In some countries, because of the poor economic situation and the little attention of the environment. The sanitary status of the countryside is worse than city. In addition, the sheep farm, pig farm and livestock farm will provide survival conditions for some pests. The countryside is generally located in an environment with lots of vegetations, at the same time, the presence of paddy fields and stinking ditch makes the development of mosquitoes and flies very rapid. In addition, the hoarding of food also has huge attraction to mice. These pests have had a significant impact on people's lives and agriculture. As people's living standards improve, people are slowly beginning to pay attention to and try to solve these problems.
However, it seems that people do not have a good solution for these problems. The most efficient and widespread method of repelling mosquitoes and flies in rural areas is to spray insecticides and set rat bait stations, which are cheaper and more convenient than high-end products, but these methods also have flaws. As an open environment, if you want to maintain a mosquito-free state for a long time, you should always spray insecticides, and the cost will be expanded limitlessly. The common rat bait stations in the countryside are often open-ended, which not only makes the rat poison damp easier and lose the effect, but also easily eaten by the animals around. Traditional mouse traps maybe accidentally hurt other animals, and the died mouse will pollute the grains.
