Do you smoke? or know anyone who does?
If you can get hold of a few cigarette butts (already smoked ones are best) put a bunch of them in a container with water (about 4 or 5 butts per cup of water) leave it overnight or until it turns a light tea colour. Put it in a spray bottle (butts removed) It makes a wonderful and affective pesticide!!
(Please test solution on a small part of the plant, to make sure it won't discolur it)
