There’s no need for harsh chemicals to kill unwanted plants. The NatureZap is a rechargeable battery operated alternative to propane weeders. Instead of chemicals, which may effect the soil and groundwater, this non-toxic weed killer uses heat and light to safely kill weeds in pavers, sidewalks, gardens, and yards. The wand is equipped with an infrared light that creates heat for cutting off the water supply from roots and a UV light which penetrates the ground to disrupt root functions. It’s safe for people, places, and pets.
