Surveillance
We use four primary trapping methods to collect adult mosquitoes.  Gravid traps use a stink water lure to draw in female mosquitoes that have blood fed and have eggs.  CDC traps use a CO2 lure to attract female mosquitoes looking for a blood meal.  Light traps attract mosquitoes using a light and a fan to suck them in the trap.  Resting boxes for mosquitoes resting in the shade during daytime hours. 
Ground Larviciding
Our inspectors make a circuit of the entire county every week to look for breeding sites and treat areas with a biological larvicide called B.T.I. (Bacillus thuringiensis israelensis) ​a naturally occurring soil bacterium. 

Adulticiding is used in addition to larviciding, but used only in the event of extreme high numbers of adult mosquitoes or in the presence of virus activity.  
Aerial Larviciding
Our inspectors perform continuous checks of all salt marshes by helicopter and on foot at least twice a week during the breeding season.  There are 28,000 acres of salt marsh in the county.  In 2017; 13,500 acres of the salt marsh were treated.  

Open Marsh Water Management is a technique used to allow native fish species access to areas of the marsh to eliminate mosquito larvae.
