I see you mentioned the warning you read on the back of the package, about not using in a room that is regulary occupied.I have had no problems with them most people dont live in thier grow rooms. Also after bugs are gone. I take the strip and place a sandwhich bag over it. Maybe put one slice on the front and back of bag. Kinda lowers the strength in the room,to keep it safe for the times there is human contact with them in the growroom.But also is strong enough to keep out pest. Like i mentioned before i have been using for 5 years and no problems.
