Questions? We've got you.
Slate Signal is a portable outdoor device that emits a changing ultrasonic signal. It is designed as a chemical-free companion for patios, campsites, gardens, and other outdoor routines.
The device produces a shifting pattern of high-frequency sound rather than dispersing a topical or airborne repellent. Ultrasonic pest devices are not EPA-registered insect repellents, and real-world results can vary.
It is designed to operate above the range most adults hear. Individual hearing ranges differ, so stop using it if you notice an uncomfortable sound.
No lotion, spray, smoke, or fragrance is released by the device, and nothing is applied to your skin.
Use it as directed near your patio chair, garden setup, campsite, day bag, or other outdoor activity. Keep the emitter unobstructed and follow the included product instructions.
No. Do not rely on an ultrasonic device alone where mosquito- or tick-borne disease is a concern. CDC recommends EPA-registered insect repellent, protective clothing, avoiding tick habitat, and checking for ticks after outdoor time.
Some animals hear higher frequencies than people. Keep the device away from pet resting areas and ask your veterinarian before using it around pets that may be sensitive to sound.
Processing takes 1-3 days. Estimated US delivery is 4-7 days after dispatch, and tracking is provided when your order is on its way.
