i had luck when we got bugs wtih a bug bomb from a local hydro store. your supposed to set if off when the lights go out. that helped us out so we didn't have to figure out the names but...lol i guess that was the easy way out too
I'm not saying it's safe and I'm not saying to do it but...they make bug bombs with pyrethrum which is made from chrysanthiums. That is the only bug bomb I would use and I would only do it in a empty room or one with plants in the first month of veg. Any further in and it's a no-no.
