There are mice in the house. Ask what to do ...

Buy rat poison first, the simplest one, and put it in the place where rats are most frequent.

Second, you use big bags, the deeper the better. Rats are super nearsighted, and they usually go in and out with their noses. Every time it enters the room, it likes to walk against the corner, because its poor eyesight requires a sense of security, and if it leaves the room, it will go back the same way. When you know this feature, you can only wait for it to come in, just like waiting for a rabbit. If there are two of you, the other dares to let the mouse go out and let it go home to catch it. This method requires patience, but it is practical.

Third, mice have the habit of adding fur, which is a bit like cats. I suggest you buy some car oil. The thicker the better, the darker the better. Then you find some plastic paper, coat it with oil, and put delicious apples or biscuits in the middle of the plastic paper coated with oil. The more fragrant the better. Then put it in a place where rats often haunt. When a mouse steps on waste engine oil, it will add feet and hair with its mouth, so the mouse will be poisoned and die. This method is very good, that is, the dead mouse will feel sick if it can't be found for a while.

Third, keep cats.
