Here in SE Massachusetts, we get our share of airborne pests as well. It starts in early april with herring flies (probobly a variant of the black fly. We call them herring flies I suppose because they arrive with the spawning herring). Then the mosquitos, some of which could carry a small animal away. We also get tons of deer flies and horse flies. But the real fun comes from the the horse flies on steroids. I'm not kidding when I say they get to be almost 2 inches long. When they bite, they take a BIG chunk of flesh away. I once whacked one with a shoe, and it still managed to fly away. It seems that we are never lacking for annoying insects. And the bastards have the whole day covered....Mosquitos early morning and late evening, horse and deer flies during the hot part of the day.
The wonderful state of Taxachusetts will come and spray for mosquitos, but you have to call and ask each week. They come weekly and spray plus at certain times they will put pellets in standing water. It is beautiful for a day or two after they spray. God, I hate bugs!!
