The products we use are targeted to control flying adult mosquitoes. Adult mosquitoes are most active at night whereas beneficial insects - such as bees - are active during the day. That is why when applying adulticides, we treat at night. The products are applied at very low dosages that kill a flying mosquito on contact, then degrades. When the product is exposed to sunlight, the ingredients become inactive.
The US Environmental Protection Agency (EPA) has evaluated pesticides for their safety and has determined that they do not pose an unreasonable risk to birds or mammals, if used according to the product label directions.
Residents may choose to stay indoors during and for 30 minutes following the application as a best practice to reduce exposure. After going back outside, residents should not see any visual signs of the treatment on their property.
