Why do flies keep flying in the house and flies flying around the room

A: It may be because you've created an overly warm atmosphere – flies like to live around 30 degrees, especially when the temperature outside the room is very low. If there are still flies willing to share your ups and downs in the summer, check the trash can......Looking at it from another angle, we can't be sure whether the flies flying in from the outside were unintentional or intentional. However, when the fly was about to go out again, the six-sided predicament made it difficult for it, accustomed to infinite space, to find the right way out - just look at the warriors who were frantically pounced in front of the glass windows.

B. Let us make two assumptions: first, that the movement of flies is largely random; 2. The average density of flies outdoors is greater than that of indoors. If we agree with these two assumptions, we can conclude the following:

When the window is open, the mathematical expectation of the number of flies flying into the room from the outside through this window is known from the first hypothesis.

In the same way that the expected number of flies flying from the inside out is proportional to the density of indoor flies, and the proportional coefficient of the two is approximately equal. Based on the second hypothesis, we know the expected value of flies flying from the outside in.

It is greater than the expectation value of flies flying from the inside out, which causes the expectation of fly flow from the outside in, that is, the flies fly in and are easy to fly out. Alternatively, flies can be seen as ideal gases.

molecules (i.e., regardless of their interactions), can be seen as a bottle of less dense gas indoors and a denser gas outdoors. When the bottle is connected to the outside world, the diffusion density of the gases inside and outside the bottle tends to be equal, and the second hypothesis tells us that such a change will increase the density of flies in the room. The phenomenon is that flies are easy to fly indoors but not out.

C can be used with "Murphy's theorem."

to explain: if something bad is likely to happen, then it will happen. Let's say we have a fly, and then there are two windows, then each window has a 50% chance of getting into a fly.

However, for a particular window, as long as flies come in this window, it is a 100% chance for the people in the house, because the people themselves are not impressed by the good things, but the bad things are still freshly remembered, and in the long run, everyone will feel that the flies are easy to enter the house. D: Usually flies will fly into the room against the weak air currents at the entrance when they smell the smell they like, and they are generally reluctant to leave a place where they can provide them with tasty (and even if it tastes okay) food, unless food is scarce or alarming and they are forced to fly out to find a new location. It doesn't really matter why and how flies get indoors, the important one is that one loses a sense of security.

There are several reasons why flies keep flying into the house:

1.It may be that the plastic bags for the garbage are relatively thin, and some insects or their larvae can bite out of the holes and then get out.

2.It may be that there is not necessarily only one type of insect in the garbage, and cockroaches can bite through plastic bags. In addition, external cockroaches and other insects may bite through plastic bags to find food.

3.It may be that even if the water seal in the sewer is good and the product is fully qualified, it cannot completely rule out the possibility of mosquitoes and flies entering the room through this channel.

4.It may be that indoor hygiene is not done well, especially in the kitchen and bathroom, where there is generally a lot of domestic garbage, which is a breeding place for flies and insects.

To prevent flies from entering the room, there are a few precautions that can be taken. For example, cleaning the room regularly, disposing of garbage properly, sealing the room with a screen, etc.

1. The respiratory system of flies is very small and fragile, and it needs continuous clean air**, which can burn incense to eliminate flies, and the smoke and fragrance emitted by incense sticks will numb flies and gradually die.

2. In wet places, places with water and soil should be inspected, cleaned and sprayed with pesticides.

3. Using a fly swatter, the current inside will directly electrocute the fly, because the fly can feel the change of airflow, and the design of the mesh will greatly improve the efficiency.

4. Put the sticky fly paper in the place where flies often appear, the smell of sticky fly paper will attract flies to come, and then stick the flies on it.

Kiss! Hello, happy to answer your <>

Dear, big flies will fly to the house because the kitchen scraps, garbage is not cleaned up in time, or the trash can is not covered, there may be the following reasons for the appearance of big flies at home:1. Improper storage of food:

Food scraps can attract many insects, especially flies. If you don't store your food properly or clean up your food in a timely manner, then these flying insects will be attracted to your home. 2。

Keeping pets: Owning pets can produce garbage and droppings, which are the main foods for flies**. If your pet feces are not cleaned up in time or your pet feed is not stored in a closed container, then they may attract flies to breed at home.

3。Water problems: Flies need water to survive, and your home may have a leak or standing water in a nearby area, and it can also be a place for flies to lay eggs and breed.

4。Indoor temperature: Warm indoor air temperatures are also an important factor in the breeding of flies, especially during the summer and wet seasons.

Also, clean the room from dust and clutter at all times to prevent flies and other insects from entering and breeding.

5.Practical ways to cope.

If flies have already entered your room, there are a few things you can do to keep them out. Among them, the more commonly used is to use fly swatters, traps and other items to drive away flies. In addition, you can also hang fly paper or spray mosquito repellent to avoid flies approaching.

6.Get to the root cause and solve the problem.

If you notice that flies are flying into your room more frequently, it could mean that there is a serious hygiene problem or that doors and windows are poorly sealed. Therefore, you need to find the root cause and solve the problem in time. Paying attention to personal hygiene, cleaning the room regularly, and improving the sealing of doors and windows are all ways to help reduce the entry of flies into the room.

7.It is better to prevent it before it happens.

Flies are one of the main spreaders of diseases and health threats that are easy to traverse and difficult to control. While keeping the environment clean, we should also pay attention to finding new prevention techniques, such as using better measures in food storage and handling. This is an important aspect of ensuring the safety and health of our living environment.

8.Conclusion.

Flies entering a room can be a sign of many hygiene and life problems. We must be aware of this problem and take steps to solve it. Regular cleaning and disinfection and taking steps to keep the environment clean and hygienic conditions ideal can help reduce the chances of flies entering the room.

It may be flea flies, and the adult will be attracted into the room by the smell of rotting garbage, and the larvae are rotten-eating and will breed in garbage cans that have not been emptied for a long time. You can take out the garbage frequently, preferably not overnight, to effectively control fleas and flies.

There are ways to get rid of flea flies:

1.Mothballs deworming. You can put three mothballs in the bucket, which can not only deodorize, but also keep the insects away.

2.Mountain bark pesticide. Boil the mountain skin in a pot, and when the water is brown, pour the water into a watering can, then use a watering can bucket, and finally wash the bucket with clean water. The mountain skin water can deodorize and prevent insects, and the bucket washed with mountain skin water can ensure that there is no peculiar smell within three days.

3.Bucket with lid. Buy a bucket with a lid, remember, it must be with a lid to be useful.

4.Homemade insecticide. Prepare the materials:

Sugar, white vinegar, detergent, slim glass. Put granulated sugar in the glass first. Then pour in the white vinegar, do not stir or shake, do not spill the vinegar or spill it on the glass wall.

Finally pour in the detergent so that the flies will sink. After leaving it in the kitchen overnight, the flies will be destroyed.

The hazards of flea flies.

The eggs, larvae, and pupae of the great flea fly can enter the bacterial bed with the culture material, and the adults can fly directly into the eggs of the giant flea fly. The adult flea fly does not directly harm Ganoderma lucidum, but can carry various pathogenic bacteria, nematodes and mites into and out of the Zhizhi room, and is the vector of Ganoderma lucidum diseases and pests. In the early stage, the larvae of the giant flea fly mainly feed on the mycelium of Ganoderma lucidum and the tender tissues on the surface of the young mushroom, and in the later stage, they expand to the fruiting body and eat its sap.

When the larvae seriously harm the bacterial bed, the mycelium of Ganoderma lucidum will shrink, the color will turn from white to brown and finally black, and the culture material will be bored into chaff, resulting in the bacterial bed not producing Zhizhi or a small amount of Zhizhi. After the fruiting body is damaged, pores appear in the tissue, the appearance turns brown, the body is hollowed and soft rot, or the fruiting body dies.

There are ways to prevent flies from flying around the room:

1. Larvicide:

Highly effective larvicides are mainly used in the larval stage of fly development, and the effect can be seen after 2 weeks of application, and these insecticides can be sprayed directly on the manure of livestock and poultry houses or sprayed on the ground after the manure has been removed.

2. Biological prevention and control

The biological control of flies is to cultivate the natural enemies of flies in feces, including beetles, mites and wasps, etc., and under natural circumstances, there are few natural enemies of flies in feces. Drying livestock and poultry manure is conducive to the growth of natural enemies of flies.

Fly hazards:

Flies can transmit 50 kinds of diseases, among which important diseases that have an impact on livestock and poultry breeding such as avian influenza, Newcastle disease, foot-and-mouth disease, swine fever, avian multocidal pasteurellosis, avian colibacillosis, coccidiosis, etc., flies can accelerate the spread of epidemic diseases in disease outbreaks. A large number of flies in the house can cause irritability and contaminate the eggshells.

The activity of maggots in the feces can lead to an increase in the ammonia content in the poultry house, affect the production performance of the chickens, and can also lead to mental restlessness of the livestock, and the body of the herd rubs against each other, bites each other, etc., resulting in damage to the appearance and reducing the grade of meat.

Flies are compound eyes, and their eyesight is a hundred times stronger than that of humans. But flies are insects, and it is impossible to know how to think and analyze whether they can go out like people. It will only follow instinct, go on a rampage, keep flying, and the straight happens to fly out.

Because flies don't have memory. He can only remember briefly. He couldn't find his way in. When you come in, you instinctively follow the smell and come in, and of course you can come in through the hole. But it's very difficult to get out. The house was a big labyrinth to him.
