The black slug, although it can cause concern by its presence, does not present any danger in terms of toxicity for humans or domestic animals. Unlike some other creatures, black slugs (sometimes called Arion in Europe) do not have venomous glands or mechanisms for inflicting bites or stings.
They feed mainly on plant and decomposed matter, which makes them players in natural recycling and the decomposition of organic matter.

Are black slugs harmful to your garden?
Although the black slug is not venomous, it can be problematic for gardeners because it readily attacks plants and crops. It feeds in particular on young shoots and tender leaves, which can slow down the growth of certain plantations and affect their development, especially in spring when conditions are favorable (humid weather and mild temperatures).
To avoid slug infestations without resorting to chemicals, several natural techniques exist:
- Use of physical barriers : Crushed eggshells, sand or crushed seashells create abrasive surfaces that are not appreciated by slugs.
- Installation of beer traps : The smell attracts slugs which fall into the trap.
- Protection of vulnerable plants : Installing nets or bells can protect young shoots from nocturnal attacks by slugs.
How to avoid black slug damage?
Dense, moist gardens, with shaded areas and a high presence of organic matter, are ideal for slugs. Well-drained soil and crop rotation practices are essential measures to reduce their presence. Ecological management also consists of encouraging the presence of natural predators, such as hedgehogs or ground beetles, insects which consume slugs.

A useful creature for the ecosystem
Although it is often undesirable in a garden, the black slug has its role in ecological balance. Its contribution to the recycling of organic matter enriches the soil and promotes the development of useful micro-organisms. It is therefore, despite its annoying aspects, an indirect ally for soil fertility and the nutrient cycle.
