Then, the wind started blowing and when it died down, so had the infestation. Gone, that fast. I went out early this morning, and there were hardly any of these flies anywhere, but as the day went on, a few more were showing up. I couldn't tell if they were hiding in the ant holes nearby or what. Whatever they are and wherever they are, they are not welcome and I'm not going to take any chances. After all, I raised these plants since they were just seeds. I'm totally invested.
After watching the short video, I decided that I needed to reapply the diotomaceous earth around my plants and in a much thicker fashion. I did just that. I hope I didn't go too crazy with it, but I'm told that would be impossible. We'll see. I sure hope it works!
P.S. I'm pretty sure I'm allergic to whatever those flies are because my face and nose got totally itchy around them.
