Swany, do you mist them only with water? I usually use a little vinegar mixture to keep the aphids and such off of my garden plants, but some plants can not tolerate it.
Little bit of tobacco soaked in the mix works also. Yes vinegar.
To all the hot pepper oils release a bodies natural high called endomorphins which also alleviate such things as arthritic pains and swelling. Many other benifits to releasing endomorphins. Many in South America actually soak their arthritic hands in Habanero before work each day.
