The Q&A Archives: Hosta Pest Control

Question: We transplanted some varigated hosta to our backyard in early spring. Now it seems as if something is eathing the leaves that are closest to the ground. Is there any recommended pest control for this type of problem? Is there a possibility that it is the soil and not an insect?

Answer: If the damage includes roots, it may be caused by voles. These can be controlled by trapping. If the damage is only on the leaves, I would suspect slugs. These eat at night and leave silvery slime trails. These can be controlled by a variety of measures: trapping, baits (read and follow label instructions), hand picking, and also by sprinkling diatomaceous earth (a powder sold in garden centers) on the soil surface right around the plants.
