10 Best Rodent Repellers 2025 in the United States

The OWLTRA OW-5 Ultrasonic Rodent Repellers come in a set of four plug-in devices designed to repel rodents using high-frequency sound waves that are inaudible to humans and most pets. Each unit covers a medium-sized room, making it a good choice if you want to protect multiple rooms from rodent activity without using poisons or traps. The repellers are convenient to use – just plug them into standard wall outlets, and they start working immediately. A helpful feature is the built-in night light that softly glows to indicate the device is active.

Safety is a strong point here, as these repellers are non-toxic and safe around children and pets, which is ideal for households looking to avoid chemical pest control methods. However, ultrasonic sound waves can’t travel through walls or solid objects, so placement is important. To get the best results, you need to place one unit per room and avoid plugging them in near furniture or other barriers. Some users might find that it takes up to two weeks to notice a reduction in rodents, and using these devices alongside traps or baits could be necessary for larger infestations.

The OWLTRA OW-5 repellers provide a quiet, chemical-free solution suitable for homes needing mild to moderate rodent control, especially in spaces where safety and ease of use are priorities.

The Tomcat Rodent Repellent spray is a convenient option if you're looking to keep mice and rats away without using traps or poisons. It works by spraying a blend of essential oils that create a scent and taste unpleasant to rodents but is designed to be safe around kids and pets when used correctly. You can use it both indoors and outdoors, which adds versatility, especially around doors, windows, and other common entry points.

One of its strong points is the continuous spray coverage, which makes application simple and helps protect about 275 square feet per 14-ounce can. It’s also rain-resistant, so it holds up well outdoors, but you will need to reapply roughly every 30 days to maintain effectiveness. Since it’s a spray, it doesn’t require electricity or batteries, making it easy to use anywhere.

On the downside, as a spray, its protection is limited to areas where you apply it, so it’s not a full-room electronic solution that covers larger areas automatically. The scent might be mild, but some users may still notice it, and it requires regular reapplication, which might not be ideal if you want a set-and-forget solution. It’s also not designed to kill rodents but just to deter them, so it may not be effective if you already have a significant infestation. This product is best suited for people who want a natural, low-maintenance way to discourage rodents from entering specific spots around their home or garden. It’s not ideal for heavy infestations or those wanting a device with wide continuous coverage or electronic features.

The Loraffe Under Hood Rodent Repeller is an ultrasonic device designed primarily for vehicle protection. It uses a combination of fluctuating ultrasound waves and dual LED strobe lights to deter rodents, which is a strong feature in terms of multi-sensory deterrence.

The device operates on 3 AA batteries, lasting up to 45 days, which means it requires regular battery replacements but avoids the need for wiring or an electrical outlet, making installation simple with the provided zip ties. It's designed for vehicles but is versatile enough to be used in various locations like garages, attics, and barns, expanding its utility.

One of its energy-saving features is the auto standby mode while driving, which helps to conserve battery life. This product is particularly suitable for those looking for a portable and easy-to-install solution for rodent problems in their vehicles or small areas.
