Stop slugs from feasting on your prized hostas, strawberries and lettuces.
Slug Magic pellets contain the active ingredient iron phosphate, a naturally occurring mineral. Once slugs ingest it, they stop eating and die within a few days. Sprinkle on the soil surface near affected plants — pellets remain effective for a full two weeks even if it rains.
Large, irregularly shaped holes in leaves and shiny slime trails across foliage are telltale signs of slugs. These soft-bodied creatures will eat almost any type of plant material, but they are especially fond of tender new growth. In the vegetable garden, slugs target the leaves of salad greens along with newly emerging seedlings; they will eat holes in tomato fruits too.
Slugs range in size from ½–5″ long and they may be orange, gray, black or brown. After overwintering in the soil, adult slugs emerge in the spring and lay hundreds of eggs near the soil surface. Young slugs begin feeding close to where they hatch, but slowly move throughout a garden. Slugs are most active at night and in wet, cool weather. When it’s hot and dry, slugs are rarely a problem. In general, slugs dislike plants with leaves that are glossy, waxy or hairy. They also seem to avoid plants with strong-smelling foliage, such as rosemary, marigolds, and lavender. Slugs are found throughout North America.
