Infestation in my greenhouse
I have a small hobby greenhouse and am new at it and in the last couple years am trying to save my million bells. I get small (round looking) green bugs that get all over the plants (dont bother my geraniums) but just the million bells. Almost look like sawdust everywhere...white stuff. Never seen anything like it. I have roses outside and have seen the small aphids but these are different. I want to save my plants. Any advice?
