Question 1

Is this mouse repellent safe for my car's computer and electrical system?**

Accepted Answer

Yes. The device is designed to be electronics-safe. It emits ultrasonic and electromagnetic waves intended to disturb rodents, not interfere with modern vehicle electronics. Many users on automotive forums have reported using similar devices without issue. For absolute peace of mind, you can place it in a central location in the engine bay away from direct contact with wiring harnesses.

Question 2

How do I power it in my car, and how long will the battery last?**

Accepted Answer

You have two flexible options. For continuous protection in a garage or attic, use the included plug-in adapter. For your car, use the 4 AA batteries (not included). In battery mode with automatic frequency conversion, you can expect up to 4-6 weeks of operation. A common tip from TikTok users is to change the batteries seasonally as a routine, like when you prepare your car for winter storage.

Question 3

I've heard mixed reviews on effectiveness. How can I tell if it's working for me?**

Accepted Answer

This is a common and valid concern. Since it's a repellent and not a trap, you won't see "proof" like caught mice. Success is measured by the *absence* of new rodent activity—no new nesting materials, droppings, or chewed wires. It works best as a preventive deterrent. For existing infestations, we recommend combining it with trapping to remove current pests, then using the repellent to keep new ones away. Reddit users often suggest giving it 1-2 weeks to encourage existing rodents to relocate.

Question 4

What's the real coverage area? Will one device protect my entire garage?**

Accepted Answer

The coverage is effective for a concentrated area like a single car engine bay, a small attic space, or a pantry. For a standard two-car garage, the waves may not reach every far corner effectively. Based on social listening, users with the best results use it for targeted protection. If you have a large garage or barn, you will likely need multiple units placed strategically for full coverage, as the signal can be blocked by dense materials.

Question 5
