A natural way to kill those pesky bugs. Our peppermint lemon spray kills on contact. It kills anything with an exoskeleton: ants, flies, spiders, beetles, or whatever critter has decided to invade your home. Our ant and roach killer powders are specifically formulated to attract ants or roaches. These powders DO NOT kill on contact. They are designed to attract ants or roaches which then eat the powder and take it back to the colony where they become unwitting assassins for their entire colony.
