As a reminder, mosquito spray creates a very fine mist, the droplets of which must actually come in contact with an adult mosquito to be effective. The chemical is very specific to mosquitoes and does not affect other flying insects.
The spray is not harmful to people or pets. That said, some individuals are very sensitive to any material suspended in the air. We keep a registry of those individuals and we notify them in advance of spraying so that they can remain indoors the night of the aerial spray.
