Definitely, mosquitoes are annoying and it can spread diseases also. The best way to destroy mosquito is electronic killing using Swatter. It eliminates the use of toxic chemicals. The mosquito coils and liquids do not kill mosquito but they repel them only. Mosquitoes will return back when the chemical disappears from the atmosphere. The swatter is commonly called as Mosquito racket and is meant for killing the mosquito and not for repelling. Since each mosquito lays thousands of eggs, destroying a mosquito equals destroying thousands of mosquitoes.
Some Mosquito Biology
There is no doubt, mosquitoes and mosquito bites are annoying. The nuisance mosquitoes bother people around homes or in parks and recreational areas and everywhere. They reduce real estate values, adversely affect tourism and related business interests, or negatively impact on livestock or poultry production. Above all these, mosquitoes transmit fatal diseases like Dengue fever, Malarial fever, Filariasis, Chikungunya, Encephalomyelitis etc.
Swarming in Mosquito
Mosquitoes are Crepuscular (Twilight active- Evening and early morning) and they show mass migration (swarming) in places where human beings are located. Mosquito has feeble flying ability so that they can fly only 10-20 meters distance and up to a height of 20-25 meters. They usually fly above the ground level around 2-3 feet. That is why we get more mosquito bites in the legs. Mosquitoes prefer legs since they get sufficient blood from the legs, because the veins in the legs are large and are located just below the skin. The mosquitoes biting us are the members of the local population . That is, the mosquitoes reared in our own home. Mosquitoes from long distance will not migrate to our home for biting.
Male mosquito produces characteristic ultrasound vibrations to attract females. After mating, female mosquito avoids the presence of males by detecting the ultrasound from males. This is the principle in Ultrasound mosquito repellents that produces 22-38kHz ultrasound to simulates the sound of male mosquito. The female mosquito considers the device as a male mosquito and avoids its presence.
