Why are there cockroaches in the building, why are there cockroaches in the room?

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.

Even in the kitchen, they generally like to live near stoves and sinks. Like the dark and afraid of light, day and night, this is also an important habit of cockroaches.

During the day, they are hidden in dark and dark places, such as indoor furniture, crevices in walls, caves and corners, and piles of debris. At night, especially after the lights are turned off and people go to sleep, they go out to do activities, or forage for food, or seek a mate. As a result, about 75% of the 24-hour day is spent at rest.

Cockroaches also have a habit of living in groups. It can often be found in a single habitat, always with a few or a few.

Ten or hundreds of them are clustered together, mainly due to the attraction of pheromones. Both adults and nymphs of cockroaches secrete an "aggregate pheromone" that is secreted by the rectal pad and excreted in the stool.

In places where cockroaches live, it is common to see brown fecal spots formed by their droppings, and the more feces there are, the more cockroaches gather. It can be seen that in the prevention and control of cockroaches, it is an important measure to do a good job in hygiene and remove cockroach traces.

Summary: Causes of cockroaches:

1. Cockroaches can crawl directly to the home through the sewer or other pipes connected to the outside world, and can also climb in directly through the doors and windows of the home.

2. Cockroaches can also carry cockroaches into the home through carry-on bags, shopping bags, suitcases, item packing boxes, etc.

3. The method of preventing cockroaches from entering the home: with external wires and pipes, air conditioning pipes, exhaust smoke outlets, etc., can be blocked, do not leave holes and gaps, and the sewer can be blocked with net plugs to prevent cockroaches from entering the home from these places.

4. The windows of the home are equipped with screens, and the screens are usually closed to prevent cockroaches from flying directly into the home from the outside world.

5. Whether the home is clean or dirty, there will be cockroaches, although there are cockroaches at home and whether they are clean or not is not directly related, but we still need to maintain the hygiene of the home, a clean and tidy environment can allow us to better get rid of cockroaches.

Answer: Cockroaches enter the home through the following ways: 1. There are cockroaches in the neighbor's house, and the cockroaches directly enter the home from the outside world through sewers, air conditioning pipes, doors and windows, etc. 2. Carry cockroaches or cockroach eggs through shopping bags, packing boxes, suitcases, etc., and bring cockroaches into your home.

This is also the most likely, usually we will bring cockroaches to the house if we are not careful. Precautions: 1. To eliminate cockroaches, we must first ensure environmental hygiene, clean them in time, including toilets and sewers, and clean up garbage in time.

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. It should be carefully inspected, even the old computer case. It is best for the whole building to act in unison, so that the cockroaches have nowhere to hide.

2. Keep the residence dry and clean: demarcate strict eating areas, except for restaurants and kitchens, food is strictly prohibited. Pay attention to the cleanliness of the kitchen and bathroom, and strictly prohibit stagnant water.

3. Store food properly and clean up food residues thoroughly after feeding pets.

(1) Cockroaches mainly live in the kitchen, in all the gaps between the cabinet frame and the wall, the cracks in the wall, and the kitchen drain are its habitat, and they can be sprayed with insecticides, plugged the gaps, and scalded with boiling water.

2) If there are too many cockroaches in the decoration room, it is best to close the doors and windows tightly, burn 10 of the drips with an alcohol lamp, and burn it for an hour or two to smoke a large number of cockroaches to death. But it should be remembered that cockroaches are extremely vigorous, and sometimes they are just unconscious, and they are not really dead. So you can't throw it away as garbage, it's better to scald it with boiling water.

Otherwise, many cockroaches will wake up after ten minutes, which is equivalent to "letting the tiger return to the mountain".

3) Place the sticky paper in a place where cockroaches are frequented. This method has little effect, and it is equivalent to "waiting for the rabbit".

4) Cockroaches should not be beaten by fly swatters, and should not be trampled to death with their feet. It is best to use cockroach paper to see one sticky one, which is very accurate and effective. Stepping on it with your feet will cause a large number of germs and viruses in the cockroach's body to spread everywhere.

The eggs of cockroaches are protected by thick pods that have hard walls and a high backbone and breathing tube, preventing insecticides from penetrating. The most effective solution is to use professional equipment, use knowledge of pest habits, and retreat its larvae during their survival period to sanitize.

1. Passive invasion: Mainly carried into the home through carry-on bags, shopping bags, suitcases, item packing boxes, etc.

2. Active intrusion: mainly through doors, windows, wall gaps, water and electricity pipelines, sewers, etc., sneaking into the home from the outdoors or the neighbor's house.

Generally, the first possibility is relatively large, and the second possibility will be relatively small, because cockroaches migrate passively in many cases, and rarely actively migrate.

Clause.

1. Cockroaches crawl into the house through holes and gaps.

Most people's cockroaches in their homes come this way.

You may say that now they are all reinforced concrete buildings, how can there be holes and gaps?

But don't forget, install air conditioners, water heaters, exhaust fans, and exhaust fans, all of which have reserved holes.

You may be able to seal these holes, but if they are not completely sealed and there are gaps, cockroaches can still crawl into the house from the outside.

Clause. Second, cockroaches fly directly into the house through the window.

If you don't have screens on your windows, cockroaches can fly straight into your home when you open them at night.

Or maybe fly straight to your balcony and hide in the washing machine, or hide in your cool clothes and wait for you to collect your clothes and go back to your room.

Or the cockroaches hide on the balcony and then wait for an opportunity to enter the house.

It usually runs out of the sewer.

There are a lot of cockroaches in summer, they like to hide in sewers, garbage cans, various cabinet corners, refrigerator corners, so hate cockroaches, now cockroaches are very capable, and they can actually fly.
