Mosquito Control

The Public Works Department handles mosquito control operations for the Town. 

How Often Does Town Spraying Occur?

mosquitoThe Town of Firestone sprays adulticides and larvicides as needed. Each season is different, so the frequency varies. Mosquito traps are set in strategic locations throughout Town to determine mosquito type and population. If there is an increase in mosquito population, the Board of Trustees considers changes to the mosquito control schedule.

Which Days are Designated for Mosquito Control Spraying?

The Town generally sprays between 8:30 p.m. and 10 p.m. on Mondays and Thursdays (weather permitting) at the height of mosquito activity, in order to eliminate a larger population of mosquitos.
