Briefly, here's what we do during Mosquito Control Season in the Mosquito Control Districts:
In the Spring, usually in April, mosquito control staff places larvicide briquettes into roadside ditches.
As they are out in the mosquito control districts, staff also distributes mosquito control release forms to residents whose homes are more than 150 feet from a public road.
Next mosquito surveillance begins. This is a period of watchful waiting to determine when and where the mosquito population warrants application of adulticide.
Mosquito control trucks deliver an adulticide fogging in mosquito control districts only when surveillance indicates that an application of adulticide is needed, with the need usually ending in the month of October.
