1. When you step on a cockroach, you just kill it, but the eggs in the cockroach squirt out. In other words, when you step down and step on a cockroach, thousands of cockroaches in Qian Qian are born, and then these eggs attach to the soles of their owners and hatch at the right time.
2. The spread of bacteria. When cockroaches are trampled to death, all kinds of germs will spread in the air, so there will be various hidden dangers in the indoor environment.
Moreover, germs will enter people's bodies in the process of breathing, leading to pathogen infection and physical diseases. After a cockroach is trampled to death, a new cockroach will appear and eat its body, thus increasing the number of cockroaches.

Hazards of cockroaches:
Cockroaches can be artificially infected with bacteria that cause cholera, pneumonia, diphtheria, gangrene, anthrax and tuberculosis in Asia. Cockroaches can carry many kinds of eggs, such as roundworms, hookworms, beef tapeworms, roundworms and whipworms. They can also be used as intermediate hosts for Echinococcus moniliforme, Hymenolepis brevis, tumor ducts and other nematodes. Cockroaches can also carry many kinds of protozoa, among which four kinds of protozoa are pathogenic to humans or animals, such as amebic dysentery and Giardia.
Because of their wide invasion range and miscellaneous eating habits, they can not only move in garbage, toilets, bathrooms and other places, but also feed on food, so the spread of intestinal diseases and parasitic eggs can not be ignored.
