These sound waves are typically above the range of human hearing, making them inaudible to people but disturbing to certain pests. These repellers claim to create an environment that pests find uncomfortable, encouraging them to leave the area or avoid it altogether.
HOW DO ULTRASONIC PEST REPELLERS WORK? Ultrasonic pest repellers emit frequencies above the threshold for human hearing (above 20 kHz) in an attempt to scare off pests without bothering your ears. Imagine walking into a home and hearing a loud, high-pitched tone playing incessantly—you'd probably walk right back out.
Silent (ultrasonic) devices are not heard by 96% of humans but are very irritating to birds. Our devices operate at a frequency of 15-25 khz and some of our commercial products as much as 30 khz.
How to Tell If Your Pest Repeller Is Working. 1. Reduced Pest Activity: One of the first signs is a noticeable decrease in pest activity, such as fewer sightings or droppings.
The red indicator light on the front of the unit will blink on and off to let you know that the unit is working. Please note that a slight "clicking" noise may be heard as the indicator light blinks on and off. This is normal.
Some common disadvantages of conventional ultrasonic sensors include limited testing distance, inaccurate readings, and inflexible scanning methods.
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.
It's common to see pests after treatment, which is usually a sign that the treatment is working. Often, bugs will come out of hiding once they are sprayed with a liquid solution because they are attempting to escape the source and will soon die.
Just plug a charger-sized device emitting undetectable sound into the wall, wait about 2 weeks, then BAM, your garage oasis is insect and rodent free without the use of chemical pesticides or inhumane traps.
Ultrasonic hearing is a recognised auditory effect which allows humans to perceive sounds of a much higher frequency than would ordinarily be audible using the inner ear, usually by stimulation of the base of the cochlea through bone conduction.
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.
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.
The devices are primarily marketed to repel rodents such as mice and rats, but some also claim to be effective against a variety of other pests, including insects like cockroaches and mosquitoes.
Do ultrasonic pest repellers affect Wi-Fi or household devices? We also get asked about the impact of these devices on other household items. While electric pest repellers do not affect Wi-Fi, they have been documented to interfere with telephone quality and reception of both landlines and cell phones.
The products can target and eliminate pest infestations without putting your family or pets at risk. This means that in most cases, you can sleep and reside in your home during and immediately after the treatments.
Why didn't your pest control work? Pest Control doesn't work for several reasons including: Improper mixing, inappropriate products for target pests, incomplete applications, sanitation, structural damage & resistance.
Some pests are active year round, such as ants and spiders, but other types may invade a home during inclement weather or in search of food. It can take several days or even weeks to eliminate a pest infestation completely, depending on how many pests are present and how serious the infestation is.
Ultrasonic devices cannot penetrate into or behind cupboards, drawers, wardrobes, furniture or walls where pests actually nest and breed. To effectively control insect and vermin activity by an ultrasonic device you would require one unit per room including one unit in the roof cavity to effectively control a home.
The theory of ultrasonic repellents is to create a sound irritating to rodents, but yet at a frequency out of the range of human hearing. Even though sound may be created that can be heard by rodents and not heard by humans, there is little data to support that these devices repel rodents.
Ultrasonic sound is not harmful to people and is inaudible to most. However, it can cause discomfort, annoyance, or non-threatening issues like headaches, nausea, tinnitus, especially to more sensitive individuals.
Ultrasound imaging has been used for over 20 years and has an excellent safety record. It is based on non-ionizing radiation, so it does not have the same risks as X-rays or other types of imaging systems that use ionizing radiation.
Explosion or fire may result. If the power supply is connected directly without a load, the internal elements may explode or burn. Be sure to insert a load when connecting the power supply.
