Tirgo Solar Ultrasonic Outdoor Repeller 4-Pack — Motion Sensor & Strobe LED for Yard

The Tirgo 4-pack solar ultrasonic outdoor repellers use motion detection, ultrasonic pulses and flashing LEDs to humanely discourage deer, squirrels, cats, raccoons and other animals from gardens and yards.

Keep plants, lawns and outdoor spaces free of digging, trampling and unwanted visitors without chemicals or traps. Each compact unit runs on built-in solar panels, activates automatically when the PIR sensor detects movement and combines high-frequency sound with a strobe flash to startle animals and encourage them to leave the area. Weather-resistant housing and a detachable stake make the devices simple to install and move where they’re needed most.

How does the motion detection work and when will the device trigger?

The integrated PIR sensor scans a wide field and responds to warm-body movement within a set distance. When activity is detected, the repellent emits ultrasonic tones and a bright LED strobe for a short cycle, then resets to standby to conserve power.

• Detection angle: approximately 110 degrees for broad coverage.
• Trigger distance: roughly 25–33 feet depending on size and speed of the animal.
• Automatic operation: wakes with motion, cycles, then returns to low-power standby.
• Solar charging helps maintain operation without frequent battery swaps.

What kinds of animals can this Tirgo repeller deter?

Designed as a general outdoor deterrent, the combination of ultrasonic sound and strobe light deters many common garden intruders. Effectiveness varies by species, local behavior and placement, but the device targets mammals and birds that respond to sudden noise and bright flashes.

• Commonly deterred: squirrels, rabbits, raccoons, deer, chipmunks and feral cats.
• Also useful against: skunks, foxes, stray dogs and some pest birds.
• Not species-specific: best paired with good placement and multiple units for larger areas.
• Humane approach: non-lethal, purely sensory deterrent—no poisons or traps required.

How do I install and position the units for best coverage?

Installation is tool-free: assemble the stake or use the ground mount, then angle the head toward expected entry paths. Solar panels should face direct sunlight and the sensor should have a clear view of the area you want to protect.

• Mounting: stake into lawn, soil or use flat-mount for patios and decks.
• Orientation: point sensor toward animal approach routes (paths, fences, garden beds).
• Spacing: place multiple units around perimeter or every 20–30 feet for larger lawns.
• Sun exposure: ensure panels receive several hours of sun daily for reliable charging.

Is the device durable enough for outdoor weather and camping use?

The housing is made of tough ABS plastic and rated to repel water and resist the elements so it can stay outdoors through changing weather. The detachable design also makes it easy to pack for temporary use at campsites or patios.

• Material: high-strength ABS resists cracking and UV exposure.
• Water resistance: IPX4 splash- and light-rain protection suitable for typical outdoor use.
• Portable: lightweight and removable stake for transport to campsites or gardens.
• Low maintenance: solar charging reduces battery replacements and handling.

Who is this for? The Tirgo 4-pack solar ultrasonic repellers are aimed at homeowners, gardeners, small-acreage property owners and campers who want a chemical-free, non-lethal way to protect flower beds, vegetable plots, lawns, patios and orchards. If you need a low-maintenance deterrent that can be repositioned seasonally or used at temporary sites, these units offer flexible coverage without traps or poisons.
