Do ultrasonic rodent repellents really work? The short answer is no, ultrasonic rodent repellents don't work.
Ultrasonic rodent repellents may work temporarily to deter rodents, but they are not highly effective in the long term. Rodents can get used to the sound, and the devices may not work well in large or cluttered areas.
Does Plug-In Pest Free work? Yes. Plug-In Pest Free has been scientifically tested in a leading Australian University against rats and mice (full 2 year study). It has been independently tested over a two-year period by a leading multi-national supermarket company against rats, mice and cockroaches.
However, the noise will not penetrate walls, you can still use these products in your home as long as your pets are not in the same room as the repellent. There is some confusion over whether or not these can be used to repel insects.
The two best ways to remove rats are traps or poison. The use of either requires caution!
Sound to make if you come face to face with a rat
Stomp your feet: stomping is certainly less effective if you are in a carpeted area of your home or outside on your lawn, however, in the right circumstances, a loud stomp coupled with the vibrations through the floor can be an effective rodent deterrent.
Some are sold specifically to repel rodents. However, there is little data that these devices repel insects or are effective in rodent control. Rats and mice emit high-pitched sounds and may communicate using these sounds. Devices that use sound that humans can hear typically have no effect on the rodents.
With shapes and options fitting for virtually any nook or cranny in your home that has an outlet. Pest Repellers work right away but please allow 2-3 weeks in order to see optimal results and to enjoy a completely pest free space.
While cats and dogs can hear the ultrasonic waves, the ultrasonic repeller do not generally harm or distress them. The sound being emitted would have to be rather loud to affect an animal as large as a cat or dog.
Mice, rats, and even ants can be repelled with peppermint spray. No doubt. But it's where they go after that is a bigger concern. Spraying peppermint oil in your kitchen might repel a mouse away from your kitchen– but it might just go back to living in your crawlspace or attic.
Despite popular belief, mothballs are not an effective solution for deterring mice. While these pesticide products contain strong smelling substances like naphthalene or paradichlorobenzene, their efficacy against rodents is minimal at best.
Outdoors, rats face a variety of predators. In these environments, large birds of prey — including hawks, falcons and owls — feed regularly on rodents. Owls are particularly formidable predators, as their nocturnal behavior ensures that they are most active when rats go out in search of food.
Rats will not leave on their own unless they are forced to do so by humans. If you give them a chance to leave on their own they will eventually die from lack of food or water or because of disease or other circumstances that could kill them off quickly before you get rid of them completely.
To remove rats from your environment, you must remove the food, water and habitat that are supporting rat populations in the first place. If you continue to provide food, water and habitat while trapping and poisoning rats, you are creating a never ending cycle of attracting and killing rats.
In summary, ultrasonic pest repellers emit high-frequency sounds that manufacturers claim reduce household pest infestation, but laboratory tests have shown that the majority of such devices do not work as advertised, in violation of FTC guidelines.
In a room with mostly hard surfaces, like a kitchen, ultrasound will "bounce" around giving coverage that is more effective. The ideal placement would be one that allows the sound waves to cross in front of an entrance way.
Peppermint oil — Essential plant oils like peppermint, rosemary, citronella, sage and lavender have strong botanical scents that rats dislike. One customer successfully repelled a rat by stuffing a peppermint oil soaked tissue into the rat hole chewed into the wall.
It's possible to repel rats using essential oils such as peppermint oil and other smells that they naturally don't like. Using peppermint oil is one of the easiest ways to keep rats away from your home as long as you aren't giving them an easy food source.
Rodents do not like the sharp scent of vinegar, so it's believed that it can be an effective rodent repellent. Common advice is to soak cotton balls with vinegar and place them near areas where you think rodents are entering your home and to use vinegar as a cleaning solution.
Rats and rodents in general are very sensitive to sound, since it's one of their main tools for survival. Any new or unexpected noise will frighten them and send them scurrying. However, once rodents get used to a sound, they will no longer fear it.
While rats can be difficult to get rid of, there are some effective and natural ways to deter them from your garden. Some of the most effective natural rat deterrents include crushed pepper, peppermint oil, cayenne pepper, black pepper, cloves, citronella, eucalyptus, and chilli flakes.
