Why do cockroaches die out naturally in autumn?

In autumn, cockroaches don't die out naturally.

Cockroaches are the most abundant between July and September every year, and the most suitable temperature for cockroaches to survive is 24 32 degrees, that is, in July and September every year, during this time, cockroaches breed most vigorously, and it is also the main season for cockroach extermination.

The suitable temperature for cockroach activity is 20 30. When it is below 15, most of them are immobile or fretting; Euphoria is high above 37 and death is over 50. The seasonal growth and decline of cockroaches is greatly affected by temperature, and the same insect species can show different seasonal distribution in different regions.

In most parts of our country, cockroaches usually start to appear in April, reach a peak in July and September, and gradually decrease after October until they disappear. When the temperature is below 12, they overwinter as adults, nymphs or eggs in dark, windless shelters. Wet, dirty, with food.

These factors inevitably lead to cockroaches.

Moreover, the activity and reproduction of cockroaches, like other insects, are affected by temperature. Under normal circumstances, the seasonal growth and decline of cockroaches is a change in the number of populations or communities that manifest themselves in response to changes in temperature.

At the same time, cockroaches like to gather in warm, humid, food-rich and crevice-ridden places, so after central heating, cockroaches will "move closer" to the heating equipment. During the period before heating, cockroaches tend to gather behind appliances that can dissipate heat, such as refrigerators, microwave ovens, ovens, and water heaters. In addition, the kitchen is also a place with a high density of cockroaches because of the abundance of food.

Even when there is no food in the living environment, cockroaches can survive by nibbling on confetti.

Moreover, there will be cockroaches in winter, cockroaches are very strong in survivability, and they appear all year round, even in the cold winter, their crawling speed is very slow, but there are still cockroaches that will come out to feed, mostly at night when there is no light.

The important thing is that cockroaches do not need to hibernate, the winter is cold, many insects and even animals need to spend the winter by hibernating, but cockroaches are an exception, cockroaches will only hide in dark and warm corners in winter, but it does not mean that they are hibernating, and they will also come out to forage at night, especially cockroaches in air-conditioned rooms, which are no different from summer and autumn.

Relevant experts said that the vitality of cockroaches is particularly tenacious, and its life tenacity is far beyond people's imagination, so there is no such thing as "Xiaoqiang" will die naturally in autumn and winter. Even if there is no food in the living environment, even if you nibble on a little scrap of paper, the cockroach can still maintain life. Even in a harsh environment such as dark and foul-smelling sewers, the "little powerhouses" can survive.

In addition, they are small in size, and even narrow crevices can be drilled into, so it is extremely difficult to kill cockroaches.

However, industry experts suggest that although cockroaches will not die naturally in autumn and winter, but in autumn and winter, especially before and after heating, it is the best time to exterminate cockroaches.

Cockroaches are characterized by their preference for hiding in warm, humid places with abundant food and many crevices. Therefore, during the period before heating, cockroaches tend to gather behind refrigerators, microwave ovens, ovens, water heaters and other appliances that can dissipate heat, and after heating, they will move closer to heating equipment. In addition, the kitchen at home is also a place with a high concentration of cockroaches because of the storage of more food and the humid environment.

Experts say that if there are cracks in the house, you have to use cement or glass glue as soon as possible.

Wipe to death, don't leave a "way" for cockroaches. If cockroaches are found in the house, you can use the method of "one spray, two smokes and three booby-traps".

If you use the "spray" method, it is best to change the spray frequently and try to use different brands of insecticides. "Smoke" means that the doors and windows are closed first, a layer of insecticidal water is sprinkled on the floor, and then smoked to "force" all the cockroaches to go out, once they touch the insecticidal water, the cockroaches will die quickly. Finally, there is "booby-trapping", which can generally be placed in the gaps of worn tiles in the kitchen and toilet, the bottom of the sofa, the bottom of the computer, and the back of the bed, and place cockroach bait.

If you find that there are a large number of cockroaches in your home and it is difficult to eliminate them, you can seek help from a professional team.

Experts remind that cockroaches are not only annoying, but also carry a variety of bacteria on their bodies, which can easily contaminate food and daily necessities.

Killing must be carried out as early as possible. Exterminating cockroaches is a long-term project, and there is no need to wait for the best time, and it is best to find and kill them at any time.

In autumn, the weather begins to get colder, and the conditions for the cockroaches to survive become unfavorable. Cockroaches usually survive in warm environments, so it can be difficult for them to find a suitable place to survive when the temperature drops. In addition, autumn is also the breeding season for cockroaches, so they will also be busy breeding.

In the process, they can die for various reasons, such as being eaten by animals or dying because of the weather. Therefore, in the fall, cockroaches are likely to die out naturally.

Because cockroaches eat almost everything, and cockroaches reproduce very quickly.

Cockroaches prefer to choose warm, moist, abundant food and crevices to live, which are the 4 basic conditions they need to breed. All buildings where people live and live generally have these conditions, so cockroaches have become a sanitary pest that infests thousands of households. Warmth and love tide is an important habit of cockroaches.

It is not difficult to find that whether it is in a restaurant, a home, a train or a ship, the kitchen is always the most invasive.

Prevention and control measures. 1. Always keep hidden places clean. To find the source of the insects, you can suddenly turn on the lights at night when the cockroaches are active, observe where the cockroaches are, and where they are going, find their hiding places and then eliminate them.

2. For sheltered places, Keswei can be used in places where cockroaches often come and go.

3. Apply paper tendons and lime (500 grams of paper tendons plus 50 kg of lime, and then add water to mix) paint to all the gaps, and plug the gaps.

4. If there are too many cockroaches in the warehouse, workshop or indoors, and the harm is serious, it can be eliminated by sulfur or aluminum phosphide fumigation.

Cockroaches do not go extinct because cockroaches are extremely reproductiveEvery 7-10 days, a mature female cockroach can produce an egg sheath containing 14-40 eggs, which are colloidal and hatch between 20 and 37.

The higher the temperature, the shorter the incubation time, at a constant temperature of 30, it only takes 20-30 days, and the longer can exceed three months. The eggs of cockroaches are protected by a thick egg sheath, which cannot be penetrated by ordinary insecticides, and can only be killed again after they hatch. This is also one of the reasons why cockroaches have been extinguished for a long time.

Methods of cockroach control at home

1. To eliminate cockroaches, we must first ensure environmental hygiene. Clean in a timely manner, including toilets and sewers, and remove garbage in a timely manner. Do not leave sanitary dead corners in the home, do not place food in the open air in the kitchen, do not leave stagnant water in the home, and plug the cracks and holes in time, so as to prevent cockroach breeding.

2. Prevent cockroaches from coming in. The pipeline extending in all directions is a rapid transit system for cockroaches to travel unimpeded. At night, cockroaches in gutters crawl indoors in swarms along drains, through drainage holes, walls, cracks in doors and windows.

Why are the cockroaches that everyone shouts about not extinct yet? Scientist: Nature needs it.

Don't choose any cockroach medicine. There is no cockroach medicine that can ** cockroaches, and after you use the medicine, cockroaches will gradually become resistant and more difficult to get rid of. The best way to do this is to keep it dry and ventilated.

Cockroaches don't disappear in winter, they hide. In winter, the temperature drops, and when the temperature drops to a certain level, cockroaches will feel cold and find a warm place to hide. Most of the warm places in winter are relatively hidden, and generally we rarely go to check them, and cockroaches hide in these places and do not come out to move.

So, in the winter, we will feel that the cockroaches are gone, and there are no cockroaches.

In fact, the cockroaches are gone in winter, and it is relatively simple to find them, just check the warm places in your home. For example: the fan heat vent on the back of the refrigerator, the heat vent of the induction cooker, the router fan heat vent, etc.

Generally, electrical appliances that have been energized for a long time will generate heat, and this heat will form a heat source, and cockroaches like to hide in these places in winter.

Ways to get rid of cockroaches.

1. Use sticky cockroach paper to stick one by one, which is very accurate and effective. Don't step on it, if you step on it, it will release a large number of germs in the cockroach's body.

2. Use a sugar water bottle to catch cockroaches, take 1 to 2 canned food bottles, put 3 tablespoons of sugar water, and add half a bowl of boiling water to rinse it, as a bait. Put the bottle in the place where the cockroaches are active, once the cockroaches smell the sweetness, they will crawl into the "trap" of the canned bottle, which is simple and easy.

3. Hot soapy water to kill cockroaches, put the soap in 4 liters of hot water, and then spray it directly on the cockroach after it is dissolved, which can effectively kill cockroaches.

It is because the reproduction rate of cockroaches is relatively fast, and sometimes it is related to the high temperature of the environment, and it is also related to some impurities falling on the ground.

It is also because the cockroach's reproductive ability is very strong, although a batch of them have been killed, but there are other cockroaches still alive, so after a period of time, there are again.

Because cockroaches reproduce very quickly, and cockroaches are not completely removed, they will always appear.

Because the family has not paid attention to hygiene, even after the cockroaches are eliminated, they will still appear after a while.

Because the cockroach has a very strong survivability, its vitality is very tenacious, it is not easy to die, and it is difficult to completely eliminate it.

It shows that the inside of the house is very humid, because the reproductive ability of cockroaches is particularly strong, and it is impossible to eliminate them.

Although these people have eliminated cockroaches, the bacteria in the home are still breeding. It will attract a lot of cockroaches.

Summary: No.

Below -3 degrees, it will take 17 consecutive hours for cockroaches to freeze to death and disappear. Water above 70 degrees can kill. Cockroaches, generally referred to as belonging to the "order of cockroaches."

Summary. Hello dear! 1. Cockroaches enter the home through sewers or other places that are connected to the outside world, and may also be carried into the home through shopping bags or suitcases.

2. The cockroaches bred by the previous cockroach egg sheath, of course, if it is a small cockroach, it may be reproduced, and the big cockroach should be the former situation, the cockroach egg sheath is a hard shell to protect the eggs inside, and at present, there is no drug that can kill it, so after the adult cockroaches are extinct when the drug is used, these cockroach egg sheaths still exist, and they will be bred after a period of time, so that cockroaches will appear in the home again. Another feature of killing cockroach bait is that it can kill cockroaches for a long time, so even if the cockroaches at home are extinct, there is no need to worry about the reappearance of cockroaches, as long as there is medicine, cockroaches can still be killed after eating, so that they will not reproduce in large numbers.

After the cockroaches are eliminated, why do they reappear every once in a while?
