Biological killing mechanism:

　　1. Infection : The pheromone in the rubber bait attracts cockroaches to actively feed and infect the virus. The virus enters the sputum and proliferates in the sputum cells, causing the sputum cells exposed to the virus to rupture and irreversibly die.

　　2. Horizontal infection: The body is infected with dead cockroaches, and the virus is successively infected, reaching the peak of death in 3-15 days.

　　3. Vertical infection: The infected female cockroach transmits the virus to the next generation through the egg sheath, and the infected egg sheath cannot hatch.

　　Two-way infection produces a “Domino” chain reaction, one disease, the disease, the population, the adult eggs, and the net.
