Why silverfish pressure is specific to Beach Grove
Beach Grove silverfish pressure is heavy. Coastal humidity provides constant background conditions favourable to silverfish (relative humidity rarely drops below 60% even in summer, often 75%+ in winter). 1960s-70s cottage housing stock has substantial original-era basement detailing that traps moisture: original concrete floors, unsealed crawlspaces, aging plumbing with multiple slow leaks. Beach-equipment storage areas accumulate humid conditions year-round. Stored-paper and seasonal-storage habits compound. Vacation-rental owners discover heavy silverfish presence during off-season cottage opening — silverfish thrive in unoccupied, unheated, humid spaces. Treatment requires aggressive humidity reduction in addition to chemical control because the underlying coastal-climate baseline can't be eliminated.
