Repair the screen window, put rat poison on the windowsill, store room, kitchen and other places for storing food, and arrange rat boards and mousetraps in corners and dead corners. The specific steps are as follows:

1. Prepare window screen patches, rags, special repair tapes and scissors.

2. Trim the hole edge with scissors to make the hole complete.

3. Wipe around the hole with a towel to remove dust. Make the hole cleaner.

4. Select the patch with appropriate size. There are three sizes of screen window repair tapes available in the market, namely, large 10cmX 10cm, small 7cmX7cm and strip-shaped 50cm. Select the appropriate size patch according to the shape.

5. Tear off the adhesive and paste the patch from the room. Tear off the double-sided adhesive tape and stick it on the small screen window. After the double-sided tape is torn off, press it a few more times, which will stick more tightly.
