I have vacationed here for years at Christmas and there are not any of these lovely insects. This is my first time in the Fall and the sunrise is beautiful, the days are beautiful, but it is now 7:30 PM and I am a prisoner of my unit, due to these pests. (We like to play night time bocce and can not do this.) I am told that these insects disappear in mid-November!

Consider yourself lucky. We, too, are Christmas visitors, and there have been years when they have been plentiful. I often go home with several welts. A good cold snap knocks out the noseeum population for a few weeks, and, in many years, one hits in early/mid December, making our 2 week stay fairly bug free. But, not always. In the years they are around, they are plentiful on the beach and at the refuge near dawn and dusk,

Deet works, somewhat, but you really need a broad spectrum fly repellant.
