We went to Maine for a family vacation in 1982 at a cottage type place my Dad and his family went to back in the 1950s, lol. Saw Boothbay Harbor and the nearby area. The area where the cottages were was apparently just as infested with mosquitos as it had been when my Dad was there as a kid, also lol.
Mosquitos are known as the state bird in ME.
This is also why every house has a screened in porch. If not, you cannot sit outside in the evening without bathing in DEET first.
