Warren, PA - As warmer temperatures and humidity rise in the region, residents are noticing an increase in mosquitoes and black flies.
 
State officials from the Pennsylvania Department of Conservation and Natural Resources (DCNR) and the Department of Environmental Protection (DEP) say efforts are underway to manage the growing insect population—and offer advice on how the public can help.
 
“Cover your skin when possible and use bug spray,” said Cecile Stelter, DCNR Forest District Manager. "There are a lot of sprays and things of that nature that people can use. There are even insect bands you can wear on your wrists and wipes for clothing. All of these can help protect you against bites, in addition to mosquito netting, especially if you are out camping."
 
In addition to statewide spraying efforts, the DEP is encouraging residents to check their properties for standing water. Even small amounts, such as in flower pots, birdbaths, or buckets, can become breeding grounds for mosquitoes.
 
“PA residents are encouraged to help eliminate mosquito habitats by simply getting rid of standing or stagnant water on your property," said Brooke Coder, Water Program Specialist, PA Department of Environmental Protection. "That is where they lay their eggs. We’re also actively treating high-activity areas across the region to help control both mosquito and black fly populations.”
 
Black flies, in particular, tend to become more aggressive during evening hours and when humidity is high—especially just before a thunderstorm, according to the DEP.
 
“Plan outdoor activities during the midday hours and stick to bright, open spaces where black flies are less likely to gather,” the spokesperson added. “Avoiding scented lotions and fragrances can also help reduce your chances of being bitten.”
 
While the insects may be a nuisance, DEP officials say there is currently no evidence of mosquito activity in Warren County that poses a human health risk, such as West Nile virus. However, the department continues to monitor the area closely in case conditions change.
 
State agencies say they will continue monitoring and treating high-risk zones throughout the summer. In the meantime, residents can take small steps to reduce the nuisance—and risk—that biting bugs bring.
