Im not positive at all. I put it in the infirmary to see what others say. Hoping there is just a pistol waiting to pop out of there. Im sure there gnats. best way to stop them is nematodes and yellow sticky traps and letting the top soil dry out a bit. mine are gone NowI know.....are you positive? Now I got gnats or something flying around....shit....come here you little bastards...lol smack
