Not vampires: Mosquitoes, and August brings them out in droves.
Local health departments are working to make sure mosquitoes don't deliver anything more than an irritating itch.
Once a week, Henry and Stark County Health Department Inspectors go out to collect mosquitoes, and then bring them back here to test them for the West Nile Virus.
The Environmental Health Division of Henry and Stark County check a net they've set up, and attracts the blood suckers.
The net stands in a pool of stagnant water, and traps them.
"We take the net into the office if we have mosquitoes in it. We will grind it up to test it," Sadie Dorothy David, Director of Environmental Health.
In the lab, the mosquitoes are sucked up by a vacuum, and ground up into a liquid.
"The virus is in the mosquito itself, so if we don't grind it, we won't be able to test whether there's virus in the mosquito itself or not... Within 5 to 10 minutes we get the results already, whether there is West Nile in the mosquitoes or not," said Director Dorothy David who added mid to late August is when the number of human cases of west nile reaches it's peak.
Although, Henry and Stark County haven't had any cases yet, 41 counties across Illinois have.
Alice Horri spends a lot of time outdoors, and said she's worried about catching the virus, "I try to avoid any type of mosquito related environment."
Which is exactly what health departments said you should do, especially between dusk until dawn.
"Don't keep stagnant water, if you're going out wear long sleeves, and apply insect repellents," said Director David.
