9. Deter Garden Aphids
Aphids are tiny, sap-sucking pests that can ruin a garden in a matter of days. If you notice these little bugs congregating on your rose bushes or vegetable plants, banana peels can act as a natural deterrent. While scientists aren’t 100% sure why, aphids seem to have a strong dislike for the scent of decomposing banana peels, making them a great organic “keep out” sign.
To protect your plants, cut up banana peels and bury them about an inch deep around the base of the stems. Not only does this provide the nutritional benefits mentioned earlier, but it also creates a zone that aphids prefer to avoid. Be careful not to leave large piles of peels on the surface, as this might attract larger “unwanted guests” like raccoons or squirrels; burying them slightly is the key to keeping the pests away without attracting more.
