Ultrasonic Pest Chasers – Best way to repel mosquitoes

Ultrasonic pest repellers are the devices used as a substitute for avoiding inhaling toxic chemicals and fumes of mosquito killers and repellents. It is the non poisonous method of repelling pests responds to the ultrasound. Ultrasound is the highest frequency and powerful waves and is not sensitive to the human ear because a human ear can respond only in a frequency range of 20 Hz to 20 kHz. But, animals such as dogs, cats responds to 22-25 kHz, rats to 60-72 kHz and insects such as mosquitoes and flies responds to 38-44 kHz. Ultrasound can travel along a straight path when it hits an object; it bends and spread in all possible directions. Animals can produce ultrasounds as well as respond to ultrasound because they have sensory structures like tympanic membrane for detection and they also communicate each other by using ultrasound waves. Mosquitoes have sense organs to produce and receive high-frequency ultrasound waves. Spiders, wasps, beetles, flies, spiders, lizards have the capacity to detect ultrasound. These detectors are found in the antennae of mosquitoes and genitalia of cockroaches. Ultrasonic pest repellers emitted these sound waves will create pressure on the nervous system of the insects and animals and this will confuse them and finally they escape from the source of high-frequency wave device. These devices are greatly used for to repel various disease causing insects, rodents from a particular area. Ultrasonic high-frequency waves are also widely used for scanning in hospitals. Moreover, these sound waves will not pass through the walls like the sound waves. According to the literature and scientific research it is considered as safe and will not cause any damage to the human health, however, ultrasonic frequency near to 30 kHz can be detected by the kids up to a certain level, so it is advised not to use these ultrasonic chasers continuously near the children under the age of 5 years.


Response Behaviour of Animals Towards Ultrasound

  • 22-25 kHz: Dogs, Cats
  • 38-44 kHz: Mosquitoes, Fleas, House Fly, Spiders, Cockroaches
  • 52-60 kHz: Lizards
  • 60-72 kHz: Rats

Profit makers are ready to poison people at any cost

Due to several health benefits, milk is considered as a complete food that contains all the vital nutrients. Earlier, every person drinks the purest milk and so, extracts many nutrients from the milk. But, we cannot get the essential nutrients from the contaminated milk, whereas, drinking of pure milk is just like a dream now a day’s. Milk is lacking so many healthy nutrients and further some more nutrients are also eliminated during the processing methods in the milk dairies. Moreover, dairy cows are injected with a chemical named oxytocin, a hormone that used to increases the production of milk in cattle. Oxytocin or Pitocin injections are given to the pregnant women for inducing artificial labor, but commercially oxytocin injections are used over the cattle, two times in a day, in tabelas. After injecting the chemical hormone, the stored milk in the udder of the animal released, and giving extra liters of milk. This hormone contracts the uterus of animal causes severe pain each and every time when it is injected into the cattle’s body and its prolonged use causes neurological problems, difficulty in conception that may lead to infertility and with regular use, the cattle loses the control over udder which gets inflamed and infected with the pus and reduces the life expectancy. However, the government of India has banned the use of oxytocin injection on animals because of its several negative health issues under section 12 of Food and Drug Adulteration Act, 1960 and the Prevention of Cruelty to Animals act. But the rules and regulations exist only on the papers because the milkmen, villagers, and farmers do not follow the regulations and still grabbing the profit by getting the injections from the chemist’s shops without any prescriptions of veterinary doctor and it is quite miserable in India. The injected oxytocin reaches into the human body through the consumption of milk and causes several side effects in men, women and children, such as- Early puberty in girls, Gynecomastia (female-like features in male), Hormonal imbalance in children, cardiovascular problems, including cardiac arrhythmia, increased or decreased blood pressure, premature ventricular contraction etc., irregular monthly cycle in girls and women, loss of vision, renal diseases, memory loss, breast cancer and also impotency in males.


Milk dairies do not perform this test, however; boiling before consumption is the best option in order to reduce the traces of oxytocin. To minimize the negative effects of oxytocin boiling of even pasteurized milk is recommended.

Fight against milk Adulteration

Adulteration of milk is a serious problem due to which the whole population is in a great danger. The Indian population is increasing day by day and simultaneously the farmers are leaving the profession of farming milk animals from the same rate. Then where do we get our demand fulfilled. At this stage, profit maker invented the various adulteration techniques to fulfill the need of the innocent people. Further, the milk products made from the adulterated milk are even much more dangerous.

milk adulteration

Addition, mixing, substitution of cheap and unwanted toxic ingredients to the food is called as food adulteration. This addition may be intentional or unintentional to increase the profits. Earlier, to increase profits water is one of the common adulterant used in case of milk, but, consumers immediately trace out its presence, as the addition of water changes the taste of milk, further, the formation of layers of cream over the milk after boiling is also reduced. Consumers also check the presence of water by conducting the drop test. To avoid catching, the profit makers start adulteration of some cheap substances such as, formalin, urea, starch, neutralizers, detergents, sodium chloride, skim milk powder, sucrose, glucose/dextrose, hydrogen peroxide and refined oil to the watered milk to develop the proper thickness, taste, missing fats, density, and viscosity.

According to some reports, detergents found in the tested milk samples of a famous brand and now it is very important to know about the milk (a super food) that we are consuming and giving to our children in the hope of their proper growth and development. Detergents are responsible for food poisoning along with gastrointestinal complications and all the synthetic chemical ingredients disturb the functioning of different vital organs of the body by causing cardiovascular problems cancer and even death.

Collected milk and milk samples from various places loaded with different proportions of adulterants that can be detrimental to the human health; furthermore, a governing body should be regular checking the milk and milk products for the estimation of these toxic adulterants. Now it is the right time to make stronger law and to take a strong and serious action against the adulteration of milk. Awareness should also bring to the innocent consumers by providing the information regarding the analysis of milk and the hazardous effects of these harmful chemicals as milk and milk products play an important role in Indian cuisine.

Is it safe for consuming pasteurized milk without boiling?

Milk is considered as a powerhouse of the vital nutrients. Its regular consumption plays an important role in the overall growth and development of healthy bones and teeth in the human body. Raw milk carries several harmful bacteria responsible for food borne illnesses like diarrhea, vomiting, stomach infection, kidney failure, paralysis attack and much more. The symptoms can be different, from person to person, that totally depends upon the type and strain of microorganisms, the amount of contamination and weakened immune systems. Infants, kids, weak peoples, old age people are more susceptible to the food borne illnesses and they even can die due to the consumption of raw milk contaminated with Brucella, Campylobacter, Listeria, Mycobacterium Bovis, Salmonella, E. coli, Shigella, Streptococcus pyogenes, Yersinia enterocolitica and much more.

is it safe to drink milk without boiling

That’s why maximum people used to consume boiled milk because boiling destroys bacteria along with other organisms and it also increases the shelf life of milk. Boiling of milk does not eliminate all the microorganisms but is an effective and important way of killing the spores of microorganisms. However, some nutrients are also lost during boiling of milk, especially B group of vitamins (water soluble). So, it is recommended, not to boil the milk at very high temperature for a prolonged period of time.

Pasteurization is a process that destroys the harmful microorganisms by heating milk at a temperature of 72 ̊C for 15 seconds. Pasteurization was first discovered by the French scientist Louis Pasteur in 1864, pasteurization destroys the harmful organisms responsible for the illnesses such as listeriosis, typhoid fever, tuberculosis, diphtheria, and brucellosis. So, it is unsafe for consuming unpasteurized milk, cream and other dairy products like ice-cream, puddings, yogurt, soft and hard cheese made from pasteurized milk, therefore, it is better to ask from the grocer or storekeeper about the pasteurized products.

According to some research, there is no difference in the nutritional values of pasteurized and unpasteurized milk. Pasteurized milk is not the ‘sterilize milk’; hence, there are some of the chances of survival of temperature resistant bacteria and their spores. Pasteurized milk needs the temperature of 4 ̊C for maintaining the cold chain facility storage, which assures the milk is fit for consumption until it reaches to the consumer. If the temperature raises greater than 5 or 6 ̊C, the further growth of the bacterial spores would start that reduces the shelf life of the pasteurized milk. So, it is necessary to maintain the low-temperature storage facility and further, it is also advisable to boil the milk and refrigerate it immediately for the reduction in the growth of bacterial spores in order to extend the shelf life.

Silver coated sweets- May contain toxic Aluminium

Silver foil also known as Chandi varak, are the edible silver leaves with no flavour and are used for garnishing the sweets in South Asian cuisine. It is generally used in India for decorating sweets, confectionery, desserts, and dry fruits like almonds, cashew nuts, and dates. In the market, cardamom- coated sweets are also commonly available. These leaves are not specific to the Indian cuisine, but Japan and European countries are also used this precious metal leaf to garnish food, and as an additive in special drinks. Varak is made of pure metal such as silver for silver foil and sometimes gold is used to prepare gold foil. For the preparation of varak, intestines of the cattle/ox are used because of its great elasticity that cannot be cut after a severe beating. It can be obtained from the slaughtering houses and further, its separation is much easier from an animal tissue than to separate from any other paper technology.

Silver coated sweets- May contain toxic Aluminium

The intestines are pulled, washed in the slaughtering houses in order to remove blood and other remains of the intestine and given to the varak manufacturers. These intestinal guts are cut into the smaller pieces, blocks of silver is placed in between the bound layers of the intestines and keep this in a bag of leather followed by sealing. This bag is then beaten, with the help of wooden sticks, until the silver block is flattening out and turned into silver foil. This foil is separated from the intestinal pack and will be placed on papers. The prepared extremely thin leaves are brittle and break into smaller pieces and get stuck to the hands. These are odourless and tasteless that is why these are used for garnishing purposes to enhance good appeal which shows a symbol of royalty and prosperity for the family. Gold and silver food leaves are certified by the European Union, as E175 and E174 additives respectively. These are safe with purity near to 100% with 0.1% standard deviation, but it is extremely difficult to check the purity and that is why the manufacturers are making ‘profit’ by compromising the quality of the leaves. India has the great market for vark but do not have any control regulations in order to check the quality of these edible ‘foils’. Several cases of ‘poor’ quality of silver and replacing of silver foil with aluminium foil have been reported. So, precaution must be taken while enjoying the silver coated sweets because consumption of these low-quality sweets causes severe illness in the body. The easiest way to check out the difference in between the two- aluminium leaves residue get stuck to the hands on wiping the top layer of the sweet.

Negative effects of consuming silver leaves:

  1. The preparation process of silver foil may leave the traces of blood and flesh on the leaves.
  2. The manufacturing process is highly unhygienic and unhealthy.
  3. There are chances of contamination are high if the leaves prepared from the infected and diseased animal.
  4. Consuming this causes throat and lung problems, stomach pain and several infections.
