Having a pest infestation can be very frustrating.

These creatures can cause significant damage to health and property if not properly controlled. If you hate using chemicals within your home to control pests, then you might consider opting for an ultrasonic pest repeller.

However, are these devices safe for humans?

If you have ever considered using these devices, this guide will provide an insight into these ultrasonic repellents.

Now, let’s take a dive in!

What is an ultrasonic pest repeller?

An ultrasonic pest repeller is an electronic device that controls pests by emitting a high pitched sound that may irritate, annihilate, or repel household pests.

In other words, this ultrasonic pest repellent releases sounds that pests cannot tolerate and this drives them away. These devices are generally safer and easier to handle with respect to most pest control options. Using these devices might involve plugging them into an electrical outlet.

Yet, some employ the use of batteries that ensures their easy use in gardens, fields, and other areas with no electrical outlet. When these devices are turned on, they emit high-frequency sounds, which is beyond the range of human hearing even though some people with very sensitive hearing may perceive them.

Are Ultrasonic pest repellers bad for humans?

Ultrasonic pest repellers represent one of the easiest and fastest ways to overcome pest invasions. For homeowners with multiple issues with rodents, cockroaches, and other pests, these devices have been proven to be effective in repelling these pests.

It has been proven by a group of scientists that research conducted proved that these devices – on human ears after a prolonged exposure – produced negligible adverse effects.

In other words, there was no reaction in humans.

Besides, since the human ear cannot perceive this sound, the presence of these devices is insignificant.  You should understand that reading reviews allows you to know more about a product from the perspective of those with prior experience.

A product from a reputable manufacturer will most likely provide a good value for money since it is made from high-quality materials.

Are Ultrasonic pest repellers safe for your pets?

It is only natural for you to protect your pet when you have one in your home.

It is generally believed that these devices are safe for your buddies. Oftentimes, dogs and cats can perceive waves of high frequency.

However, in most cases, these animals are not affected.

If you notice your pet barking or make a reaction towards this device, you should move it to another place where the pets would have no access to it. If this continues, it might be due to neurological sensitivity. This shows that the pet is in distress.

To protect your pets, you might consider removing these devices from your home. Smaller pets, including guinea pigs, hamsters, and pigs can perceive these sounds and this can make them distressed. For this reason, you should keep these devices from your pets.

Other pest control options

However, adopting other pest control options is not a wrong idea, especially when these devices do not give you the preferred results.

Hiring a professional in pest control will not just help you remove all pests from your home, but there will be relevant tips that you can learn on how to manage these pests properly to ensure that they do not become uncontrollable problems for you.

Some of these include:

  • Sealing all cracks that may lead directly into your home.
  • Understanding how these pests behave to know how to deal with them. This may include modifying the landscape of your home with the hope of making it uncomfortable for these pests.
  • Eliminate all food sources, which may attract these pests, in your home and surroundings.
  • Eliminating all hiding spots that may serve as hiding spots within your home where they can live and reproduce.

Consider the location

It is important to think of the areas within your home you suspect any form of pest activity. Some signs to watch out for include droppings, small tracks, gnaw marks, among others. After this, ensure that you place these devices in a way that opens up to the other parts of your room.

In doing this, you must understand that surfaces that reflect ultrasonic sound waves (hard surfaces) will enhance their propagation while surfaces that absorb ultrasounds will impede their transmission.

Combine with other pest control techniques

An ultrasonic rodent repellent device can be combined with other methods to get the most effective result.

Maintaining proper hygiene, as well as using traps, can be an effective means to control pest infestation within your home. Once you’ve managed to get pest infestations under control, using these devices can be very effective in keeping them away.
