Common name: Boxelder bugs
Scientific name: Boisea trivittata
Hosts: Boxelder bug’s primary host is boxelder (Acer negundo), but it can also be found on silver maple (Acer saccharinum) and trident maple (Acer buergerianum).
While boxelder bug can cause minor damage to its preferred host plant, the boxelder tree (Acer negundo), it is primarily a nuisance for the homeowner. The insect overwinters as adults, who must find warm, protected sites. Boxelder bugs will seek access to warm buildings through any cracks or crevices in foundations, doors, and windows, and it is their presence indoors that poses a nuisance. Boxelder bugs are found throughout the United States.
