Norway Rat in Tsawwassen Heights.

Why norway rat pressure is specific to Tsawwassen Heights

Tsawwassen Heights has the lowest baseline Norway rat pressure of our Tsawwassen sub-areas because most homes here were built post-1990 with modern envelope detailing — vapour barriers continuous through crawlspaces, factory-installed vent caps, and steel-clad crawlspace doors. That said, the western edge against Tsawwassen Lands ALR farmland produces wild rat populations that migrate annually, and the area's townhouse complexes (along 56 Street and 1st Avenue) share utility chases that allow rats to move between units once one is compromised. Garages with worn weatherstripping at the bottom of overhead doors are the most common failure point in this neighbourhood.

What to do right now

If you're in a Tsawwassen Heights townhouse and a neighbour has rats, treat your unit as exposed — shared utility chases mean transmission is a matter of weeks, not months. Book a perimeter inspection.
