If you have young children and pets, dealing with an insect or rodent infestation can be a hassle and even dangerous. Noxious poisons and traps left around your house and yard could be a hazard, and replacement can be a hassle.
Instead, ultrasonic pest repellers produce electromagnetic and ultrasonic sound waves to confuse and irritate pests, causing them to flee. Some models plug into your home’s electrical outlets, while others use solar energy to charge built-in batteries to power their pest control.
What to Consider When Choosing the Best Ultrasonic Pest Repeller
From pest types to power sources, a little background about these products can go a long way when shopping for the best ultrasonic pest repellers. Be aware that the industry uses “repeller” and “repellent” interchangeably. While some shoppers might think of “repellents” as chemical dusts and sprays, for buying purposes, these can also be repellent devices.
Whether preparing your home to keep warmth-seeking mice or moles at bay as outdoor temperatures dip or simply tiring of creepy crawlies popping up overnight, you might find your solution in an ultrasonic pest repeller.
In general, these products address rodent issues within the home. If the issue is a mouse or rat problem inside, plugging one of these repellers into your outlets can help. Many of these pest control products are also effective against other pests, including squirrels, ants, cockroaches, mosquitoes, fruit flies, fleas, crickets, snakes, scorpions, and bats. Some models may even help you avoid a bedbug infestation.
When you have a garden, even the deer you love to watch can turn from endearing to pest, and some ultrasonic devices are effective deer repellents. You can even find some products that will repel dogs and cats from your yard. Just beware that these repellers can also affect your dog or cat, so be selective if you’ve got a furry friend.
For an ultrasonic repeller to be effective at pest control, you need it to provide sufficient coverage. Most of the best ultrasonic pest repellers provide somewhere between 800 and 1,200 square feet of coverage. While they may be effective in a wide-open basement, understand that your walls and ceilings can limit this range.
In this case, you may need a few of these pest repellers spread throughout your home for full coverage. A good practice is to place them in troublesome areas like the kitchen, near drafty doors, and in moisture-laden rooms like bathrooms. By placing two or three repellers throughout the home, the range of each will likely overlap, providing adequate coverage for most pest problems.
There are three main power sources for ultrasonic pest repellers: electric, solar, and battery power.
- Electric repellers work well in the home or garage. They are plugged into a standard 110V outlet so that you can cover a kitchen, garage, laundry room, and anywhere else you might have a pest issue.
- Solar pest repellers are ideal for driving pests from your yard. These repellers typically stake into the ground and soak up the sun’s rays with photovoltaic panels, converting them into stored energy.
- Battery-powered repellers are a great option for staying bug-free while fishing, hunting, or at an outdoor event. They use batteries to repel insects and rodents from camping gear and prevent annoying buzzing around your ears while reeling in the big one.
Ultrasonic pest repellers provide long-term coverage compared with other types of repellents designed to deter pests. Poisons, baits, traps, sticky traps, and dusts need replenishing from time to time (as often as once per week for a serious issue). Although weekly maintenance can be expensive and frustrating, most of the top ultrasonic pest repellers last for 3 to 5 years. They create the ultrasonic signal that repels pests, so they’ll work as long as they have power.
Most yard repellers get their energy from the sun. To be effective at night, they need to conserve their power until a pest arrives. In order to save a bit of energy, many models use motion sensors to detect movement and then emit sound waves rather than continually emitting them throughout the night.
There are also models with lights. Some work like night-lights, while others work as deterrents. The deterrent lights flash when they detect a pest, scaring it away from the yard. In some cases, these flashing lights may even double as an added layer of home security, alerting you to backyard intruders or larger, more dangerous animals.
