WStratiolaelaps scimitus is a small (0.5 mm) light brown mite that lives in the top ½ in layer of soil. As a natural predator of fungus gnat pupae and of the snail parasite Riccardoella aspersa it is used by gardeners and snail breeders for biological pest control. Stratiolaelaps scimitus is also commonly used by reptile, amphibian and invertebrate keepers as a preventative or reactive measure against grain mites and reptile mites. Whereas most mite treatments are based on synthetic chemicals, predatory mites are used as a biological method of preventing and curing mite infestations.
