Now just entering autumn, the "afterglow" of summer is still there. In addition to mosquitoes attracted by people, there are often some small flying insects at home inexplicably, especially on the top of fruit bowls, sewer pipes and potted plants. They will appear from time to time. If they don't come, they will be in droves, which is extremely annoying. The vast majority of these small flying insects are called fruit flies. They exist widely in our living environment, but they are not easy to attract attention because they are small and silent. In outdoor environment, such as silted sewage ponds, drainage ditches, septic tanks, etc., after eclosion, adults can enter the room through floor drains, pool pipes, toilets, etc. and stop on nearby walls. From the growth environment, we can see that they contain many germs, which may pollute food and spread diseases.
Use white sugar and detergent to kill insects, use 84 disinfectant to kill insects, use traditional Chinese medicine to drive out insects, keep indoor hygiene and prevent insects.
Different fruit flies have different food habits, and some often suck molasses on mature fruits or rotten plants to get nutrition; Others feed on tree sap or pollen, and their main food is yeast which can survive under aerobic and anaerobic conditions. Drosophila can lay eggs under the skin of fruit, but most of them grow up in pollution-free environment and rarely carry germs, so they generally do not harm human body. However, fruits that have been stored for a long time, especially some fruits that have been peeled, may also be contaminated with other bacteria in the environment, and it is recommended to eat them now.
