I wouldn't think a whole lot of insects could survive the trip through the intake fan.
I draw intake from a room that has had an ac running since may 1st... and I live up north! Works pretty well.

Insects... put a couple layers of stocking over the intake if you are really worried, but if you are drawing from indoors it isn't so much a problem... mites can certainly get through a fan, the indestructible little SHITS
