Preventing and Managing Infestations
Snails and slugs feed on a wide variety of living plants and decaying vegetation. As they eat, they create irregular holes with smooth edges in leaves, vegetables, flowers and succulent plants. They also like to chew on the fruit, foliage and young bark of some trees, particularly citrus. Once a food source is found, these pests will often return to feed at night or on cloudy days. Look for the silvery trails they leave behind to confirm their presence.
Snails and slugs live in areas where abundant ground cover and vegetation provides ideal moisture levels and shelter. This is why they can be a problem on the edge of a crop with a weedy fenceline. Good hygiene, weed control and removal of refuges can reduce the problem over time. Be aware, though, that pest problems may increase in the short term after this process, as the pests will no longer have the weeds for food or shelter.
