Probably the April freezeSame, I had one mosquito on me this morning but that's it, usually they are swarming. I've still got some fire ants around but there does seem to be fewer mounds this year, now that I think of it within the last couple of weeks I've noticed fewer deer flies as well. Weird considering the high humidity
edit: now, the gnats, that's an entirely different story..... whatever has run off the other stuff don't mess with gnats, they are horrendous.
