Help! We are experiencing a plague of black moths all over our yard and in our garage during the daytime. These are medium size moths black or dark brownish with a darkish design on the wing. We live in a rural area next to a field. We were using a bug zapper with an attractant, but turned it off because of this. Never had this before. This is the first year that we didn't notice bag worms on trees because we have plenty of wild plum and cherry (if that's relevant). These moths are not easy to spray either. They still land on areas that I have sprayed with a long lasting spray. And they hide under crevices in addition to flying all over the place in the daytime (nighttime is unbelievable).

They are probably green cloverworm moths and they are harmless and treatment is unnecessary. It is true that they are a nuisance. They will disappear as soon as winter arrives.
