Commercial ultrasonic pest repellers are designed to emit ultrasound in the frequency range 20 kHz to 100 kHz. Ultrasound above 20 kHz is inaudible to man but children can hear the ultrasound to a certain level up to 30 kHz.
Most ultrasonic pest repellers emit sounds above 20 kilohertz (kHz). Rats, mice, hamsters, and other pet rodents can hear sounds up to 90 kHz.
Most homes need quarterly pest control to handle common pests like termites and fleas. Homes with more pest activity should have bi-monthly or monthly treatments for better protection. The type of pest, the size of your home, and the severity of the infestation can affect how often you need pest control.
When it comes to regularly scheduled pest control, we suggest having your home treated once a quarter or every two to three months.
Ultrasonic frequencies tend to be the most detrimental. They hate frequencies around 22-25 kHz US . Insects like Mosquitoes, Flies hate frequencies around 38-44 kHz.
The Pest Control Repeller uses sound waves to repel pests from your home. The different sound frequencies (20 to 40 kHz) prevent pests from getting used to the pulses and staying in your home. It's the safest and best alternative to chemical repellents, poisons, and traps that can harm people.
UHF-4 Band - A major band break for the UHF band is between 400 and 420 MHz which is used by many eavesdropping devices. UHF-5 Band - The next band break for the UHF band is between 420 and 450 MHz. The band is quite popular with a great deal of usage around the 433 and 434 MHz.
Good hygiene, tidy housekeeping and effective insect exclusion will generally discourage vermin.
Not really; at most, they'll disturb pests temporarily. The idea is that pests will hear an annoying sound in your home and decide not to stick around. However, many pests like rodents and cockroaches are extremely adaptable to their surroundings and won't stay away for long (or at all).
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.
However, the question remains: Are these ultrasonic devices an effective pest control method? The answer in our experience: Sadly, no. There are several reasons for the failure of these devices for pest management purposes.
According to the producer, the most effective frequency range lies between 10 and 12 kHz for birds, between 20 and 30 kHz for rodents, and between 30 and 40 kHz for insects.
Non-chemical methods of controlling pests are often very effective. Some examples of non-chemical control methods include trapping, heat treatments, cutting or mowing, or cultivating soil. Chemical controls can be an effective part of IPM, but are just one of the many tools that may be used.
Why can't I hear the Ultrasonic Rodent Repellers™? Ultrasonic sound is a frequency too high to be heard by the human ear (your eardrum cannot vibrate fast enough).
Existing studies indicate that mosquito pests can be expelled with the frequency of 18–48 kHz. But this still cannot eliminate mosquito larvae that require a wave of 85 kHz.
Termites mortality was 100% both at frequency 300 KHz and frequency 500 KHz and both in 30 minutes and 60 minutes irradiation time.
As per scientific information and experimental evidences, the animals respond to ultrasound and avoid its presence. Small mammals like Dogs, Cats etc. hate frequencies around 22-25 kHz US and Rats to 60-72 kHz. Insects like Mosquitoes, Flies hate frequencies around 38-44 kHz.
Integrated pest management (IPM) is widely recognized as the most effective and least toxic method for managing pest control issues.
Every enclosed workplace shall be so constructed, equipped, and maintained, so far as reasonably practicable, as to prevent the entrance or harborage of rodents, insects, and other vermin. A continuing and effective extermination program shall be instituted where their presence is detected.
To be specific, pest control is recommended every two or three months for a regular home or busy workplace.
The frequency range of RF signals is generally between 300 kHz and 300 GHz. It is widely used in radar and wireless communication. RF-based eavesdropping attacks are an attack method that uses radio frequency signals to listen to other people's communications or obtain sensitive information.
Warning Signs of Being Bugged
Finding items in your home or office that seem to have moved without explanation could indicate unauthorized access. Electronic devices behaving erratically, such as sudden battery drain, unexpected shutdowns, or strange pop-ups, may also suggest external interference.
Every listening device will appear slightly different, but they'll usually look like the following: Very small and round, usually no more than 0.5 inches (1cm) Black or silver plated, with a hole in the center. Similar to a small microchip.
