Top 10 Repellers
for March 2023

The Bell & Howell Ultrasonic Pest Repeller Kit performed well at keeping out mice and rats, and at repelling spiders and roaches, but it could struggle with ants and roaches. It uses a low-frequency ultrasonic sound wave that rodents and insects find unpleasant, so these pests run away. The ultrasonic waves don't travel between walls, so you'll need to use one per room. The included user manual is a bit confusing, but the pest repellers are easy to set up and work as advertised. The repellents emit constant ultrasonic waves, so any rodent or insect that hears the sound will run away, but it won't hurt your pets or hearing, and it won't affect nearby electronics. The repellers require no electricity or upkeep, and (unlike chemical repellents), they don't emit any chemicals and are odor free. The pests are repelled, so they won't come near your home, and you won't find any evidence of the pests when you get home. The repellers are silent, so they won't disturb you, and they don't emit any odor, so you can put them anywhere. However, the repellers will only work on mice, rats, spiders, and roaches, so they won't keep out ants. The repellers don't cover a large area, so they're not ideal for large spaces, such as warehouses or offices, and they don't protect from flying insects, such as mosquitoes. The Bell & Howell Ultrasonic Pest Repeller Kit is a great solution for keeping mice, rats, spiders, and roaches out of your home, and it does a good job at keeping out spiders and roaches, but it won't keep out ants.

Our previous top pick, the ultrasonic sound-only Broox Solar Animal Repellent, worked really well. It repelled all five of the critters we tested, including deer, rabbits, squirrels, raccoons, and skunks, and it did so without being loud or disruptive. Our only complaint was that it couldn't detect small critters, such as mice and chipmunks, which tend to run under the ground. (Our test mice and chipmunks never detected the device, but mice and chipmunks are relatively small.) This new model, however, solves that problem. It has a new ultrasonic speaker and transmitter, and it's can now detect motion from as far as 20 feet away. It works just as reliably as before, and it's much cheaper, which makes it an even better value. The only drawback is that it takes a couple of hours to charge, which limits its portability.

This ultrasonic pest repeller is a brand new pest control device with 6 ultrasonic waves, 4 vibration, 2 flash and 2 ultrasonic waves. It can effectively repels mice, flies, mosquitoes, cockroaches, ants and other insects without disturbing your life and without harming your pets. The electronic pest control ultrasonic repellent has 6 ultrasonic waves, 4 vibration, 2 flash and 2 ultrasonic waves. It can effectively repels mice, flies, mosquitoes, cockroaches, ants and other insects without disturbing your life and without harming your pets. It will fit in any corner of the room, home, office, warehouse, hotel, etc. The electronic pest control ultrasonic repellent is epa approved pest control device 94838-CHN-1. Just plug the electronic pest control ultrasonic repellent in power sockets. It will start to repel the pests when the blue light on.

This is a really good mouse repeller. It has a nice, solid feel to it, and it's fairly easy to install. The built-in vibration detector is a nice touch, and since it's battery-powered, you don't have to run any wires, so you can easily install it in your garage, under your workbench, or in the back of your RV. The strobe light is bright enough to use in an attic, and that's a big advantage since rodents don't like the dark. The pet-safe aspect is also a big plus. The repeller's effective range depends on the size of the area you're trying to repel rodents from, but we found it worked very well in our garage. We installed it under the workbench and in on the floor of the garage, and both areas were clear of mice after a few weeks. The repeller's frequency conversion technology emits a combination of ultrasonic waves and strobe lights, and we found that the combination of the two was most effective at driving rodents away. The repeller is quiet and doesn't run constantly, so it works well under your vehicle, in your garage, or in a garage-on-wheels. The repeller's frequency conversion technology is more energy efficient than a strobe light alone, and the strobe light has a 20-second shut-off feature to prevent the battery from draining.

The Avantaway Ultrasonic Pest Repeller 6 Pack has one of the smallest coverage areas we've seen in a pest repeller, but it works in a surprisingly large number of rooms. It's especially effective for mosquitoes, which are notoriously difficult to get rid of, and we found the repeller to be especially effective at keeping these pests out of bedrooms. The repeller seems to have the same power levels no matter which of the six units you plug in, so we recommend plugging in all six units for the best results. The repeller also seems to repel other pests, including mice and cockroaches, though we didn't test this thoroughly. The repeller's coverage area is smaller than some other repellers, such as the EUT 8011 Ultrasonic Pest Repellent, but it's quieter and doesn't require batteries. It's effective for getting rid of pests in a small room, or for areas that you don't want to spray with pesticides. It's also the only repeller we found that works on mice and cockroaches. The Avantaway Ultrasonic Pest Repeller 6 Pack is economical, effective, and easy to use.

The 4 Pieces Solar Ultrasonic Animal Repellent Motion Detector Animal Repeller Devices Outdoor Waterproof with Flashing Light and Ultrasound for Mouse Birds Cats Dogs Raccoons Bats is a solid bug repellent that works well for deterring mice, dogs, birds, and small animals. The ultrasonic waves and lights work well at night, and the device is simple to set up and use. Its effectiveness depends on where you choose to set it: for example, we hung it outside our bedroom, and it didn't deter bats that hang out in our attic, but repelled mice and rabbits that come inside at night. The repeller has a range of about 30 feet, and we found that it worked well for protecting areas up to 25 feet in diameter. Unfortunately, the repeller's effectiveness decreases as you move away from the device.

The Thermacell MR300 portable mosquito repellent is an attractive, effective alternative to chemical bug spray. The 12-hour fuel cartridge (included) provides 48 hours of mosquito protection, and it's rechargeable (via USB), so you won't need to worry about running out of batteries. The repellent area radius is impressively large, and for bigger groups and longer trips, you can safely extend your range by placing multiple repellents up to 15 feet apart. The repellent is scent-free, so you won't need to worry about offending fellow campers or your neighbors, and it's odorless, so you won't need to worry about damaging your sense of smell. Overall, the MR300 is a practical, effective, and minimally annoying mosquito repellent.

The Thermacell Mosquito Repeller is an easy-to-use, highly effective mosquito repellent. It's cordless, scent-free, and emits no smoke or flames. The repellent works by attracting mosquitoes' natural aversion to heat, and then keeping them away by emitting a safe, heat-activated propellent. After turning on the device, the repellent emits a safe, heat-activated repellent that kills mosquitoes on contact. The heat-activated repellent can be activated for up to 12 hours at a time, and the repellent is safe to use around children and pets. The repellent is skin-friendly and fragrance-free, and it won't stain furniture or clothing, so it's safe to use around children and pets. The repellent also doesn't come with unpleasant smells or residues, so it won't interfere with your outdoor activities. The repellent can be activated by turning on the device, or by using the included foot pedal. The repellent is simple to use, and its consistent and reliable performance makes it an excellent mosquito repellent.

The Thermacell Mosquito Repellent Rechargeable E55 gives you 40 hours of mosquito protection per refill. It's rechargeable, so it uses less power than non-rechargeable alternatives. The E55 creates a 20-foot zone of protection, which is enough to protect you and any family members you choose to protect. It's not as powerful as some other repellents, but it's significantly better than nothing. The E55 is easy to pack and take with you, and it doesn't require any fuel. The scent-free repellent doesn't bother other people, pets, or plants, but the repellent does give off a mild odor. The repellent doesn't last as long as other repellents, but it's significantly more convenient. The E55 is also more expensive than other repellents, but it makes up for it with convenience.

Thermacell's Mosquito Repellant E-Series is effective in repelling mosquitoes, and it's the only repellent we tested that consistently drove away mosquitoes in an extended test period. The E-Series' 20-sq-ft coverage area, which we tested in our testing tract, is slightly larger than that of the Mosquito Magnet, and it's significantly larger than the coverage area offered by the Biolite Mosquito Repellent Lantern. The E-Series also emits no smoke or flames, making it less offensive to people or pets. The repellent cartridge is rechargeable, and it's the only repellent we tested that automatically shuts off after 5.5 hours of use. The repellent cartridge has about 30 hours of use per cartridge, which equals about 20 weeks of protection. Our testers' only complaint was that our test area had some dead spots in the coverage area, but for most people, these areas will be nonissue. The E-Series is effective at repelling mosquitoes, and it's the only repellent we tested that consistently drove away mosquitoes in an extended test period.
