“Across both Edmonton and Calgary, orb-weaver spiders are a common sight on exterior walls, fences, and outdoor lights. These spiders aren’t harmful—they actually play a key role in reducing flying pests like flies, gnats, and mosquitoes.
Their web design is incredibly effective. Once an insect gets caught, the spider quickly wraps it in silk, preventing it from escaping and lowering overall pest activity around the home.
However, if you start seeing multiple webs near doors, windows, and high-use outdoor areas, that usually means the surrounding insect population has increased. Addressing those underlying pests is the most reliable way to keep spider activity and web buildup under control in both cities.
Edmonton or Calgary—managing insects at the source always creates a cleaner, safer, and more comfortable home environment.”
