Soft-bodied and slimy, slugs, Agriolimax spp. and Arion spp., and the
slime trails that they leave are common in many strawberry plantings.
garden slug. Most slugs in strawberries range in length from 1/2
to 1 1/2 inches (12 - 36 mm).
Slugs damage fruit by eating deep holes into the surface of berries. Slugs
that damage strawberries in Illinois in the spring and early summer hatched
from eggs deposited in strawberry plantings the previous fall. Conditions
that favor egg-laying in the fall include the continuous presence of straw
mulches. Slug survival and fruit damage in the spring are greatest in
dense, wide rows and when overcast and rainy weather creates continuously
moist conditions in strawberry beds.
Removal of straw mulch after harvest, summer renovation, and delaying
fall mulching as long as is practical are effective steps in reducing
slug populations. Slug baits that contain metaldehyde may be used in strawberries
only if the baits are applied to the soil surface (and to mulch) and do
not contact plants.
