Is there any good way to get rid of cockroaches completely?

When I was studying, I used to kill cockroaches in the dormitory. Insecticidal water was sprayed in every corner of the room, and a whole bottle was sprayed directly. The room was closed for a day. When I come back at night, the ground is dead. I look at my scalp and feel numb, but when I sleep at night, I can still hear the sound of crawling. I think it may have been smoked to death. Just wanted to think, half-dead Xiao Qiang fell directly from the upper bunk bed and died.

Cockroaches are found in my family every September, but not at other times. One will be found every few days or weeks, sometimes in the living room, sometimes in the master bedroom or study, asking for help. In this case, where should I put the cockroach bait? Every time I see a cockroach, I tremble with my husband.

Our house is rented, and we never cook with fire. First I saw a big cockroach at the weekend, and then the next day I saw two cockroaches near the sewer pipe of the washing machine and the bathroom. But when we ordered the medicine, we didn't see this article, which led to the reverse gap and hinge where you said there was no medicine. If you open the cupboard, you can still see a lot of cockroach droppings. Yesterday, you also swept a cockroach egg. After taking the medicine, I saw three dead cockroaches the next morning, and one of them died on the pillow. On the third day, I saw a live cockroach. Do you need some cockroach medicine? Because the main things are given by the living room, only a few glue baits are ordered in the cupboard.

In addition, does the landlord have any good ways to limit the range of cockroaches as long as they don't sleep? After all, sleeping every night is really scary, so just play and see if there are any cockroaches that affect sleep.

I once rented a house like a cockroach nest and put it in the corner with a boxed bait (a cracked plastic box with a bait block similar to a rice crust, and the medicine was imidacloprid). Later, it was not easy to use glue bait in other places where there were not so many cockroaches.
