Using a special formula and process (both of which are patented), Hot Pepper Wax natural insect repellent blends capsaicin with a highly refined paraffin wax and other "food-grade" ingredients. The result is a spray that coats plants with a harmless, micro-thin barrier to deter pests. Some insects are done in by capsaicin, others by the wax. Hot Pepper Wax also works as an "anti-transpirant," reducing water loss and resulting stress...a true benefit for new transplants! Hot Pepper Wax natural insect repellent is perfectly safe for garden produce, too - warm water rinses it completely away! It"s available in a ready-to-use (RTU), 22-oz. spray bottle; or in concentrate form for larger applications. Hot Pepper Wax natural insect repellent is patented in the U.S. and Canada. HPW is EPA-registered, as is its production location in Greenville, Pennsylvania.
