we all know that in today’s busy world technology is very important in society, because it makes life easier to live on and less time consuming, for example when you are back to home after a very tired day and you get irritated by insects and some rodents, we need something to deal with them without wasting our time so today I would like to introduce you with an electronic device which is solution to these irritating problem. I am talking about ULTRASONIC PEST REPELLER also popular as UPR. It is designed in such a way that it makes sound of frequency more than 20,000 Hertz, which can not be heard by Human Beings, but it is audible by pests ( insects, arachnids and rodents) and those frequencies are manipulated in such a way that it effects pests negatively, driving them crazy. Due to the frequencies being out of the audible range of human ears it does not affect us. Studies and researches on these types of devices have shown to be ineffective and harmful to its users.
The hypothetical theory behind this device is , that it uses short wavelength and high pitch sounds that are unheard by human ears due to some physical limitations of our ears, though there is some variations between individuals at such high frequencies. Many species of insects and animals can detect such high frequencies of soundwaves. Some insects like grasshopper and locusts can hear frequencies from 50,000 Hertz to 1,00,000 Hertz and some species of bats can hear frequencies even more than 2,00,000 Hertz which is a contradiction to the point that birds can not hear high frequency (ultrasonic) sounds.
Now a days many softwares and smartphone applications claim to repel insects and mosquitoes by using this technology but this can have some negative effects too. All the hardwork behind this project has resulted uneffective and waste of money.
Pests like rodents and insects transmits salmonella, hantavirus and other diseases as well as they can cause physical damage to your household things. Signs of rodents infestation include droppings and holes and structural materials that can provide entry of other pests into the home. There are many ways to tell if your home is full of pests or not like cockroach which is arguably the most pervasive and hard to eliminate type of pest especially in urban areas and industrial and commercial kitchens leaves behind droppings as well as egg sacs which are often spotted in hard to reach locations such as cracks and crevices in kitchens, cabinets and drains etc. Ultrasonic Pest Repellers are claimed to eliminate even these types unwanted household pests.
The use of high frequency sounds to deter pests is an old strategy, the ancient Chinese used a number of mechanically operated pest repellent devices to deter rodent infestations in agricultural crops and buildings. These types of devices has been used as pests control only over past few decades.
The high frequency sounds that are disruptive to pests can cause psychological responses which are known as audio genic seizure response which is characterised by non-directional running , convulsions and possibly death from cerebral haemorrhage. The theory behind these devices is that the confused pests usually flee when the disruption prevents them from gathering food, breeding and building nests. These types of ultrasonic devices are popular to customers because of their ease of use and the in audibleness of these sounds to human ears and it eliminates the need of traps and poisons which are considered to be inhumane forms of pest control.
In my point of view any type of ultrasonic pest controller are harmful for humans non effective towards pests and a waste of both time and money. So we should not get engaged in these of fake products and scams popular in market.
