I used 2 pyrethrum bombs about 6,000 square feet of coverage and hung 2 pest strips

That'll do it. But you didn't need the bombs. Better safe than sorry I guess. You should not see any more (unless someone brings them in) until the next light change from veg to bloom. If you are lucky you won't see any more ever. Just repeat the process if need be at that time, and that should be it forever. Yeaaaah. Just be real carefull about bringing them in again. I wasn't kidding about burning your clothes if you go to an infested grow room. Also if you can, scrub down completely with a neem oil solution or something. Use pyrethrum if you don't mind going steril.

congrats.
