Teach you several ways to kill cockroaches.

First, the habits of cockroaches

Cockroaches are the oldest insects. Cockroaches were active on the earth 350 million years ago and are the oldest and most successful insect population in the world. Cockroaches carry at least 40 kinds of bacteria, nearly 10 kinds of viruses, 7 kinds of parasitic eggs and 12 kinds of molds. According to the investigation, the detection rate of Aspergillus flavus in cockroaches and cockroaches is 29-50%, which are teratogenic and carcinogenic substances. Cockroaches do evil, eat everything and are everywhere. The food that roaches climb over will leave a disgusting smell. Often bite people's beloved clothes; Accidents such as cockroaches biting people and getting into ears often occur. Cockroaches are omnivorous insects, and they like food eaten by human beings. Such as books, leather, clothes, soap, etc. I also like to eat; Often climb into sewers, garbage dumps, toilets to eat feces, animal carcasses and other corrupt organic matter. Cockroaches are found in almost all places where people live and move. There are at least four basic conditions for cockroaches to settle in a place: a warm climate; Humid environment; The food source is rich and has a multi-gap structure. Obviously, if we try to eliminate these conditions, we can effectively prevent the breeding of pests. After the male and female cockroaches mate, the female cockroaches grow a pod-like thing called an egg sheath on their tails, and the eggs are laid in it. A few females can produce more than 10 and more than 90 egg sheaths. In an egg sheath, at least 10 cockroaches can be hatched, and at most more than 50 small cockroaches can be hatched, which is related to the species of cockroaches. So it is very important to destroy the egg sheath of cockroaches. Killing an egg sheath is equivalent to killing dozens of cockroaches. Cockroaches lie down during the day and come out at night. During the day, they mostly hide in "cracks, holes, corners and piles" of walls and furniture near water sources, food sources and heat sources. When we kill cockroaches, we should pay attention to these places as the focus of spraying drugs and putting cockroach bait. Get the medicine in place and get twice the result with half the effort.

Second, several methods to kill cockroaches

At present, the commonly used effective methods include throwing poison bait, spraying insecticide, smearing cockroach-killing chalk, dusting powder and spraying insecticidal smoke. , and choose to use according to the actual situation. In addition to chemical methods to kill pests, cockroaches can also be trapped and killed by physical methods such as sticking boxes and catching bottles.

1, radical measures

Where sanitation is dirty and messy, cockroaches are rampant. Therefore, doing a good job in sanitation and managing the environment are fundamental measures. To kill cockroaches indoors, we must first do a good job in hygiene, remove the habitat conditions of cockroaches, extensively carry out the activities of plugging holes and plastering seams, and remove the egg sheaths and cockroaches from their habitats. Cockroach marks refer to insect carcasses, residual limbs, corpses, wings, molting, cockroach excrement, empty egg sheaths, etc. "Eight inspections" refers to: one inspection table, two inspection cabinets, three inspection chairs, four inspection ports (sewer ports), five inspection pools (washing pools), six inspection boxes (food processing boards), seven inspection seams and eight inspection piles (coal piles, firewood piles and sundries piles). Cockroaches like to drill holes and hide cracks. Taking advantage of the living habits of pests, cracks and caves can be blocked with putty, cement or silica gel, so that cockroaches have no hiding place. For those kitchens with seriously damaged interior walls and outdated furniture, it is necessary to completely repair the houses and update the furniture in order to eliminate cockroaches.

2, reasonable spraying to kill cockroaches

Cockroaches often drill into cracks and dig holes to hide. Therefore, when spraying medicine with a sprayer, it is necessary to spray medicine around gaps, holes and corners, so that the spraying effect is good and the medicine is saved. Cockroaches are reptiles. Don't spray them into the space and don't wear masks. Spray around.

3. Put the cockroach bait.

Putting poison bait is a common and simple method to kill cockroaches, but if used properly, the trick is to "put more poison spots in a room, with less dosage and wider distribution". In this way, cockroaches can eat poison bait when they climb out of their habitat, and the killing effect is obvious. In order to prevent poison bait from failing due to moisture, it is advisable to put poison bait erbium particles in the bottle cap. Use chalk drawings containing pesticides in cockroach activity places. Around the crevices, holes and corners where cockroaches inhabit and often move, the word "well" is used to poison the powder marks smeared when cockroaches come in and out. The drawn road should not be too thin, it should be a thick line of 2-3 cm.

4, move to 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. Warning citizens: When moving, please be sure to remove cockroaches and their egg sheaths hidden in old furniture, clothes, books, cartons and wooden cases, otherwise, cockroaches will soon appear in new houses. Cockroaches can't fly They spread through vehicles and luggage, parcels, furniture and other items, leading to regional and even international spread.
