CATDOLL : CATDOLL: Where do cockroaches come from? Where do they usually hide?

1. The ancestors of cockroaches and other insects were originally arthropods such as sea scorpions and crabs on the seabed. They evolved from hail animals and were scavengers that preferred to hide during the day and come out at night, living in caves.

Second tank sail, where the cockroaches hide:

1. The kitchen at home is the place where cockroaches are most serious. Because there is abundant food in the kitchen, cockroaches generally like to look for food in the drawers of the cupboards, so cockroaches can usually be seen in the kitchen.

2. Since cabinets and drawers are closed and have many corners and gaps, cockroaches will regard cabinets and drawers as their "safe hiding places". It is not easy for people to find them hiding in cabinets and drawers, and even if they are found, they can easily find a place to hide.

3. The gaps in walls, floors, and various pipes are also places that cockroaches like to go, mainly because these places are hidden and cockroaches can hide well.

4. Dirty and humid environment provides good conditions for cockroaches to survive, so generally dirty and humid environment will easily breed cockroaches.

5. The bottom of household appliances such as refrigerators, televisions, microwave ovens and around compressors and radiators. Because there are sufficient heat sources in these places, especially in winter, cockroaches will hide in these places to "keep warm."

How to get rid of cockroaches:

1. Carefully check gutters, cracks in walls, floor partitions and windows, and take protective measures to prevent cockroaches from entering.

2. Keep the room clean. In a clean and dry environment, cockroaches will feel unwelcome.

3. Seal the food immediately after eating, clean up the garbage on the ground and in the garbage bag in time, and rinse the tableware with hot water first. Unclean tableware will attract the attention of cockroaches.

4. Use insecticide to kill cockroaches when no one is in the house.

Cockroaches are born from fucking cockroaches.

How to deal with cockroaches

Cockroaches have existed for more than 300 million years. Most of them grow in warm and humid environments and are common in offices and home rooms. Cockroaches are not only a nuisance to others, but the protein in their excrement is an important substance that causes allergic rhinitis and asthma, especially in children living in crowded rooms and cities.

How to get rid of cockroaches?

1. Carefully check gutters, cracks in walls, floor partitions and windows to prevent cockroaches from entering.

2. Keep the room dry. Cockroaches mostly live in humid environments, so be careful not to have any water leaks, especially in the kitchen.

3. Keep the room clean. In a clean and dry environment, cockroaches will feel unwelcome. :-). After eating, seal the food immediately, clean up the garbage on the ground and in the garbage bag immediately, and rinse the tableware with hot water. Dirty tableware will attract the attention of cockroaches. In addition, the stove and other places should also be cleaned regularly.

4. Use insecticide to kill cockroaches when no one is in the house.

Cockroaches are household pests that hide during the day and come out at night. During the day, cockroaches mostly hide in the corners of the kitchen and in the cracks of the cupboards, and move around at night to look for food.

Cockroaches eat almost everything, whether fragrant or smelly, hard or soft. Sometimes they will chew the glue inside the spine of a book, tearing the book apart; they will crawl into TVs and radios, biting the wire sheaths;

It can even bite the skin and fingers of infants. It also eats feces, sputum and the carcasses of small animals. It excretes while eating, making its body dirty, carrying germs, contaminating food and spreading various diseases, such as paratyphoid, dysentery, tuberculosis and acute hepatitis.

Cockroaches are very ancient insects, with a history of more than 320 million years. The fossils of cockroaches from the Carboniferous period look almost the same as today's cockroaches. After the Carboniferous period, many insects were eliminated one after another because they could not adapt to the changes in the environment, but cockroaches were able to survive tenaciously and became living fossils, which shows how strong their vitality is.

Now, cockroaches are found in almost every household, and have spread to big restaurants and hotels. Even ocean liners have become a "free world" for cockroaches, sometimes crawling on the decks and walls in broad daylight, oblivious to the people around.

It is not easy to swat cockroaches. At night, you tiptoe into the kitchen and suddenly turn on the light. You see the cockroaches panic and then they slip away into the dark corner in a flash.

Why are cockroaches so agile? This is closely related to the structure of their bodies. The cockroach's body is flat and has an oily sheen. The dorsal plate of its abdomen has the opening of a secretory gland, which secretes a foul-smelling liquid. On its triangular head, there are two small simple eyes and a pair of large compound eyes. The two upper jaws are fan-shaped, overlapping like scissors, with knobs between the teeth, which act like a vice when crushing hard objects. There are four antennae and many short hairs around its mouth. The antennae are its tools for collecting food, and the short hairs are its taste and smell organs, which have sensory organs on them.

The sensory nerves are used to find food or avoid poison bait. The nerve endings on the leg joints are very sensitive and can detect even the slightest vibration, so it is not surprising that cockroaches can detect the lightest footsteps. The cerci at the end of the tail are complex vibration receptors that can sense the direction of external stimuli, allowing them to escape quickly.

How to deal with cockroaches? People have created some methods to trap cockroaches.

Taking advantage of the cockroaches' habit of eating sweet food, use a small-diameter long-necked glass bottle, put some sweet food in the bottle, apply sesame oil on the bottle mouth, and the cockroaches will enter the bottle. Because the bottle wall is very slippery, it will be difficult for them to crawl out.

Taking advantage of the habit of cockroaches to drill into cracks, use a cardboard box with some gaps on the lid, apply glue inside the box, sprinkle some fresh bread crumbs, and let the cockroaches drill in to steal food and get stuck.

Taking advantage of the habit of cockroaches to scrape off dirt on their backs on hard objects, sprinkle some hard and sharp diatomaceous earth in the corners of the room. When the cockroaches go there to rub their bodies, too much of the wax on the surface will be rubbed off. As a result, a large amount of water in the cockroaches' bodies will be lost, and they will die of dehydration.

You can also kill the cockroach by interfering with its perception of external vibrations. For example, when you see a cockroach, immediately make a "hush" sound with your mouth, and then quickly slap it, which will make it easier to kill it.

Chemical drugs can also be used to deal with cockroaches. In places where cockroaches live and move, spray 5/1000 dichlorvos, or 3/10000 cypermethrin, boric acid powder, etc., or put a few cockroach tablets to kill cockroaches. There is a pyrethroid insecticide called "Mie Qiang Ling". It was tried in the kitchens of cargo ships, oil tankers and Yangtze River passenger ships of the Maritime Bureau. 300 milliliters of the liquid was sprayed in a 60 cubic meter cabin. The cockroaches immediately became excited and agitated, crawled out and died. Some fainted but not dead, and died after a day, and some stubborn ones did not survive more than five days.

Recently, scientists at the National Institute of Genetics in Japan discovered that toads (commonly known as toads) are the natural predators of cockroaches. Cockroaches once overran the small animal breeding room of the institute and people were helpless. Later, some toads were released into the breeding room, and soon the cockroaches disappeared. After dissection, it was found that most of the toads' stomachs were the remains of cockroaches.

A scientist in Kansas, USA, has developed a sex-smell trap to kill male cockroaches. It is mainly a kind of toxic sticky paper with smell. This smell is exactly the same as the smell of sex pheromone secreted by female cockroaches, which can lure male cockroaches to the sticky trap paper and poison them to death. As long as there is a little bit of this sex pheromone, male cockroaches within a range of about eight meters can jump into this trap within five seconds. Dutch scientists have also synthesized a similar sex pheromone. This indicates that the complete elimination of cockroaches is not far away. One day, people will generally use these ideal methods to make cockroaches that endanger human health "extinct".

Not long ago, foreign researchers developed a synthetic chemical that can release a special aroma to induce cockroaches to mate infertilely. If this continues, cockroaches will not be able to reproduce.

Usually in humid places, or

Many times cockroaches are brought in when buying vegetables. Small cockroaches are of southern species, while large cockroaches are of northern species. Once they enter the house, they are difficult to get rid of.

1. Cockroach caves like to live in warm, humid places with abundant food and many crevices.

Cockroaches usually hide in kitchens and bathrooms, in damp and dark environments with water, such as cupboards, drawers, gaps in sinks, under cabinets, and cracks in bathroom walls.

2. It likes darkness and is afraid of light. It hides during the day and comes out at night.

During the day they hide in dark, light-proof places, such as indoor furniture, wall cracks, caves, corners, and piles of debris.

3. In addition, cockroaches also like to get into computers and printers, causing communications and circuit short circuits, which are known as "computer viruses".
