Piperonyl butoxide (PBO) is a man-made pesticide ingredient called a synergist. By itself, PBO does not harm insects. Instead, it works with insect killers to increase their effectiveness. PBO is low in toxicity to humans but is often combined with other pesticides like pyrethrins or pyrethroids. PBO is practically non-toxic to birds, mammals, and bees. However, it is moderately toxic to fish.
