SLUGS are soft-bodied
mollusks that are like snails without
shells. They have flabby, slimy bodes,
usually 1 to 2 inches in length at maturity. Color varies from white to gray, yellow, or brown-black.
Slugs eat leaves, soft fruit, and stems of many different plants, including seedlings. Plants suffer large ragged holes, and a slimy trail may be visible on leaves or soil. Slugs hide in damp, dark spots during the day and feed at night or on cloudy days.

OPTIONS FOR SLUG CONTROL
There are usually several management options for solving any pest or disease problem. Use the non-pesticide approach whenever possible, saving pesticide use as the last line of defense. If a pest is identified at a damaging
level, select a control targeted to the problem. This is called Integrated Pest Management or IPM .
PREVENTING SLUG INFESTATIONS
Thoroughly rake out mulch and garden debris once or twice a year to destroy slug
eggs. Select varieties of hosta and other plants that do not attract slugs.
CONTROL DURING SPRING AND SUMMER
Use a combination of
hand-picking, trapping and barriers, and be persistent.
Hand-picking. Use gloves or tweezers to remove slugs by hand. Work at night (with
flashlight) or early morning.
Trapping. Trap slugs with overturned flower
pots, saucers with beer, wet newspaper rolls,
and/or grapefruit rinds. Try different methods.
Diatomaceous earth and other barriers:
Spread the dust around base of plants
uniformly, following package directions. Use a dust
mask, as specified on label. Repeat as necessary.
Iron Phosphate Bait. Scatter granules in a 6 inch band around plants or to damp places where slugs may be
found. The bait is eaten by slugs and causes them to cease feeding and die over several
days. Read Precautionary Statements on package labels and follow all instructions. |

READ THE LABEL BEFORE BUYING ANY PESTICIDE.
Re-read the label before using, storing or disposing of the pesticide the label is the law. Following label instructions will help reduce risks to human health and the environment. |
