A properly insulated and encapsulated crawlspace in Langley BC also reduces pest entry risk — and for good reason. The warmth gradient between an uninsulated crawlspace and the cold ground outside creates exactly the conditions that attract rodents and insects looking for a sheltered environment. Sealing the crawlspace with spray foam on walls, a vapour barrier on the floor, and properly sealed access panels eliminates both the warmth gradient and the entry gaps that pests exploit. Western Insulation's crawlspace system approach in Langley addresses pest risk as a byproduct of proper insulation. Book at westerninsulation.ca/basement-and-crawlspace-insulation/
