Tabacco Juice recipe
Try this it works great. I use tis when i get them
Take 3 strong ciggeretes soak them over night in water and the hottest hot sauce you can find.
Boil it for 2 to 3 miniutes, let it cool off the strain using ladies nylon socks and spray the plants 3 to 4 times a week. You can add safer soap if you like to the mixture.
(make absolutly sure you use gloves/face protection while handling and spraying)
