Slugs eat twice their body weight every day.
Slugs can eat up to twice their weight (or more) depending on the availability of food. A typical slug weighs around 300 milligrams so it doesn’t take a ton of plant matter to sustain these animals but their daily intake needs to be averaged over time.
Slugs eat mainly vegetation, mushrooms and rotting plants but many varieties eat dead animals and other slugs. Most slugs will eat from a range of over 500 different plant types and that means as a vegetable grower, they will be eating what you grow.
