1. Seal up Cracks and Gaps
Bugs and rodents are looking for every opportunity to get into your home—so don’t give them one. Cracks, holes, gaps, and open doors and windows are exactly the invitations unwelcome guests are looking for to set up camp. You can use caulk, expandable foam, copper mesh, and even liquid cement to seal up holes and gaps around pipes, outlets, air condition units, and dryer vents. For larger cracks in the foundation, it is probably best to consult a professional, as this may be a serious structural issue.
