Cockroach is a very ancient insect, with a history of more than 320 million years. The appearance of cockroach fossils from the Carboniferous era is 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. However, the cockroach survived tenaciously and became a living fossil, which shows how strong its vitality is.

Nowadays, the footprints of cockroaches can be found in almost every household, and have expanded to large hotels and hotels. Even ocean-going ships have become a "free world" for cockroaches. Sometimes, during the day, they will crawl on the decks and walls as if no one is around.

Why do cockroaches move so quickly? This is closely related to the structure of its body. The cockroach's body is flat with an oily sheen, and there are openings for secretory glands on the back of the abdomen, and the secreted liquid has a foul smell. On its triangular head, there are two small single eyes and a pair of large compound eyes. The two upper jaws are fan-shaped and overlap like scissors. There are knobs between the teeth, which look like a vise when crushing hard objects. There are four tentacles and many short hairs around the mouth. The tentacles are its tools for collecting food, and the short hairs are the taste and smell organs with sensory nerves on them, which are used to find food or avoid poisonous baits. The nerve endings in the leg joints are very sensitive and can detect the slightest vibration, so it is not surprising that cockroaches can detect the lightest footsteps. The whiskers at the end of the tail are complex vibration receptors that can sense the direction from which external stimuli are coming, allowing it to escape quickly.

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

Using the cockroach's habit of eating sweet food, use a small-diameter long-necked glass bottle, put some sweet food in the bottle, and apply sesame oil on the bottle mouth. The cockroach will enter the bottle because the bottle wall is very slippery. Climbing out is difficult.

Using the habit of cockroaches to get into gaps, use a paper box with some gaps on the lid. Apply glue inside the box and sprinkle some fresh bread crumbs so that the cockroaches can get in and eat and get stuck. .

Use the habit of cockroaches to scrape dirt off their backs on hard objects, and sprinkle some hard and sharp-edged diatomaceous earth in the corners of the room. When the cockroaches go there to rub their bodies, the surface layer will The wax oil will be wiped off too much. As a result, the cockroach will lose a lot of water and die of dehydration.

You can also use methods to interfere with the cockroach's perception of external vibrations to extinguish it. For example, as soon as you see a cockroach, immediately make a "shhh" sound with your mouth, and then quickly slap it, it will be easier to kill it. .

Chemical drugs can also be used to deal with cockroaches. In places where cockroaches live and move, spray 5 parts per thousand dichlorvos, or 3 parts per 10000 deltamethrin, boric acid powder, etc., or put a few cockroach tablets A tablet can kill cockroaches. There is a pyrethroid insecticide called "Cockroach Killer", which has been tried in the galleys of freighters, oil tankers and Yangtze River passenger ships of the Maritime Bureau. When 300 ml of pesticide solution was sprayed in a 60-cubic-meter cabin, the cockroaches immediately became excited and commotion. , crawled out and died. Some of those who fainted but survived died after a day, and some stubborn ones did not survive more than five days.

Recently, scientists from Japan’s National Institute of Genetics discovered that toads (commonly known as toads) are the natural ancestor of cockroaches. The small animal breeding room of this institute was once overrun with cockroaches, and people were helpless. Later, some toads were put in the breeding room, and soon the cockroaches disappeared.

After an autopsy, it was found that the toad's stomach was mostly filled with remains of cockroaches.

A scientist in Kansas, USA, has developed a sexual scent capture device to trap and kill male cockroaches. It is mainly a toxic sticky paper with a scent. This smell is exactly the same as the smell of sexual pheromones secreted by female cockroaches, which can lure male cockroaches to the sticky capture paper and kill them. As long as there is a little bit of this sexual pheromone, male cockroaches within a range of about eight meters can jump into this trap device within five seconds. Dutch scientists also synthesized a similar sex pheromone. This indicates that the complete eradication of cockroaches is not far away. One day. People generally use these ideal methods to eliminate cockroaches that endanger human health.

Not long ago, foreign researchers also developed a synthetic chemical that can release a special aroma to induce cockroaches to engage in sterile mating. If this continues, cockroaches will no longer be able to continue their family lineage.

★Second Strategy★

The commonly used effective methods now include putting poisonous bait to kill cockroaches, spraying insecticides, applying cockroach-killing chalk, spreading pesticide powder, spraying insecticidal smoke, etc., Choose to use according to the actual situation.

1. Fundamental measures

Wherever the environment is dirty and messy, cockroaches are rampant. Therefore, improving hygiene and managing the environment are fundamental measures. To kill indoor cockroaches, we must first improve sanitation and clear cockroach habitat conditions, and carry out extensive hole-blocking and "eight inspection" activities to remove ootheca and cockroach traces in cockroach habitats. Cockroach traces refer to insect corpses, remaining limbs, bodies, wings, molted skin, cockroach droppings, empty and deflated egg sheaths, etc. "Eight checks" refers to: first check table, second check cabinet, third check chair, fourth check mouth (sewer outlet), fifth check pool (washing tank), sixth check case (food processing chopping board), seventh check seam, eight check Check piles (coal piles, firewood piles, debris piles). Cockroaches like to hide in cracks and holes. Taking advantage of the living habits of pests, you can use putty, cement or silica gel to block gaps and holes so that cockroaches have no place to hide.

Putting poisonous bait is a commonly used and simple method to kill cockroaches, but to use it properly, the trick is "less amount, more points, "Wide area" means that there are more poisoning points in a room, the amount of medicine used at each point is smaller, and the distribution area is wider. In this way, cockroaches can eat the poison bait when they crawl out from their habitat, and the killing effect is obvious. In order to prevent the poisonous bait from becoming ineffective due to moisture, it is advisable to place the poisonous erbium particles in bottle caps. Use insecticide-containing chalk to mark areas where cockroaches roam. Use a pen to draw circles or "wells" around the cracks, holes and corners where cockroaches live and where they often move, so that the cockroaches will be poisoned by the painted powder when they come in and out. The painted line should not be too thin, but should be a thick line of 2-3 cm.

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

Otherwise, there will soon be cockroaches in the new house. Cockroaches cannot fly. They rely on transportation and luggage, packages, furniture and other goods to spread, causing regional and even international spread.

In addition:

1. Fresh cucumber repels cockroaches. Put fresh cucumbers in the pantry so cockroaches won't come near it. After fresh cucumbers have been stored for two or three days, cut them into pieces to continue to emit the cucumber smell, which can also effectively repel cockroaches.

2. Fresh peach leaves repel cockroaches. Place the newly picked peach leaves in a place where cockroaches often hang out. Cockroaches will avoid them when they smell the smell of the peach leaves.
