Why do cockroaches appear in the house? Why do cockroaches appear in the house?

The home is damp, the home can be kept dry by opening windows for ventilation, the items are stored and folded neatly, the food is tightly sealed, and the probability of cockroaches is small.

1. What is the reason for the cockroaches in the room?

Cockroaches settle in a site with at least four basic conditions: a warm climate, a humid environment, an abundant food source, and a crevice-prone structure. Therefore, for what is the reason for the presence of cockroaches in the room, it is generally the characteristics of the room that meet these four requirements.

1. There are cockroaches in the neighbor's house, and the cockroaches enter the home directly 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.

Because there is food and cooking oil in the home, and the home is suitable for the survival and breeding of cockroaches.

In addition, the food, grain, rice, noodles, etc., which are usually purchased, are easy to bring in cockroach eggs, and cockroaches appear in the home after breeding.

1. Downstairs breeding invasion: Even if you live on the first floor and fail to eliminate cockroaches in time, when the cockroaches breed, they will slowly invade the whole building. 2. Fly in:

American cockroach, a more common indoor cockroach in our country, is more distributed in the south and also in the north. This is a cockroach that has a certain ability to fly. 3. Sewer:

Sewers are a place where cockroaches tend to stay, and the sewers at home are connected to the sewer network of the entire city. <

1. Breeding and invasion downstairs: Even if you live on the first floor, you can't eliminate cockroaches in time, and when the cockroaches breed more, the cockroaches will slowly invade the whole building.

4. Inadvertently brought into the house: In life, all kinds of things will be brought to the house, which may have cockroaches or cockroach egg sheaths, such as some cardboard boxes, old furniture, etc.

Cockroach extermination: 1. Insecticide: Kill cockroaches with insecticides is convenient and fast, in the case of no one in the house, spray insecticides in all corners, and then close the door and wait for a period of time, and when you come back, you can see the corpse of cockroaches on the ground, clean up with brooms and other tools, and it is best to disinfect the cleaning tools.

2. Cockroach sticker: Put an open cockroach sticker in a place where there are many cockroaches, and when you look at it the next day, you will see cockroaches stuck to the cockroach sticker.

3. Drug hunting: put some poisonous bait in the cockroach-infested area, and change the tomb to see it the next day, you can kill some cockroaches, if there are still cockroaches infested, continue to use this method to completely eliminate cockroaches.

1. Health reasons: cockroaches like to survive in a damp and messy environment, and the home hygiene is not cleaned in time, the environment is not clean, and there is also a humid environment. 2. Environmental structure reasons:

Cockroaches like to survive in cracked places, whether it is in the crack of the table or in the gap of the cabinet, it is easy for cockroaches to hide in the field. 3. Temperature reasons: cockroaches like to appear in warm climate periods, and this period is also the peak period for cockroach breeding.

1. Health reasons: cockroaches like to survive in a humid and messy environment, the home is not cleaned in time, the environment is not clean, and there is also a humid environment.

2. Environmental structure reasons: cockroaches like to survive in places with seams, and in places with more gaps, whether it is in the cracks of the table or in the cracks of the cabinets, it is easy to become a place for cockroaches to hide.

3. Temperature reasons: cockroaches like to appear in warm climate periods, this period is also the peak period of cockroach breeding, warm climate can make cockroaches easy to survive, so there are more cockroaches.

4. Abundant food: Abundant food, the essential for the survival of cockroaches is food, and the place where the food is stacked also provides a hotbed for the survival of cockroaches.

It is recommended to catch 8 to 12 o'clock in the evening when the cockroach is active, suddenly turn on the light to search, kill the adults and larvae, before the cockroach breeding season, hunt for several nights in a row, can greatly reduce the density of insects. Use hot soap or laundry detergent to pour cockroaches, eggs, and larvae that hide in various crevices. Carefully fill and smooth the gaps in stoves and cabinets where cockroaches are easy to hide.

For bamboo, wooden furniture, drawers, etc., which are inhabited by cockroaches, they can be watered with boiling water and scalded. Add a little sesame oil with No. 0 ink oil, apply it on kraft paper, sprinkle a little sugar fried noodles on the paper, put the paper on the stove, cupboard, etc., and put it in the evening and in the morning. Cockroaches are stuck when they are active.

It is generally valid for 10 days. HD and other special stickers are also sold.

Dear, I have carefully understood your question here, and after consulting the information and thinking, the standard answer to this question is: 1. Dampness at home: The place where the cockroaches and mantis appear at home must be quite quite.

Damp, for example, the doors and windows of the room are not often opened for ventilation, and the dampness cannot be self-sufficient.

However, cockroaches will appear in the wind and drying, and in such a humid environment, cockroaches will multiply from one or two at the beginning to hundreds in the later stage.

2. Dirty: Generally, the place where cockroaches like to live is next to the trash can, because it is rancid enough. If cockroaches suddenly appear in the home, then the hygiene of the home needs to be considered.

3. Heavy oil smoke: Cockroaches make people sound greasy.

I feel that when I was a child, there was a nursery rhyme that told the story of a little mouse going to the lampstand to steal oil, and cockroaches have nothing to do with it, and cockroaches like greasy.

Once the place, in the home, the stove, the kitchen is occupied by cockroaches, the consequences will be unimaginable.
