Diet & Feeding

Behavior Patterns

Active in cool temperatures (spring/autumn), they often migrate into homes in large numbers. If crushed, they leave a distinct reddish-brown stain due to their body pigmentation.

Risks & Benefits

They are considered nuisance pests rather than biological risks; they do not bite humans or pets and do not transmit disease. They can damage indoor fabrics if crushed, leaving permanent stains.
