How do flies spend the winter?

Flies can be said to be a kind of creature that everyone hates. In summer, flies always fly around the food, which is very tiresome. It may also endanger our health by carrying a variety of pathogenic microorganisms. But this kind of creature seems to pop out on its own in hot weather, but it is rare to see it in winter, so how do flies survive the winter?

First, how do flies survive the winter

Flies generally have two ways to spend the winter. In winter, they lay their eggs in feces or in water. Compared with the cold outdoors, the faeces and underwater temperatures are higher to ensure that the eggs do not freeze to death. By the time of spring and summer, the flies began to breed again. Another way for flies to spend the winter is to fly into hotter rooms or caves to avoid the cold. When we clean the house in winter, we occasionally find some big flies that can't fly, most of which belong to this category.

In addition, the winter of flies is also related to the climate of the region. In the cold and temperate regions of the north, there are no very active flies in nature, and only in the indoor areas where artificial heating is used, there may be adult flies. In the subtropics of South China, when the average temperature is above 5 ℃, flies can continue to breed without dormancy.

Second, the harm of flies

Flies live and fall between garbage dumps, toilets, decomposing animal carcasses and purulent blood, sputum and vomit, and look for food. Its body surface and abdomen carry tens of thousands of bacteria, viruses and parasite eggs. The fly has the habit of eating, vomiting and pulling at the same time. Wherever it falls, the food and utensils will be contaminated by bacteria, viruses and eggs. When people eat contaminated food, intestinal infectious or parasitic diseases can occur.

Third, how to control indoor flies

1. The fly swatter is a sharp weapon to eliminate flies, and the fly can be killed with a fly swatter. But the fly-killing effect of this method has something to do with personal technology.

two。 Flies fly in from the outside, so the best way to kill flies is to prevent them. Reduce the time to open the door and install screens in the windows to prevent flies from flying in from the outside.

3. Insecticides are very lethal. Spray insecticides after closing the windows, and then open the windows for ventilation after a period of time, but pesticides are harmful to the human body and the environment, so multi-use is not recommended.

4. Put sticky fly paper. Sticky fly paper can stick the fly so that it can not move, after sticking to too many flies, you can change it. This method is only suitable for places where there are more flies and there is no need to strictly kill flies.

5. Take good care of indoor food and garbage to ensure a clean and tidy environment and reduce the conditions for the breeding of flies. In addition, indoor mosquito repellent products such as incense can also be used to reduce the entry of flies.

That's all we have to say about flies. When there are flies in the room, we must clean up the garbage at home in time to ensure that the room is clean, otherwise there will only be more and more flies and become a fly paradise.
