Solar Animal Repellent with Ultrasound & Motion Sensor | Kalsten

Every morning there is new bird droppings on the terrace – and you don't know how to stop it.

Birds seek resting places on balconies, terraces, and in the garden – leaving droppings, damage to plants, and a lot of cleaning work. This solar-powered bird repellent system automatically detects approaching birds with a motion sensor and combines ultrasound (15–25 kHz) with realistic predator sounds to keep them reliably away. No chemicals, no electricity from the socket – the integrated solar panel charges the device independently.

Benefits

• No more scrubbing bird droppings: The automatic detection in a 100-degree field of view up to 15 feet away deters birds before they land – eliminating cleaning efforts on the terrace and balcony.
• No annoying wiring or battery changes: The solar panel (6V, 50mA) charges the device daily, so you don't have to worry about power sources or regular maintenance.
• No worries about weather or durability: The sturdy plastic housing is designed for permanent outdoor use – you can leave the device outside all year round without bringing it in.

Application

1. Set up: Mount the device with the included accessories at a high point – post, fence, or wall – with a clear view of the area to be protected.
2. Align: Aim the sensor at the area that birds prefer to approach, e.g., seating area, vegetable patch, or fruit tree.
3. Let it charge: Ensure that the solar panel receives direct sunlight – after a short charging period, the device is ready for use and operates fully automatically.

Pro tip: Position the device so that the solar panel faces south and the sensor covers the main approach direction of the birds – this way, the deterrent rate is highest, especially in the early morning hours.
