December 8, 2014


  • About 1/2 inch long
  • Bright red or black in color
  • Narrow reddish lines on their back
  • Reproduce year-round in warm areas – your home!

Where Found

  • Much of the United States.


  • Enter homes in the fall, seeking winter shelter
  • Like protected areas, often in wall voids or in attics
  • Come out in the spring to find host trees to feed and lay eggs


  • Suck juices from boxelder tree
  • Not unusual to find them feeding on other plants as well


  • Cause no major damage inside homes; droppings stain curtains and other resting sites
  • Do not bite; piercing, sucking mouthparts may penetrate skin and cause a little irritation
  • Emit a foul odor when crushed
