Pavement Ant in Tsawwassen Heights.

Why pavement ant pressure is specific to Tsawwassen Heights

Tsawwassen Heights pavement-ant pressure is meaningfully lower than Beach Grove or Sunshine Hills because the housing-stock-era hardscape (1990s-2010s) is generally still intact — concrete cracks haven't yet developed the voids established colonies need, and modern paver installations often use polymeric sand that resists colony excavation. Where pressure does occur, it's almost always in townhouse strata complexes with shared paver walkways, parking-stall dividers, and landscape edging that have aged 15-25 years. Single-family detached homes here mostly see only seasonal surface activity rather than established interior infestations.

If your Tsawwassen Heights townhouse strata has visible ant mounds or units are reporting interior trails, request a strata-level inspection — single-unit treatment without addressing shared hardscape produces predictable recurrence.
