I've used them for years, no problems, no bugs ... I hang one in the same room as my grow cabinet ... no need to place it right next to your plants, just in the same room will be good enough ... I remove them two weeks before harvest, as there will be NO bugs in the room ... wash your hands after handling anything like that, but no special worries ... it's poisonous to bugs, but harmless to humans IF used according to the directions ... YES, you should READ the directions ... that alone will scare a lot of our people away ! ... you will doubtless hear dire warnings from tree-hugging environmentalists, but use some common sense ... don't taste it, don't bake it into a cake, and don't put a nipple on it, for feeding to your infants ... mmmm, probably shouldn't smoke it, either ... they work well ... as to removing the bugs and eggs from your plants, well, no really 'good' way to do it ... (just try not to think of what all you've smoked in the past, when you bought pot off the street, the bugs will probably seem tame, compared to your imagination) ... :smokin:
