Citrus peels—especially from oranges, lemons, and limes—contain natural oils that pests hate. When made into a simple spray, they act as an effective, chemical-free bug deterrent for plants, pots, and even indoor corners.
Ready to use your kitchen waste to protect your plants? This trick works wonders.
Why Citrus Peels Repel Insects
Citrus peels contain limonene, a natural compound found in the rinds of citrus fruits. Limonene:
- Disrupts insect nervous systems
- Masks scents that attract pests
- Deters ants, aphids, whiteflies, fungus gnats, and even mosquitoes
- Leaves a fresh, clean scent—no harsh chemical odor
It’s especially useful in organic gardens or indoor spaces where safety matters.
