Use weatherstripping to keep bugs from getting in around the sides and top of the frame. If there's a gap at the bottom of the door, install a steel or aluminum threshold at the bottom, along with a door sweep on the lower edge of the door. If there are gaps between the doorframe and the wall, seal them with caulk.
