So I have made an organic spray mix to spray my veg and hopefully either kill or deter pests.
It is made from orange peel, black pepper, a little washing up liquid and super hot chillies.
I have sprayed two broad beans and two leaves on my sprouts to see if there is any effect on the plant itself.

Judging by the fact my fingers are burning like mad I suspect what black fly are on the broad beans will be in absolute angony, lets see if it deters caterpillars for which it is supposed to good at and if not I would hate to be them after nibbling a leaf

I use black pepper to keep ants out of the house so that makes sense, but what does the orange peel do?
