Another way for cockroaches to enter their homes is to bring them in. For example, if someone at home comes back from a business trip, cockroaches are likely to take them home in suitcases. Or the boxed items you bought in the supermarket may contain cockroaches.
Methods of killing cockroaches:
1. Keep the house clean and tidy at ordinary times. Leftover meals should be handled in time, and fresh fruits and vegetables should be sealed and preserved.
2. It is best to check suitcases, shopping bags, packing boxes, etc. Make sure there are no cockroaches before you go in every time you take it home.
Buy some drugs to kill cockroaches and use them according to the instructions.
4. Soap can also kill cockroaches. When we spray soapy water, a film can be formed to cover the respiratory system of cockroaches' abdomen, so that cockroaches can't breathe and suffocate, thus achieving a sterile and harmless green cockroach killing effect.
