Pest Control Made from Eggshell Powder
This works as an organic pesticide because it gets under the shells of beetles and acts like bits of glass to cut them up and kill them. Snails and slugs will also die if they slink across it, and it works as a deterrent. Well guess what, eggshells work the same way. Allow the eggshells to dry out before crushing them. Grind the eggshells into a powder using a mini food chopper or a coffee grinder.
