Is Pest Offense safe for humans?
PEST OFFENSE® is safe to use around humans, food, and most pets (it cannot be used around hamsters, gerbils, guinea pigs, chinchillas, and tarantulas).
Are electronic pest repellers safe for humans?
Pros: It’s a generally safe device to use because it doesn’t use any harmful or toxic chemicals. Unlike chemical pest control, repellers only use ultrasonic sounds to keep pests away from your home. They are safe to use around kids and most pets because they can’t get their hands into harmful chemicals.
Can ultrasonic waves hurt you?
There are two ways ultrasound can harm humans. The first is that it can heat up cells in the body, causing damage. The second is that ultrasound can cause “cavitation”. All sound waves are longitudinal – involving a cyclic pushing and pulling motion of molecules as the wave travels, called compression and rarefaction.
Is Pest Offense safe for dogs?
Helping Your Dog Cope with a Pest Repeller As mentioned earlier, these repellents will not cause any harm to your dog and, in many cases, will not bother your pooch at all. However, if you do have a dog that is quite nervous in nature, you may want to monitor its reactions and consider an alternative if necessary.
Can ultrasonic pest repellers cause hearing loss?
A recent study reported that exposure to ultrasound (between 20 and 40 kHz) damages hearing in the frequency range between 9 and 18 kHz. Damage may already appear after less than 5 years of exposure, and may be accompanied by other problems such as tinnitus (Maccà et al., 2015.
What sound frequency is harmful to humans?
The most dangerous frequency is at the median alpha-rhythm frequencies of the brain: 7 hz. This is also the resonant frequency of the body’s organs.
Can human hear ultrasonic sound?
An ultrasound is a type of oscillating sound pressure wave that has a higher frequency than human hearing is able to detect. An ultrasound is not a unique type of sound, therefore, but is classified differently due to the fact that humans cannot hear it.
Do ultrasonic devices harm dogs?
It is also advisable that you get rid of any ultrasonic repellents you might have around the house once you notice any signs of discomfort in your dog’s body language. Such devices can only harm dogs when the dog hears a really intense high frequency sound.
Do ultrasonic pest repellers really work?
The consensus from each study was that ultrasonic pest repellers have little to no impact on pest activity. The Federal Trade Commission (FTC) has also found that the claims made by some manufacturers are not backed by scientific evidence.
How much electromagnetic radiation is safe?
The FCC limit is 1.6 watts per kilogram (W/kg). All wireless devices sold in the United States are certified by the FCC that they don’t exceed FCC exposure limits. The FCC incorporates a safety margin in these limits.
Is RF radiation harmful?
Exposure to very high RF intensities can result in heating of biological tissue and an increase in body temperature. Tissue damage in humans could occur during exposure to high RF levels because of the body’s inability to cope with or dissipate the excessive heat that could be generated.
Can ultrasonic sound go through walls?
Ultrasonic waves behave more like light than sound. For example, music from your stereo can fill your entire house. Ultrasound cannot penetrate solid surfaces (walls, floors, ceilings) or travel around corners.
Does ultrasound affect health?
Although Ultrasound cannot be heard by humans, at high decibels it can still cause direct damage to human ears. Ultrasound in excess of 120 decibels may cause Hearing damage. Exposure to 155 decibels causes heat levels that are harmful to the body. 180 decibels may even cause death.
Does ultrasonic pest control really work?
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.
