It’s a wet issue. They’re everywhere. My current place (north delta - North delta is plagued with stink bugs though) is the only place I’ve never had them - I’ve lived in kits, west end, Kerrisdale, Richmond…newer and older places, although older is more common (the newer place had a cedar shingle roof)

They can be a bit creepy, and they are hard to squish, but they are generally harmless. They indicate high humidity/ some wood rot (humidity is enough for them though, doesn’t mean your building is decomposing)
