. If you want to take extra precautions, you can follow these suggestions:

  • Rinse any fruit and produce left outside during spraying before eating.
  • Because the spray droplets falling on the ground become inactive in just a few hours or with sunshine, it is not necessary to wash off outdoor furniture or playground equipment before use.

What pesticides will be used in the spraying?

How safe is it?

Pesticides that are used for mosquito control have been judged by the EPA not to pose an unreasonable risk to human health. Spraying is scheduled in the evening to limit exposure to people who may wish to avoid contact with the pesticide used to control mosquito populations. Spraying begins at 8 p.m.

People who are concerned about exposure to a pesticide, such as those with chemical sensitivity or breathing conditions such as asthma, can reduce their potential for exposure by staying indoors during the application period. Anyone who thinks they have been affected should check with their primary healthcare provider.
