Many of the same steps used to air seal and flash a home also help prevent pest intrusion. A pest-resistant home includes measures such as caulking and sealing of all seams and holes in the foundation, walls, and roof; properly grading the site to drain water away from the home; providing adequate space between wood and siding and the ground to help minimize pathways for infestation; flashing the sill plate to help block termite migration; using finishing materials pests can’t eat such as  cement-fiber cladding, stone, or brick; covering all vents except for the clothes dryer with insect screening to help keep out larger pests; and installing irrigation and landscaping away from foundation walls. Non-vented crawlspaces and attics provide fewer potential entry points than their vented counterparts.
