So I placed about a dozen LBs in my flowering room and they instantly started patroling the plants for food. After a while though, you noticed that some just want to sunbathe or burrow themselves a bit and sleep in the soil. It was nice knowing while I was at work the mercenaries were counteracting the pests.
I also had a huge escape, about 70 got out and were all over the room, it was fine though, my gf and I had a lot of fun catching them all, and it only took about an hour, lol....
I'm going to build a better enclosure tonight, and I plan on introducing more tonight before the lights come on.
Oh, and spraying with soda pop water/sugar water is almost essential. It helps a ton if they get out, and prevents them from flying into my air-cooled hood (which I'm going to cover with a screen, my fixture is on a light mover so the holes on the sides are exposed).
