Natural Habitat

Stink bugs are found in a wide variety of habitats, including agricultural fields, orchards, gardens, and woodlands. They often seek shelter indoors in homes and other structures during cooler weather.

Diet & Feeding

Polyphagous, feeding on a wide range of host plants including fruits (e.g., apples, peaches, berries), vegetables (e.g., corn, tomatoes, peppers, beans), and ornamental plants. They feed by piercing plant tissues with their mouthparts and sucking out plant juices.

Behavior Patterns

Known for their ability to emit a foul-smelling liquid when disturbed or crushed, which serves as a defense mechanism. They are attracted to light and are often seen congregating on the sunny sides of buildings. In autumn, adults seek overwintering sites, often entering homes and other man-made structures.

Risks & Benefits

Potential risks include being an agricultural pest, causing significant damage to crops, leading to economic losses. They are generally not harmful to humans or pets, though their defensive stink can be unpleasant. They are not known to bite or carry diseases. There are no significant benefits associated with their presence, especially not in a home environment.
