How long do flies stay to produce bacteria, and dead flies have bacteria or not

Your problem should be divided into two parts: 1. As long as the fly stays, bacteria will be retained, and the longer the stay, the more bacteria will remain. 2. It is best to wash the bowl or cup where the flies have stayed and then use it, if it is inconvenient, or you don't see it, it is generally no problem to wash it, because most people have immunity (as the saying goes:

The bacteria carried by flies are not necessarily pathogenic bacteria, or the number of pathogenic bacteria may not necessarily reach the amount of pathogenic bacteria. Bacteria exist very widely in the environment, such as our hands, clothes, and our living environment almost everywhere, but the proportion of pathogenic bacteria in bacteria is very small, so there is no need to be too afraid of bacteria, as long as you pay proper attention to hygiene, it is not necessary.

It's usually stopped... In fact, there are many bacteria in the air, but they generally cannot break through the body's immune system, so the average person will not get sick all of a sudden because they live in a non-sterile environment. So in fact, don't talk about whether cooking can kill all the bacteria, just after the pot, because the air, hands, dishes and chopsticks, the bacteria have been constantly stained...

1. Bacteria are everywhere.

2. There are many bacteria on flies. This is because flies like to stay on spoiled food, and spoilage plants are caused by microbial growth.

3. Flies like to lay eggs on food. So, the food that has been eaten by a lot of flies should be poured out. If it's just flying, let's wash it.

Studies have found that flies can carry more than 60 kinds of bacteria, and a fly can carry more than 1 million bacteria on its body surface, and the maximum can carry about 500 million. Flies carry and transmit many pathogens, which can transmit dysentery, typhoid, cholera, poliomyelitis, tuberculosis, trachoma, hepatitis, parasitic diseases and other diseases. Common flies in people's lives include houseflies, toilet flies, mercerized green flies, big-headed goldflies, black-tailed hemp flies, etc.

The life of a fly can be divided into four stages, that is, from the adult fly mating and laying eggs, through the egg-> larva (maggot) - > pupa - > the process of adult fly, this process only takes about 10 days, and can be shortened when the temperature is high. Flies can lay eggs for life when mated once, and a fly can reproduce thousands of flies in its lifetime. Spring is the peak of the first generation of adult flies, and the elimination of one fly in the spring is equivalent to the elimination of tens of thousands of flies in the summer.

Flies breed and fly among garbage heaps, toilets, rotting animal carcasses, pus, blood, sputum and vomit and feed on them. It carries tens of thousands of bacteria, viruses and parasite eggs on its body and abdomen. Flies have the habit of eating, spitting and pulling, and he flies down to **, ** food and utensils will be contaminated by bacteria, viruses, and insect eggs, and when people eat contaminated food or use contaminated utensils, intestinal infectious diseases or parasitic diseases can occur.

Dear, here's the relevant information: flies are familiar and disgusted insects, they have a wide variety of species, and the main harm to humans is to spread diseases. After research, it was found that flies can carry more than 60 kinds of bacteria, and a fly can be stained with more than one million bacteria on its body surface, and the maximum can carry about 500 million.

Swatting dead flies can cause more than a million bacteria.

Analysis: Many of the bacteria that flies are infected with are mainly hidden in the digestive tract. Most of these bacteria are harmful to humans, such as typhoid bacillus, bacillus dysentery and other pathogens, but they are not harmful to the flies themselves.

Because some disease-causing microorganisms can survive quietly in the body of the vector insect or reproduce, but it will not cause harm to the insect itself. This is due to the adaptation between the pathogenic microorganism and the vector insect in the long-term evolutionary process. According to experiments, many bacteria that are harmful to humans only live in the digestive tract of flies for five or six days, some of them die, and some of them are excreted with feces.

So, although flies stay in dirty places and carry a lot of bacteria in their bodies, these bacteria do not make it sick.

Hello children, the fly has bacteria on its body or feet, even if it dies, the bacteria will still be there, and it should be thrown into the trash after it is killed.

Hope it helps.

Bacteria are everywhere, even on the corpses of flies

The flies are dead, and the dead flies still have bacteria on them. Bacteria are everywhere, and bacteria are present in insects and various animals after death.

Answer: If the crushed flies are not treated in time, they will breed bacteria, cause environmental pollution, and affect health. The solution is good and the steps are as follows:

1.First of all, it is necessary to dispose of the crushed flies in time, which can be wiped with a damp rag or vacuumed away to avoid the growth of bacteria. 2.

Secondly, it is necessary to clean the environment regularly, keep the indoor air circulating, and increase the indoor humidity to prevent the breeding of flies. 3.Again, take precautions, and if you find flies indoors, you can use insecticides or fly traps to prevent flies from breeding.

4.Finally, pay attention to food hygiene and maintain indoor hygiene to avoid fly breeding. The above are the methods and practical steps to solve the problem of crushing dead flies to breed bacteria, I hope it can help you.

30 35 is particularly active.

Suitable temperature: 30 35 is especially active, 35 40 stops due to overheating. 45 47 hours to death.

It can only crawl at 4 7 o'clock, fly at 10 15 o'clock, and feed, mate, and lay eggs at 20 or more.

Physiological characteristics: flies have the physiological characteristics of laying eggs for life after a mating, a female fly can lay eggs 5-6 times in a lifetime, and the number of eggs laid each time is about 100-150, up to about 300 grains. It can breed 10-12 generations in a year.

Flies are insects that are frequently active during the day and have obvious phototaxis. At night, it is stationary. Activity, habitat, depending on the species, season, temperature and region.

In some seasons, rot flies, summer flies, and city flies can also invade homes. Big-headed golden flies, mercerized green flies, lily flies, volcanic flies, and hemp howling flies are mainly active and inhabit outdoors.

At minus 5, death occurs in 3-5 days.

The activity of flies is greatly affected by temperature. At minus 5, death occurs in 3-5 days. At temperatures below 10 degrees, most flies lose their mobility.

It can only crawl when it is 4 or 7. At 10 15 you can fly and fly. 20 or more to feed, mate, and lay eggs.

30 35 is especially active. 35 40 Stopped due to the repossession of the repossession. 45 47 hours to death.

The lifespan of most flies is very short, the common house flies, in the middle of summer, can only live for about 1-2 months, but in the spring and autumn, their lifespan is longer, can live for 3-4 months.

Flies are insects belonging to temperate to tropical regions, adapted to a wide range of temperatures, and can generally survive and reproduce in an environment of 20 to 30. However, the specific lifespan of flies is related to various factors such as environmental factors, species, and individual differences, so it is not possible to simply "how many degrees" will die. In addition to this sales, the death of flies is also related to factors such as whether they are full and whether they are in danger.

In general, flies have a shorter lifespan, only about 15-30 days.
