1. Expelling insects from the ear: If a small insect enters the ear canal, you can take some Sichuan peppercorns, soak them in oil, and drip a small amount into the ear. The insect will exit on its own.
2. Ant-proofing the kitchen cabinet: Placing dozens of fresh Sichuan peppercorns in the kitchen can effectively prevent ants.
3. Moth-proofing woolen fabrics: Woolen fabrics are susceptible to moth damage. By sprinkling some Sichuan peppercorns in a clothes chest, you can prevent insects from infesting them.
4. Preventing oil from boiling over: When deep-frying food, add a few Sichuan peppercorns once the oil reaches its boiling point. The boiling oil will subside.
