Wondercide is proven to work without the conventional ingredients. Our lineup of plant-powered sprays, spot ons, collars, and shampoos harness the power of nature to do the job. Lab-tested to protect your pet from fleas, ticks, and mosquitoes. Loved by people, pets, and pollinators. It’s all good. WATCH NOW 1 Shake well before each use. 2 Test a small area at the base of the neck 1 hour before full body application to check for sensitivity. This is a smart step when introducing any new product. Pets, like people, can have sensitivities to plant-powered ingredients too. 3 Rub your pet’s coat in the opposite direction of growth, spray, and rub in. Spray body, belly, legs, and tail. Do not soak your pet or oversaturate. A light but thorough misting ensures best results. 4 Spray into your hands and rub onto your pet's ears and face. Avoid spraying in mouth, nose, and eyes. 5 For continuous protection, reapply daily, every 24 hours. Apply before going to an area not protected by Wondercide such as a dog park or on a hike. 6 Add to your regular cleaning schedule to freshen the home and treat areas frequented by pets. Test specialty fabrics like silks and suedes before full use. This is a water-based product with oil.
