Box Elder Bug Biology and Seasonal Behavior

Box elder bugs (Boisea trivittata) spend summer feeding on the seeds of box elder trees, maple trees, and ash trees. As fall temperatures drop, adults seek warm structures for overwintering. They aggregate in enormous numbers — sometimes thousands — on sun-warmed exterior walls before entering through tiny gaps. Once inside wall voids and attic spaces, they enter diapause (dormancy). On warm winter days, some become active and wander indoors, appearing at windows and on walls. They become active again in spring, moving outdoors to reproduce. The most effective control strategy is fall exclusion before they enter.
