It’s Mosquito Trapping Season!

It’s mosquito-trapping season!

Adult mosquitoes are collected every two weeks during the summer months from routine sites around the state. DHHS staff use mosquito traps (pictured) to collect and identify female (blood feeding) mosquitoes to species and count them. They are then pooled in the genus Culex in vials of up to 50 mosquitoes of the same species and sent off to the lab for testing for West Nile Virus. 

PHS district mosquito-trapping results can be found on our Environmental page under “Animal/Insect Bites” and provide a snapshot of mosquito trapping data throughout the summer.
