Egg-celent Solution: Pest Control & Other Uses of Eggshells

Here are some solutions you won’t have to ‘shell’ out any cash for. That joke might be bad but we’ve listed out a few excellent uses for eggshells around the house and garden.

Around the Garden

Eggshells contain calcium and other minerals. Crushed eggshells can be scattered around the garden to give the plants nourishment.

Pest Control

They serve as organic pest control for treating insects, mites and weeds. They are also 100% effective against slugs, snails and other soft-bodied pests. You can make a fine powder out of it and sprinkle it on leaves to keep beetles away. For slugs and other worms, sprinkle the eggshell pieces on the ground at the base of the plant.

Seed Starters

Since they are bio-degradable, they make excellent seed starters. Sterilize the deep shell halves by boiling them and then make a tiny hole for drainage. Place the seeds and soil. When sprouts begin to appear, plant them into the soil (eggshell and all).

Calcium Boost for Tomatoes

They are also one of the greatest natural sources of calcium carbonate. The tomato plant is susceptible to blossom end rot which is caused by calcium deficiency. You can either add the crushed eggshells at the time of setting the tomato plant or can even add it to the soil around the plant.

Around the House


Eggshells contain sulphur which is harmful to the lizard. Birds beaks also contain sulphur and lizards can smell it so they stay away. It is also believed that lizards take the presence of eggshells to mean there are larger predators around and this scares them away. Place eggshells near windows and doors so lizards don’t event the house.


Powdered eggshells make a great, nontoxic abrasive for those stubborn stains on pots and pans. Just mix it with some soapy water and you’re good to go.

Coffee sweetener

Before brewing your ground coffee, add some eggshells to it. This makes it taste less bitter as the calcium carbonate in the eggshell absorbs some of the acids in the coffee.

Laundry whitener

Put some eggshells in a muslin bag or a tightly-woven cloth bag and throw it in the washing machine when you put in a load. This will brighten your white clothes.

With some paint and glue, you can create so many cute little things with eggshells. You can colour and stick pieces of the shell around your photo frames or you can make tiny little vases or candle holders with them.

Beauty Bonus

You can also use eggshells to make a nourishing, skin-tightening face mask. All you have to do is combine two teaspoons of powdered eggshells with an egg white. Apply this mixture to your face and wash it off after 15 minutes.
