Slugs can first be prevented by introducing some physical barrier between them and the plant. This barrier can go around each individual plant or the entire perimeter of the garden.
These barriers can include:
• Ring of copper wire
• Diatomaceous earth
• Lime
• Sawdust
Slugs have poor interactions with each of the previously listed items and it can kill them or turn them away from your plants.
Attracting or introducing various predators can help control populations and reduce the manual workload.
Predators include:
• Nematodes
• Toads
• Frogs
• Beetles
• Birds
Slugs can be manually removed from your garden by venturing out when the sun is low or even at night.
