  1. Shake well before every use.
  2. Spray directly onto the affected leaves as well as underneath the leaves.
  3. Do this on a cloudy day or in the morning/night.
  4. Spray the plant only once and wait a few days to see if you need another application.
  5. Most often, you'll only need one or two applications.
  6. Wait a few days for harvest so you don't get any spicy residue from the cayenne.

Why This Works:

The combined scent of mint and garlic repels bugs away, making sure to keep them away for good!

Cayenne pepper will also repel the insects, and can also kill a lot of them, so if they rub up against the plant or taste it, they will die.
