A Henrico County health official says a dead crow found in Richmond was infected with the West Nile virus. The virus can cause death to mammals, including humans.
It's transferred through mosquitoes and the town of Bridgewater is fighting back.
It uses the mosquito magnet, which attracts, then traps mosquitoes. Doughnuts of B.T.I. are also used. It's a bacteria found in the ground that keeps mosquitoes from developing past their larva stage.
The town also gets rid of stagnate water.
'It's very hard to measure the decrease in the mosquito population," said Town Manager Bob Holton. "At the end of the summer we hope to send out a survey to 100 or so residents to get their impression, has it decreased, stayed the same or has it increased."
Holton says he believes the products have helped reduce the population in the downtown area of Bridgewater.
