Common House Spider in Tsawwassen Heights.

Why common house spider pressure is specific to Tsawwassen Heights

Tsawwassen Heights house-spider pressure is the lowest of our Tsawwassen sub-areas. Newer landscape installations have less mature garden density (fewer overgrown corners, less established mulch beds, smaller backyard tree canopy). Modern construction reduces small-crack harbourage in exterior architectural details. Townhouse strata complexes have more limited garden space than detached homes. Where pressure does exist, it concentrates around mature backyard plantings (homes that have been occupied 15-20+ years and developed mature gardens) and shared-landscape areas of townhouse stratas. Fall-season visibility is the dominant pattern.
