I don’t know tweva. Last winter really did a number on the mosquitos around here. I’m often out real early in the early morning working in the yard and unlike every other year, I rarely was bothered with mosquitos this year. Same thing early evening when the mosquitos are usually out in abundance…almost none this year. I think what happened was when they were hatching out last spring the cold kept killing them off. That extra month of winter did pay some dividends. I’ll bet it whacked the tick population back pretty good too given how deep the frost went. Then again I’m still in shorts until it drops below 50 degrees, unless its sunny & not windy and then I’m good in shorts down to about 45. Genetically adapted to the cold I suppose.
