Question 1

How long does it take to see results, and will the moles come back?**

Accepted Answer

Results vary significantly based on soil density and the size of your garden. While some of our customers on TikTok mention seeing reduced activity within 3–5 days, most users report noticeable changes within 2 to 3 weeks. It’s important to note that this is a *deterrent*, not an instant exterminator. The ultrasound and vibrations alter the environment to make it uncomfortable for them. However, if the device battery dies or is removed, burrowing activity may resume. For best results, keep the ground stake securely inserted and ensure the solar panel gets 6–8 hours of direct sunlight daily.

Question 2

My garden is mostly shady. Will the solar charging still work effectively?**

Accepted Answer

This is a common concern we see in online reviews. The device relies heavily on direct sunlight to build a charge for the night cycle. In shaded areas or during prolonged overcast weather, the battery may not fully charge, reducing vibration intensity and allowing pests to become braver. If your garden is primarily south-facing with high shade, we recommend positioning the spike in the sunniest spot you can find, even if that's at the edge of the affected area—it works better than placing it deep in a shadowed flower bed. These units are best used alongside mechanical traps in heavier soil conditions.

Question 3

Is the ultrasound safe for my cat, dog, or hedgehogs?**

Accepted Answer

Yes, it is entirely safe. The frequency is designed specifically to deter burrowing rodents like moles and voles with highly sensitive hearing—it’s inaudible to humans and non-rodent pets. We have not received any verified reports of distress in cats or dogs. However, for small domesticated rodents like rabbits or guinea pigs housed outdoors, we’d recommend keeping a distance of at least a few meters between the device and their housing, as they do have hearing ranges closer to that of moles.

Question 4

How does this compare to poison or traps, and is it truly "tierfreundlich" (animal-friendly)?**

Accepted Answer

Absolutely. Unlike poison baits or snap traps, this device performs a humane "eviction." It uses a dual-action system of ultrasonic sound waves and low-frequency vibrations to mimic a predator digging, encouraging moles to move to quieter territory. Many buyers specifically mention shifting to this method because they disliked the guilt of killing. One Reddit user noted that this solved their problem without the "nasty clean-up" associated with traps. It’s a lower-stress option for you and the animals, though it does require more patience than a lethal trap.

Question 5

The ground is hard when I try to install it. How durable is the stake?**

Accepted Answer

If you are dealing with clay, heavy loam, or rocky soil, we highly recommend pre-drilling a pilot hole with a screwdriver or an iron bar before inserting the spike. While the housing is weather-resistant (IP65) and made to withstand rain, the plastic spine is not designed to hammer through hard, dry earth—forcing it can snap the base. We’ve seen reviews where this is the primary cause of breakage. For existing turf, simply soak the area with water an hour before installation to soften the ground, allowing for a snug, secure fit without stressing the plastic.
