What’s funny is they’re not as bad where I live (central Jersey) this year. I have noticed the ones I do see are much more nimble and can fly further. Philly had the same situation where the population of the flies exploded but then receded after a couple of years. From the article I read about it scientists aren’t sure of why.
Yeah, I had to tape off the trees in my yard to keep these jerks from killing them. I was shocked at how often I had to replace the tape, it’d get to the point where they were able to crawl over the corpses already stuck on the tape. Thankfully that was last summer, this year I saw maybe 10% of the volume of the previous summer. What’s gross is you can see them spray while they devour the tree, it’s disgusting.
