How can I get rid of all the cockroaches in my house?

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.

The commonly used effective methods now include placing poisonous baits to kill cockroaches, spraying insecticides, applying cockroach-killing chalk, spreading powder, and releasing insecticidal smoke, etc., which can be selected according to the actual situation. In addition to using chemical methods to kill pests, cockroaches can also be killed by physical methods such as sticky traps and trap bottles.

1. Root cause treatment measures

Wherever the environment is dirty and messy, cockroaches are rampant. Therefore, maintaining good hygiene and managing the environment are fundamental measures. To kill indoor cockroaches, we must first maintain good hygiene and eliminate cockroach habitats, widely carry out plugging holes and grouting seams and "eight inspections" activities, and remove cockroach habitats and egg sheaths and cockroach traces. Cockroach traces refer to insect corpses, remaining limbs, bodies, wings, molting, cockroach feces, empty egg sheaths, etc. "Eight inspections" refer to: one inspection of tables, two inspections of cabinets, three inspections of chairs, four inspections of mouths (sewer mouths), five inspections of pools (washing pools), six inspections of cases (food processing cutting boards), seven inspections of seams, and eight inspections of piles (coal piles, firewood piles, and miscellaneous piles). Cockroaches like to dig holes and hide in seams. Taking advantage of this living habit of pests, you can use putty, cement or silica gel to plug gaps and caves, leaving cockroaches with no place to hide. For kitchens with severely damaged interior wall structures and old furniture, to eliminate cockroaches, you must thoroughly repair the house and update the furniture.

2. Reasonable spraying to kill cockroaches

Cockroaches often live and hide in cracks and holes, so when using a sprayer to spray pesticides, be sure to spray cracks, holes, corners, and spray around them. This will have a good spraying effect and save pesticides. Cockroaches are reptiles, so when spraying pesticides to kill cockroaches, do not spray in the air, and do not spray all four walls.

3. Tips for placing poison bait to kill cockroaches

Placing poison bait is a common and simple method to kill cockroaches, but it should be used properly. The trick is "small amount, many points, and wide area", that is, more poison points in a room, less medicine at each point, and wider distribution area. In this way, cockroaches can eat poison bait when they crawl out of their habitats, and the killing effect is obvious. In order to prevent the poison bait from becoming ineffective due to moisture, it is advisable to place the poison erbium particles in the bottle cap. Use chalk containing insecticide to draw on the cockroach activity site. Around the cracks, holes and corners where cockroaches live and where they often move, use the medicine pen to draw circles or "wells" so that cockroaches will be poisoned to death when they enter and exit. The painted line should not be too thin, but should be a thick line of 2-3 cm.

4. When moving into a new home, don’t forget to kill cockroaches

In recent years, urban buildings have sprung up like mushrooms after rain, and a large number of residents have moved into new homes. Citizens are warned: when you move, please be sure to remove cockroaches and their egg cases hidden in old furniture, clothes, books, paper boxes, and wooden boxes, otherwise, cockroaches will soon be in your new house. Cockroaches cannot fly, and they rely on transportation and luggage, parcels, furniture and other goods to spread, causing them to spread between regions and even internationally.

1. Fresh cucumbers repel cockroaches. Put fresh cucumbers in the food cupboard and cockroaches will not approach the cupboard. Cut the fresh cucumbers after two or three days. The cucumber smell will continue to repel cockroaches.

2. Fresh peach leaves repel cockroaches. Place freshly picked peach leaves in places where cockroaches often appear. Cockroaches will stay away when they smell the scent of peach leaves.

3. Onions repel cockroaches. If you put a plate of sliced ​​onions in the room, cockroaches will immediately flee when they smell the smell, and it can also delay the smell of other foods in the room.

What to do if there are too many cockroaches at home

Place sticky paper in areas where cockroaches often appear. This method has little effect and is equivalent to "waiting for the rabbit to come to you".
