In order to get rid of the cockroaches in the room, I have put a lot of effort on it. I personally summarized the information on the Internet and combined my own experience. We also welcome friends with other experience to supplement the recommended information. Our goal is to have no cockroach.
To sum up, the main task is to eliminate cockroaches and require everyone to maintain some patience. Specific details are as follows.
Looking for the source from the outside.
The first thing to know is how the cockroach enters the house, whether it exists in the room itself or whether it is from outside. In addition, if it is from outside, it will be propagated in the house very fast.
If it is from outside, there are usually three ways to enter the room.
First, from the sewer, if there is no deodorant floor drain in your house and there is no water seal in the sewer pipe, then it may climb from the sewer entrance at night. The solution to this situation is to carry out sewer maintenance and replace it with deodorant floor drains. (Cockroach can swim, even if it is thrown into the toilet, it can still be alive).
Secondly, the cockroach can fly, and it may fly directly into the room from the open window. Therefore, it is necessary to install screen window and the seal the gap of window by hair pad.
This kind of mat is placed in the gap, which can perfectly block the insect that may climb in, besides, it is cheap. The reason that we need extra mat beside screen window is I found that many insects did not try to fly through the screen window directly, but slowly crawling in from gap of the window. It took me a long time to figure out.
Finally, it may be from the next door, so it is necessary to cooperate with neighbors. It is necessary to observe whether there are cracks on the wall adjacent to the neighbor's house. If there is a crack, it must be blocked with various quick-drying cement. Or you can use the foaming liquid that blocks the air-conditioning hole. Then, we must unite our neighbors together to eliminate them.
These are the ways from outsides, and there are other ways cockroach enters the house. But how to get rid of cockroaches in your house? You can read from it.
