How Do I Organically Stop White Butterfly Grub Eating My Cabbage?
Cabbage Whites are only one of the species of butterflies that will lay eggs on brassicas. Manual control includes examining the leaves of the plants regularly, every one to three days, for clusters of the eggs, usually, though not always, on the undersides of the outer leaves. These clusters can be ‘rubbed off’ with the fingers. You can perhaps enjoy the pleasure of picking off the caterpillars (which must be destroyed) but if they are at that stage, you will not be able to get to many of the grubs which have infested the heart of the plant without ruining the plant in the process. Fine mesh netting will prevent the butterflies reaching the plants, though this must be frequently checked that it is not affecting the growth pattern of the plants. Another effective treatment is Derris Dust, in itself a natural product, which kills the caterpillars and many other pests. Some other advice you may find useful is on the Web of course.
