Cockroaches have the bad habit of spitting and excreting while eating, and will secrete smelly liquid. In their activities, they can not only carry more than 40 pathogens, such as Leprosy, Yersinia pestis and Shigella dysenteriae, but also are important vectors of intestinal diseases and parasitic diseases, and their secretions and feces contain a variety of carcinogens.

Exclusion method:
1, use a small-caliber long-necked glass bottle, put some sweet food in the bottle and coat the bottle with sesame oil. The cockroach got into the bottle and it was difficult to climb out because the bottle wall was slippery.
2. Use the habit of cockroaches to drill cracks, use a paper box with some cracks on the lid, coat the box with glue, and sprinkle some fresh bread crumbs to let cockroaches get in and steal and get stuck.
3. Take advantage of the habit that cockroaches like to scrape dirt off their backs on hard objects, and sprinkle some hard and sharp diatomite in the corner of the room. Cockroaches go there to rub their bodies, and too much wax oil will be wiped off the surface. It causes a lot of water loss in cockroaches and dehydration to death.
4. You can also put out cockroaches by interfering with their feeling of external vibration. For example, as soon as you see a cockroach, you can immediately make a hissing sound with your mouth and then pat it quickly, which makes it easier to kill it.
5. Chemical drugs can also be used to deal with cockroaches. In places where cockroaches live and move, spraying chemicals can kill cockroaches.
