Why Cayenne Pepper Repels Bugs
Cayenne pepper contains a powerful compound called capsaicin. When insects ingest or come into contact with capsaicin, they experience extreme discomfort and pain.
Capsaicin activates sensory neurons in insects that detect heat and pain. This causes an intense burning sensation, deterring bugs from sticking around or feeding on your plants.
In addition to the spicy heat, cayenne pepper also contains antioxidants that can disrupt the nervous systems and cell membranes of soft-bodied insects like aphids.
Studies have shown cayenne pepper successfully repels:
However, cayenne will not harm helpful pollinators like bees. It only affects insects that chew, feed on, or otherwise damage your plants.
Now let’s look at how to harness the power of cayenne pepper in your own garden.
Will Cayenne Pepper Hurt My Flowers?
If you’re worried about hurting your ornamental or edible flowers with cayenne pepper spray, don’t be! Cayenne will deter insects from munching on your blossoms but will not damage the flowers themselves.
Most flowers tolerate diluted cayenne spray just fine. However, it’s always best to test a small portion of the plant first before spraying the entire thing.
Watch for 1-2 days for any reaction, such as wilted or dried petals. If no effect, the flowers should be safe for cayenne application.
When spraying flowers, stick to early morning or evening applications when pollinators are inactive. This prevents the spray from coating bees and butterflies.
Also, rinse blossoms thoroughly with water after application to prevent pollinators from being affected by pepper residue.
With proper precautions, a cayenne spray of 2 tablespoons cayenne powder per 1 gallon of water, plus 1 tsp dish soap, can safely deter pests from your flowering plants.
The capsaicin in cayenne pepper irritates and repels chewing, sucking, and boring insects that damage flower buds and petals. Yet it does not appear to harm the flowers themselves.
So go ahead and use cayenne spray to keep aphids, beetles, caterpillars, thrips, and other pests away from your beautiful blooms! With a few simple precautions, cayenne can protect flowers without hurting these delicate plants.
Creating a Homemade Cayenne Pepper Spray
Whipping up a homemade cayenne spray takes just a few simple ingredients. Here’s what you’ll need:
- 2 tablespoons cayenne pepper powder or 5 tablespoons crushed red pepper flakes
- 1 gallon of water
- 1 teaspoon dish soap (Dawn or castile soap work best)
- Saucepan with lid
- Spoon for mixing
- Fine mesh strainer
- Spray bottle
- Add the cayenne pepper and water to the saucepan.
- Bring the mixture to a boil over high heat. Then reduce heat and let it simmer for 15 minutes.
- Remove the pan from the heat and allow the mixture to cool completely. This allows the flavors to infuse.
- Once cool, strain the mixture through a fine mesh strainer to remove any solid pepper pieces.
- Transfer the strained liquid to a spray bottle, preferably one with a targeted spray nozzle.
- Add 1 teaspoon of dish soap and shake gently to combine. The soap helps the spray stick to plants.
- Label your cayenne spray and store any leftovers in the refrigerator for up to a week.
And that’s it – you’ve made an all-natural bug-busting cayenne spray!
Want to make your cayenne spray even more powerful? Consider adding one of these optional extras:
- 1 bulb of crushed garlic – repels aphids

How to Apply Cayenne Pepper Spray
A light coating of cayenne spray will protect your plants from insect invasion. Here are some tips for effective application:

What to wear: Gloves, goggles, mask, and long sleeves to protect yourself. Avoid inhaling vapors.
After handling: Wash hands, equipment, and any vegetables thoroughly after harvest.
Be sure to spray both sides of leaves and reapply after rain or watering. Consistency is key for optimal protection!
Precautions When Using Cayenne Pepper Spray
Cayenne pepper is natural, but also requires some safety precautions. Here’s how to prevent potential problems:
- Spot test on a small area first to ensure plant compatibility.
- Keep away from eyes and mucous membranes.
- Use gloves, goggles, and a mask to prevent skin irritation.
- Avoid breathing in vapors from the spray. Use a mask if necessary.
