Box Elder Bug Problem
Each fall we seem to attract box elder bugs around our clerestory windows. And, although we don't know how, some even manage to get inside. Less than two years ago we installed all new energy efficient windows and recaulked everything. Is there anything we can do to prevent them from flocking to our windows?
