Ultrasonic devices work by emitting high-frequency sound waves, which annoy rats and other rodents. Rats prefer quiet places so they will relocate to other areas upon hearing these sounds. Advisably, you should more than one ultrasonic repeller. In fact, you can set up one in each room. This way, the rats won’t simply move from your bedroom then start nesting in your basement.
Merits of Ultrasonic Repellents
Ultrasonic rat repellents are the most preferred because they don’t contain any harsh chemicals. Consequently, these types of repellents do not pose any health risks to humans or their pets.
Drawbacks of Ultrasonic Repellents
On the flipside, these repellents do not work as efficiently as other types. The high-frequency waves in some models fail to repel any rodents, allowing them to access your foods and other belongings. Moreover, the sounds emitted by these devices are meant to be inaudible to humans. Unfortunately, some ultrasonic repellents generated chirping or humming sounds that can be heard by homeowners.
Your pets may also be bothered by these noises and start fidgeting or become restless. Besides, ultrasonic repellents do not offer a completely green solution to rat control. Even though they don’t have any toxins, they need some form of electricity to function. So, if you’re an enthusiast of green techniques, you will have to look elsewhere.
Botanical Rat Repellents
This type of rat repellent is made purely from plant-based materials. The plants incorporated in these repellents deter rats from accessing your home. Most of the ingredients used in botanical rat repellents are essential oils, which are regarded as safe for humans.
How Rat Repellents Work
Rats are not only clever but also tenacious. They breed very fast, which is why they are used as subjects for a majority of experiments. For this reason, it is hard to ward off rats using rodent repellents alone. Keep in mind that they are not cowardly creatures that run off when they spot dry blood or human hair. Rats are particularly difficult to eliminate because they can even gnaw through wooden panels.
If you give them enough time, they’ll even chew through improperly-cured concrete. This does not mean that ridding your home of rats is impossible. It just means that you’ll have to be smarter than they are. For one, rats hate the smell of essential oils such as peppermint, lemongrass, cinnamon, and cedar. It is why most rodent repellent manufacturers like integrating essential oils as one of the ingredients.
Another active ingredient that deters rats and other rodents is thiram. Put simply, thiram is a type if sulfur fungicide, which prevents fruit trees from being invaded by rats. For the best protection, you should apply the garden repellent two times per year. Regrettably, no one rat repellent is capable of protecting your yard and home on a long-term basis. Even if you come across a repellent being advertised as long-lasting, odds are that the longest it can keep these rodents away is a month.
The same concept applies to ultrasonic rodent repellents. Although safe and eco-friendly, these gadgets have not been scientifically proven to repel rodents for good. Also, the frequency and intensity of ultrasonic repellents do not always correspond to the real output. Based on several studies, it has been found that increasing distance reduces the intensity of its contents.
What’s more, rats can get accustomed to the annoying sounds generated by these gadgets. On this note, it is safe to say that the best way to keep off rats is to combine both techniques, that is, an ultrasonic device and a botanical repellent. You will also need to perform routine checks to ensure that your home does not have any cracks through which rats can pass through.
