WLBZ interviews Dill about black fly population

Griffin Dill, an integrated pest management professional with the University of Maine Cooperative Extension, spoke with WLBZ (Channel 2) for a report about Maine residents claiming to see more black flies this year. Dill said the amount of black flies you see depends on where you live; with more being found close to water sources. According to Dill, lots of black flies means the state’s rivers and streams are clean because the flies will only lay eggs in clean water. “Because of that we see this large number of black flies every year,” he said. “We tend to have a fairly steady population of black flies.” Dill added the days of black flies only being around from Mother’s Day to Father’s Day is a thing of the past, WVII reported. “We are lucky enough to encounter black flies throughout the entire summer, not just for that early spring season,” he said.
