Things You'll Need
Instructions
Pour 2 or 3 inches of clean sand into a large jar with a screw lid.
Pour a small amount of water onto the sand until it is thoroughly dampened.
Pour off any excess water from the jar.
Add between two and five drops of carbolic acid to the sand. Carbolic acid is available at drug stores, and it helps prevent fungal growth.
Place a small dish or jar lid on top of the sand. Set your insects on top of the dish and screw on the jar lid, leaving them in the jar for between 24 and 48 hours. They are easy to bend once you remove them.
