At present, the commonly used effective methods are putting cockroach poison bait, spraying insecticides, smearing cockroach-killing chalk, spraying powder, spraying insecticidal smoke and so on, and choosing to use them according to the actual situation. In addition to chemical methods to kill pests, cockroaches can also be trapped by physical methods such as sticking boxes and trapping bottles.

1. Treatment Measures

Where environmental hygiene is dirty and disorderly, cockroaches are rampant. Therefore, to do a good job in sanitation and improve the environment are the fundamental measures. To kill indoor cockroaches, we should first do a good job of hygiene and remove the cockroach habitat conditions, carry out extensive activities of blocking holes and smearing seams and "eight inspections" to remove the cockroach habitat egg sheath and cockroach tracks. Cockroach marks refer to corpses, remnant limbs, bodies, wings, molting, cockroach excrement, empty egg sheath, etc. "Eight checks" refers to: one checks table, two checks cabinet, three checks chair, four checks (sewer outlet), five checks pool (washing pool), six checks (food processing board), seven checks seam, eight checks pile (coal pile, firewood pile, sundry pile). Cockroaches like to drill holes and cracks. Using the life habits of pests, we can use oil ash, cement or silica gel to plug gaps and caves, so that cockroaches have no hiding place. To eliminate cockroaches in kitchens with severely damaged interior walls and obsolete furniture, it is necessary to thoroughly renovate houses and upgrade furniture.

2. Rational spraying of cockroaches

Cockroaches often live in holes and seams. Therefore, when spraying with sprays, they must be sprayed on the seams, holes and corners, and sprayed around them, so that the spray effect is good and the medicine is saved. Cockroaches are reptiles. When spraying insecticides to kill cockroaches, don't spray them into space or face masks. Spray them on all sides of the walls.

3. The knack of putting poison bait to kill cockroaches

Poison bait is a common and simple method of killing cockroaches, but to use it properly, the trick is "less quantity, more points, a wide range", that is, more poisoning points in a room, less dosage at each point, a wider distribution. In this way, cockroaches can eat poison bait when they crawl out of their habitat, and the killing effect is obvious. In order to prevent the bait from damp failure, erbium particles should be placed in the bottle cap liner. Use chalk containing insecticides to mark cockroaches'activity sites. When cockroaches move in and out of their habitats, they are poisoned to death by smearing powders around cracks, holes and corners and where they often move. The painted road should not be too thin, but should be 2-3 cm thick line.

4. Do not forget cockroaches when you move to a new house

In recent years, urban buildings have sprung up like bamboo shoots after rain, and a large number of residents have moved into new houses. Caution: When you move, please be sure to remove cockroaches and their egg sheaths hidden in old furniture, clothes, books, cartons and wooden boxes, otherwise, cockroaches will soon appear in the new house. Cockroaches can't fly. They spread by means of transportation and goods such as baggage, parcels, furniture and so on, resulting in regional and even international spread.
