You may have noticed we have some unwanted guests in our garden. Imported currant worms (or sawflies) are eating all the leaves on the currant bushes.
According to Pesticide Free BC’s website some solutions for dealing with leaf eaters are insecticidal soaps, Bacillus thuringiensis (Bt), and physically picking off the pests. I bought some Safer’s BTK biological insecticide in the hopes that it would kill of the currant worms, but apparently currant worms are neither caterpillars nor flies and cannot be controlled with Bt.
Safer’s Insecticidal Soap might help to kill of the currant worm larvae, but we’ll have to pick off the adults by hand.
Anyone have other ideas?
