Brown Marmorated Stink Bug

Natural Habitat

Originally from Asia, introduced to North America and Europe. Found in agricultural fields, orchards, gardens, and urban/suburban areas. They often seek shelter indoors in homes and other structures during colder months.

Diet & Feeding

Polyphagous, meaning they feed on a wide variety of plants. They are sap-sucking insects that feed on fruits, vegetables, and field crops, including apples, peaches, corn, soybeans, tomatoes, and ornamental plants.

Behavior Patterns

Known for seeking overwintering sites in homes and buildings in large numbers during autumn. When disturbed, they emit a foul-smelling liquid as a defense mechanism. They are generally slow-moving but can fly. Females lay clusters of barrel-shaped eggs on the undersides of leaves.

Risks & Benefits

Risks: Significant agricultural pest causing damage to a wide range of crops. Their presence indoors can be a nuisance, and their defensive odor is unpleasant. They do not bite or transmit diseases to humans. Benefits: No known significant benefits to humans or the ecosystem in introduced regions; primarily considered a pest.
