Boxelder Bugs

Boxelder bugs (Boisea trivittata) are common insects found throughout North America, easily recognized by their black bodies and distinctive orange or red markings. These bugs primarily feed on the seeds and leaves of boxelder trees, as well as other maples and ash trees. While they are harmless to humans and do not cause damage to structures, they can become a nuisance when they seek shelter indoors during the fall and winter months.

Key Characteristics:

  • Black bodies with orange or red markings
  • Primarily feed on boxelder, maple, and ash trees
  • Harmless to humans and do not damage structures

Management Tips:

  • Seal entry points to prevent indoor invasions
  • Remove boxelder trees or plant non-attractive alternatives
  • Use gentle removal methods if they invade your home

History of Boxelder Bugs

Boxelder bugs (Boisea trivittata) have been a part of North American ecosystems for centuries, primarily associated with boxelder and maple trees. These insects are indigenous to the United States and Canada, thriving in areas with abundant deciduous trees. Their populations tend to increase in the fall as they seek warmth, leading them to invade homes and buildings. Over time, boxelder bugs have adapted to urban environments, making them a common nuisance in residential areas.

Key Historical Points:

  • Indigenous to North America, particularly in regions with boxelder and maple trees
  • Populations rise in the fall as they seek shelter from cold weather
  • Adapted well to urban environments, increasing their encounters with humans

Additional Facts:

  • First described scientifically in the 18th century
  • Their presence is more pronounced in areas with abundant host trees
  • Not considered agricultural pests, but can be a nuisance in homes during the colder months
