How to kill cockroaches completely and keep the environment clean is the most important.

Where the sanitation is dirty and messy, cockroaches are rampant. Therefore, it is a fundamental measure to improve the health and management environment. To kill cockroaches indoors, we must first do a good job in hygiene, eliminate the habitat conditions of cockroaches, and extensively carry out the activities of plugging holes and plastering seams and "eight inspections" to 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 inspection" refers to: the first inspection platform, the second inspection cabinet, the third inspection chair, the fourth inspection port (sewer port), the fifth inspection pool (washing pool), the sixth inspection box (food processing board), the seventh inspection seam and the eighth inspection pile (coal pile, firewood pile and sundries pile). Cockroaches like to drill holes and hide cracks. By taking advantage of the living habits of pests, you can block gaps and caves with putty, cement or silica gel, so that cockroaches have nowhere to hide. For those kitchens with severely damaged interior walls and outdated furniture, houses must be completely repaired and furniture updated to eliminate cockroaches.

2. Spray cockroaches reasonably.

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

3. The trick of killing cockroaches with poison bait.

Putting poison bait is a common and simple method to kill cockroaches, but if it is used properly, the trick is "less quantity and more area", that is, putting 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 the bait from losing its efficacy due to moisture, it is suggested to put the poison erbium particles in the bottle cap. Use dusting powder 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 cockroaches with powder marks painted when they enter and leave. Don't draw the road 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 mushroomed, and a large number of residents have moved into new homes. Warning to the public: When moving, please be sure to remove cockroaches and their egg sheaths hidden in old furniture, clothes, books, cartons and wooden cases, otherwise there will be cockroaches in the new house soon. Cockroaches can't fly They spread through transportation and goods such as luggage, parcels and furniture, which leads to regional and even international spread.
