BECKLEY, W.Va. – Black flies could be abundant in southern West Virginia this year due to a lack of funding for a state spraying program.
The state generally sprays a bacterium called Bti along the Bluestone, Greenbrier and New rivers from mid-March to October control the black fly population. The bacterium kills black fly larvae.
Black fly coordinator Betsy Reeder tells The Register-Herald that the program used up a lot of its funding in 2013 because of a rainy summer.
Crews have sprayed the rivers once this season. Reeder says there’s enough money to do one more spraying.
Adult black flies feed on nectar but females also need blood to complete their egg-laying cycle. They target humans, mammals or birds.
