They're not after you — they're after the insects. Your eaves are prime real estate.
Arizona is home to black widows and desert recluses alongside harmless house spiders. They build webs in eaves, window frames, garages, and sheds — wherever insects gather.
Spiders climb to reach those spots: up foundation walls, across stucco, straight to the windows and doors.
Deny them the climbing routes. The film band takes away the walls spiders use to reach windows, doors, and eaves — no climb, no web, no spiders waiting by the front door.
