CALYVEO Ultrasonic Tick Repelling Device

Calyveo is an 11-gram ultrasonic device that emits a wide-band pulse (19.5–135 kHz) designed to disturb ticks and biting insects before they ever reach your skin.

No DEET soaking into your kid's arms. No permethrin on your gear. No reapplying every two hours. Just a long-press of a button and you're covered.

Clip it to a backpack, belt loop, hat brim, or shoelace. At the weight of three quarters, you'll forget it's there — until you get home and realize you didn't pull a single tick off anyone.

Built for how you actually live outside:

• Runs 2–4 days on a single charge — a full camping weekend without a recharge
• Charges in 1–2 hours with the same USB-C cable as your phone
• Splash and rain resistant, so a wet trail day doesn't end your protection
• Silent to you, your kids, and your pets — the frequency sits above human hearing

Whether it's deer stands in November, soccer sidelines in June, or the backyard every day in between — PULSE™ is a chemical-free layer of protection you set once and stop worrying about.

Use it alongside your normal tick checks. Backed by our 99-day money-back guarantee: if you're not happy, you get a full refund. Simple.

How to Use Calyveo

1. Charge it. Plug in the USB-C cable for 1–2 hours until the indicator light shows full.
2. Clip it on. Backpack, belt loop, hat, shoelace — anywhere on your outer layer works.
3. Long-press to power on. That's it. You're protected for the next 2–4 days.

No sprays. No reapplying. No steps to remember. Charge it, clip it, go outside.

Yes — safety is the whole reason Calyveo exists. There are no chemicals, no sprays, and nothing that absorbs into skin, so there's no DEET or permethrin to worry about on your kids or around your pets.

The device works using ultrasonic sound waves that sit above the range of human hearing — your family won't hear a thing. It's calibrated to run at a low intensity, so it won't bother dogs or cats either.

At 11 grams with no small detachable parts in use, it clips securely to a backpack, shirt, or collar. Charge it, clip it on, and let them play.

Calyveo emits a wide-band ultrasonic pulse (19.5–135 kHz) designed to disturb ticks and biting insects before they latch on — the frequency interferes with the sensory organs they use to find a host. It's silent to you, your kids, and your pets, and there are zero chemicals involved.

We recommend using it as an added layer of protection alongside your normal routine, like tick checks after time outdoors. And if you don't notice a difference, you're covered by our money-back guarantee — no questions asked.

You can — if you don't mind reapplying DEET every two hours, spraying chemicals on your skin, and the smell that comes with it. Calyveo works differently: charge it once, clip it on, and you're covered for 2–4 days with zero chemicals, zero residue, and zero reapplying. It costs about the same as a summer's worth of spray — except you never buy it again.
