|The box says for "the organic control of white butterfly". Well, there is nothing "natural" about it. It is not of or occurring naturally from mother earth. But then again, it is not extruded from chemicals. Well, perhaps all the plastic is, but that is not leaving a residue.|
So, how does it work? It can be either solar-powered, or battery-powered. From the box:
The white cabbage butterfly especially favours plants from the Brassica family, eg cabbage, cauliflower, and broccoli. The caterpillars are very destructive and can destroy plants in a very short time. WCBs are very territorial and will not lay eggs where they see another WCB as they don't want their young to compete for food.
Round and round the garden, like a butterfly ...
