MHNKACA Solar Animal Repeller 2-Pack — Ultrasonic Motion-Activated, Waterproof

The MHNKACA 2-Pack Solar Animal Repeller is a solar-powered ultrasonic and flashing-light device that detects motion and discourages deer, rabbits, squirrels, raccoons, and other small to medium wildlife from gardens, patios, and yards.

If you want a low-maintenance way to protect plants, landscaping, bird feeders, and outdoor living spaces without chemicals or traps, this pair of repellers offers solar charging, a passive motion sensor, and a waterproof housing for year-round outdoor use. Each unit combines an ultrasonic speaker with a red LED flash and a 110-degree motion detection arc that reaches up to roughly 33 feet, creating an unpleasant environment that encourages animals to move away.

How does the motion detection work and what range can I expect?

Each repeller uses a PIR motion sensor that scans a wide 110-degree arc and triggers when movement is detected within about 33 feet. When triggered, the unit emits a short ultrasonic burst and flashes a red LED for 15 seconds, then returns to standby mode to conserve power.

• Detection angle: 110 degrees
• Detection distance: up to ~33 feet
• Activation pattern: 2.5 seconds of sound at the start, total active period 15 seconds
• Standby after activation to preserve battery life

How do I install and position the repellers for best results?

Installation is straightforward: open the switch, place a stake in prepared ground or use the built-in hanging holes to mount on fences, trees, or walls. For optimal performance, keep the device head about 9–10 inches above ground to maximize sensor coverage and sound projection.

• Ground stake for lawn or garden placement
• Two hanging holes for fence, wall, or tree mounting
• Keep head 9–10 inches above ground for best detection
• Ensure direct sunlight for solar charging — charge 2 hours initially

Is this repeller weatherproof and which animals will it deter?

The units are made from durable ABS and rated IP44 for water resistance, suitable for typical outdoor exposure like rain and light moisture. The ultrasonic pulses and flashing light are intended to deter a variety of small-to-medium animals; effectiveness varies by species, habituation, and site layout.

• Construction: impact-resistant ABS plastic
• Water rating: IP44 — protects against splashing water
• Common pests targeted: deer, rabbits, squirrels, raccoons, skunks, stray cats and dogs, gophers, voles, moles, chipmunks
• Note: avoid submerging or exposing to extreme weather beyond IP44 limits

What maintenance and power considerations should I know about?

These repellers run on built-in rechargeable batteries charged by the integrated solar panel, keeping upkeep minimal. To ensure reliable operation, place units in locations that receive regular sunlight and power them off before an initial two-hour direct-sun charge for a full starting battery.

• Solar-powered rechargeable battery — no wiring required
• Place in direct sunlight for best charging; initial 2-hour charge recommended
• Turn off when not in use or during prolonged low-sunlight periods to conserve battery
• Avoid hard impacts when installing; prepare ground to reduce stake damage

Who is this for? The MHNKACA 2-Pack Solar Animal Repeller fits homeowners, gardeners, and small-farm owners who want a non-lethal, maintenance-light method to discourage wildlife from flower beds, vegetable plots, patios, and compost or trash areas. It’s best for outdoor spaces receiving regular sunlight, where a wide-angle motion sensor, short ultrasonic bursts, and flashing LEDs can complement physical barriers and good wildlife-proofing practices.
