Not all slugs are bad slugs though. Some only eat decaying matter and would not feed on a living hosta leaf if its life depended on it. A few types are carnivorous and will feed on other slugs. The slugs we worry about are the ones that feed on our hostas and other plants. This seems to be the highest population.
Some slugs feed on our hostas leaving conspicuous holes in the leaves.
The holes usually are in the middle portion of the leaf blade and vary with the size of the slug. The holes may run along between leaf veins and can be sever enough to skeletonize an entire leaf or almost an entire clump. There seems to be no question that the preferred hosta types are those plants with the species H. plantaginea in the background. We have three options if we don t want slugs to eat our special plants. Ignoring them is not one of the options, but it may be something to consider if we don t mind the occasional hole in our leaves.
