Using the habits of cockroaches, people have created
Taking advantage of 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 to the mouth of the bottle. The cockroach enters the bottle, because the bottle wall is very slippery, it is difficult to climb out.
Using the habit of cockroaches love to drill gaps, use a carton, cover it with some gaps, apply viscose to the box, sprinkle some fresh crumbs, and let the cockroaches get in and eat it and get stuck.
Taking advantage of the habit of cockroaches that like to scrape off the dirt on their backs on hard objects, sprinkle some hard and sharp-edged diatomaceous earth in the corner of the room. When cockroaches go there to rub their bodies, the layer of wax oil on the surface will wipe off too much. As a result, a large amount of water in the cockroach's body is lost and dehydrated to death.
You can also use methods that interfere with the cockroach's perception of external vibrations to extinguish it. For example, when you see a cockroach, you immediately make a "shush" sound with your mouth, and then quickly slap it, which is easier to kill it.
You can also use chemical drugs to treat cockroaches, spray 5/1000 of dichlorvos, or 3/10000 of deltamethrin, boric acid powder, etc., or put a few cockroach slices to kill cockroaches. A kind of pyrethroid insecticide called "roach killer" has been tried in the galley of cargo ships, oil tankers and Yangtze River passenger ships of the Bureau of Shipping. 60 cubic meters of liquid was sprayed with 300 milliliters of liquid in the cabin, and the cockroaches immediately became excited and fell out. Some unconscious and undead died after a day, and some tenacious ones did not survive for five days.
Recently, scientists at the National Institute of Genetics in Japan discovered that toads (commonly known as toads) are the fate of cockroaches. The small animal breeding house in this house was once infested with cockroaches, and people were helpless. Later, some toads were released in the breeding house, and soon, the cockroaches disappeared. After dissection, it was found that most of the toads' stomachs were composed of cockroach remains.
A scientist in Kansas has developed a sex scent capture device that traps male cockroaches, mainly a toxic sticky paper with a smell. This smell is exactly the same as the smell of the sex pheromone secreted by female cockroaches, which can lure male cockroaches to the sticky capture paper and poison them. With a little bit of this sex pheromone, male cockroaches within a range of about eight meters can jump into this trap device within five seconds. Dutch scientists have also synthesized a similar sex pheromone. This indicates that the complete eradication of cockroaches is not far away. One day, people will widely use these ideal methods to make cockroaches that endanger human health "cut off offspring".
Not long ago, foreign researchers have also developed a synthetic chemical that can release a special aroma and induce cockroaches to engage in sterile mating. In the long run, cockroaches will not be able to pass on their lineage.
