Any insecticide will kill the Monarch butterfly. The only way to kill milkweed pests like the milkweed bug and the long horned beetle without harming the butterfly is to just knock them off into a jar of undiluted dish soap. It kills them almost instantly and it is easy. It also works for the earwigs and Japanese beetles. You will never get rid of all unwanted insects but it does cut down on their numbers and the damage they do.
