Rove Beetles are of the family Staphylinidae and are, in general, predaceous beetles. Both larvae and adults are generalists and prey on anything from mites to other beetles. There are over 3,000 species listed in North America. Adults will range from 3mm up to 30mm. To keep populations viable, reduced tillage of the soil is necessary and also avoiding the use of soil insecticides. Keeping natural overwintering areas, such as mulch piles or leaf litter is essential.
