Natural Remedies for Orchid Pests

Just like any other plants and flowers, orchids are also prone to pests and diseases. Good thing is you can always resort to home remedies or natural products to ward off critters that destroy these gorgeous babies. Most of these items can just be found lying around your home.


Cinnamon smells great and it is a natural fungicide as well. This makes it very useful if you want to protect your orchids from fungus and even bacteria. If you want to use this then all you have to do is trim down your orchid leaves. After you have done this, you can sprinkle some cinnamon onto the leaves and this will help you to treat the fungus as well as helping to deter any pests that might be present.

Antiseptic Mouthwash

Mouthwash not only fights off bacteria that causes bad breath, it can also do wonders for orchids. This usual home product can help fight bacterial infections and ward off insects that try to destroy your orchid.

Spray directly onto the affected area of the orchid and let sit for five minutes. Then tip the orchid so the remaining liquid drains off. You can also spray your orchid once a week to prevent any insect infestations. Be sure to only use the unflavored, or gold, version of the mouthwash as the flavored versions have extra additives that may be harmful to your orchid’s health.

Another common household item which can be used to kill off orchid pests is alcohol. This product is effective since insects do not develop resistance at all to alcohol.

Soak a cotton swab in 70 percent isopropyl (rubbing) alcohol and dab scale, mealybugs, mites and aphids off orchids. The alcohol dissolves the insect’s waxy covering, and is a good tool to reach the pests hidden down in the sheaths and leaf crevices. Pay particular attention to the midrib, other veins and leaf edges. Repeat the treatment at seven to 10 day intervals to remove successive generations.

Another method is to spray alcohol, mixed with a few drops of mild liquid soap, from a misting bottle or small pump sprayer. Avoid strong or excessive amounts of detergent, as this may damage your plants, particularly buds and flowers.

Herbal Water Spray

Plants and herbs are beneficial not just to human beings, but to their fellow plants alike.

Essential oils from sage, thyme, basil, rosemary, mint, rue and lavender repel some insects. To create a spray, take crushed leaves or trimmings, soak in a bucket of water overnight  and strain. Or, dilute store-bought essential oil with water. You can also plant these herbs in your yard to detract insects.
