Yes, the leaves make a very handy spray against various pests, but you have to be careful. A friend of mine swears by it, spraying it on everything, including vegies. He remains perfectly healthy. Another friend won't use it on vegies because of the oxalic acid content.
Chop up the leaves, simmer in water for about half an hour, strain, add some liquid soap, and that's it. Make sure you label the container.
