Boxelder bugs are a true bug that have evolved to rely on boxelder trees for their primary source of food and shelter. Since boxelder nymphs rely on seed pods from female boxelder trees for food, these trees are critical to the ongoing reproduction cycle of boxelder bugs.
This makes boxelder trees the largest attractant for boxelder bugs, outside of a few other critical things they look for: mates and covered habitats that protect them from cold and predators. Boxelder bugs prefer to stay warm, so they sun themselves on tree surfaces during the day and return to hiding places under bark at night.
What Attracts Boxelder Bugs
