Silverfish in Tsawwassen Heights.

Why silverfish pressure is specific to Tsawwassen Heights

Tsawwassen Heights silverfish pressure is the lowest of our Tsawwassen sub-areas. Modern construction practices (continuous vapour barriers, proper basement ventilation, sealed crawlspace detailing, factory-installed bathroom fans) eliminate most of the persistent humidity silverfish need. Where pressure does exist, it's almost always traceable to specific failure points: bathroom fan that has stopped working (allowing humidity buildup), plumbing leak at a fixture connection (creating localised moisture), or basement-suite construction with inadequate ventilation. Treatment in these scenarios resolves the issue once the underlying failure is corrected.
