Value in Pest Management

These non-native beetles are generalist predators, feeding on a variety of small arthropods in a variety of cropping systems. They clearly contribute to pest management. However, they are also pests of homes where they can aggregate in large numbers through the winter. They have also been implicated in the decline of native ladybeetles. They are sold commercially (see BIRC online Directory).
