Killing may not kill the hard-shell egg sheath, but a certain number (dozens) of larvae will hatch after a few days; Some species don't drag the egg sheath, and males don't carry eggs, so killing cockroaches usually doesn't release a lot of eggs. Besides, you will dispose of the body immediately after killing the cockroach, and it will be fine.
Biological cockroaches will prevent foreign bodies from invading their bodies, and the first line of defense is the epidermis. The outermost waxy layer of the epidermis is impervious to water and needs to be wiped frequently to keep it clean. Bacteria in food can also be eaten when eating, but insects have a very shelter called a peritrophic membrane.
The food you eat will be wrapped in a semipermeable membrane and separated from the intestine, so bacteria can't directly contact the intestinal wall of insects. Although the foregut has no peritrophic membrane, it is protected by chitin inner epidermis. Therefore, healthy cockroaches are clean except for intestinal contents.
Extended data:
Cockroaches will be called the first of the four pests by the people.
1. Cockroaches are extremely fertile. A cockroach can breed tens of thousands of cockroaches a year, and female cockroaches can lay eggs permanently only by mating once.
Cockroaches are extremely destructive. Cockroaches eat everything, wood, wires and dirt, destroying people's means of production.
3. Cockroaches carry germs. They vomit while eating, carry germs, pollute food and pose a great threat to human health.
4, cockroaches have strong adaptability and are difficult to kill. Cockroaches are extremely resistant to drugs. Generally, the cockroach killing devices or cockroaches killing drugs bought in the market are all temporary solutions, and they cannot be removed at all.
