MGK-264 is a synergist. Synergists do not harm insects by themselves but they increase the effectiveness of some other insecticides. MGK-264 is low in toxicity to humans but is often mixed with other ingredients that may be more toxic. It is found in many products used inside and outside the home. It is also used in products for pets to control fleas and ticks. It is practically nontoxic to birds and mammals but toxicity to bees is not known.
