There are mixed opinions on whether ultrasonic rodent repellents actually work but if you are looking for an expert opinion; no serious licensed exterminator would use, let alone recommend these gadgets.
Ultrasonic rodent repellents are plugged into electric outlets near areas with high rodent activity. The device emits ultrasound (exceeding 20,000 Hz) which is virtually undetectable to the human ear but presumably causes convulsion, confusion and/or death to rodents. The premise is the ultrasound will keep rodents away from your home. This idea seems to be based on the fact that Chinese farmers used similar, but rudimentary manually-operated devices for rat control to keep rodents and pests away from crop fields.
Why Ultrasonic Repellents Don’t Work
From a factual point of view, there is simply no conclusive evidence that these devices work. There is no independent study that seriously supports the claims made by manufacturers of these products.
Another fact that the manufacturers neglect to mention is directional sound emitted by these devices does not travel through walls and other such obstacles. If, perchance, these devices actually worked; their effectiveness would be severely limited by the layout of the average home. Rodents can simply nest in ‘safer’ parts of the house where the offending noise cannot reach them.
Finally, claims that ultrasonic noise repels rodents are not completely unfounded. Rodents are cautious creatures and generally keep away from unfamiliar sounds, sights and smells. These animals are however highly adaptable and will soon get used to the sound. If at all effective, such a device would only be a short-term solution.
Call a Professional Exterminator
Poisons and baits are far more effective for rodent control than any device you could plug into a wall. DIY extermination has a high failure rate because laying poisons and traps successfully requires intimate knowledge of rodent activity. This helps to identify areas of high activity and to place baits, traps and poisons accordingly.
Using poisons and traps also puts your young children and pets at risk especially if you do not know how to these products safely.
Hire a professional, licensed exterminator in Canada to get rid of rodents. The professional will identify the type of animal before using the most appropriate extermination method. The exterminator is also responsible for thorough cleanup and disinfecting the home to discourage other pests from coming in and eliminating the risk of contacting a disease from the rodent’s nest, feces and urine.
Lastly, only a professional can help you identify all the possible rodent entry points and seal them accordingly. Ask for a warranty of at least 6 months to ensure that the extermination was successful.
