The same steps used to air seal a home and minimize moisture damage also help prevent pest intrusion. Bug-resistant home sealing includes measures such as caulking and sealing all seams and holes in the foundation, walls, and roof, flashing the sill plate to help block and expose termite migration, and using finishing materials pests can’t eat such as cement-fiber cladding, stone, or brick. Non-vented crawlspaces and attics provide fewer potential entry points than their vented counterparts.
