I used a habanero pepper spray to kill mites on my plants last summer. Just chop or blend 5 habanero peppers with 2 cups of water. Simmer in small pot for 10 min Strain. Mix with 5 gallons of water and spray. But BE VERY CAREFUL cover youself up and dont get that shit on your hands or in your eyes. It works, that I have seen with my own eyes but be very cautious and cover yourself as much as possible.
