Other than horse flies, the only flying/biting insects I have are mosquitoes, and after 3 rounds of larvicide of my seasonal wetland over the past 2 months, I have not seen even one. Left untreated, I would have an unbearable swarm by now.
Plenty of chiggers around if you venture into the 'wrong' area. The itch from their bites are the worst, and can last a month.
