I think them little f*ckers will take away all yout trichomes on their f*cking little feet. I would kill em all as soon as possible. It must be warm where ya are.I have seen only a few flies around here. And I think they call them green bottle flies. I have seen a little item they have sold here in the summer. It is a fly trap that is like a plastic bag,that has an entrance in the top of it. You put in this powder that comes with it and mix with water. It smella like a dead animal when it activates. It would be a great camo for any smells you might have drifting in the air too
Good luck amigo
