Deroceras reticulatum can transfer Escherichia coli on its body surface.

Deroceras reticulatum is a serious pest of agricultural crops, garden cultivations and horticulture.

Deroceras reticulatum is a worldwide distributed slug pest.

Deroceras reticulatum is almost exclusively restricted to cultivated areas, usually in open habitats, in meadows, near roadsides, in ruins, gardens and parks, not inside forests.

Similarly, the nematode parasite Phasmarhabditis hermaphrodita has been proposed as a biological control for the grey garden slug, Deroceras reticulatum.

The lipopolysaccharide, that is an endotoxin, from Moraxella osloensis is a molluscicide for Deroceras reticulatum when applied by injection.

Carabus nemoralis is a beneficial predator as it eats the agricultural pest Deroceras reticulatum/gray garden/milky slug, in its young stage and also its eggs.

It is a lethal parasite of the slug, Deroceras reticulatum and a large number of other slug species from the families Milacidae, Limacidae and Arionidae.

In nature, Phasmarhabditis hermaphrodita vectors Moraxella osloensis into the shell cavity of the slug host Deroceras reticulatum in which the bacteria multiply and kill the slug.

Several species in this genus are recognised as pests to agriculture and horticulture: Deroceras reticulatum, Deroceras invadens, Deroceras agreste, and Deroceras laeve.

Externally Deroceras juranum is indistinguishable from many other Deroceras, such as Deroceras praecox, Deroceras rodnae, Deroceras turcicum and Deroceras reticulatum.

This bacterium has been identified as one of the natural symbionts of a bacteria-feeding nematode, Phasmarhabditis hermaphrodita (Rhabditida: Rhabditidae), which is an endoparasite of slugs, including the slug Deroceras reticulatum (grey garden slug) which is one of the most serious agricultural and garden slug pests.
