No, no deer flies. Loads of wasps though. I think there may have been a few nests around. I already had an intense fear and dislike of those critters due to some childhood incidents, so that did not endear them to me at all.any deer flies? those bad boys can chomp out tiny plugs of skin, the bastards. skeeters, the bastards. proper balance of spiders in your realm is a godsend. and a trained jack russell or two for almost everything else.
