This is year has been the worst for me getting bit by those little black bugs.....some call them No-See-Ums.
If I step outside the door, I get attacked! We actually had a swarm of them by our back door. My son used bug spray and thousands fell.
Some, however, crawled through the cracks and are actually inside my house. Luckily they have been just staying on the window, so I have been able to kill these guys too.
