Crush eggshells in a blender until they form a fine powder. Eggshells are high in calcium, which is beneficial to the soil in the garden. The shells may need drying for a few minutes in a low oven to ensure they are completely dry and able to blend easily. Pieces of eggshell with jagged edges work well as slug and snail deterrents. The pieces can be placed around your vegetables.
