The first thing we did, other than cleaning up all the dead bugs that had accumulated over the 2-3 years the house was empty (ew!) was to replace the front door. Even though the door that was there was actually in decent shape, it was about 2" too small for the frame all the way around, and the big gap at the bottom is the main reason there were so many bugs. (We're really lucky, honestly, that we didn't get rodents or a snake. I guess since there was no food or water, there was nothing to really attract them.)
