I was recently pulling some weeds from my yard. These weeds are the ones that tend to spread out over the rocks like ground cover. Anyway, when I did so hundreds of tiny white gnats flew up in a cloud and ended up biting my hands, arms, face, etc. They seem to have infested all of the weeds in my back yard.
I have noticed them before but never this bad and apparently my skin is quite sensitive to them!
Any thoughts of what these are and how to control them?
