Improperly installed decorations can lead to fire hazards, injuries from trips and falls, and risks to wildlife. High winds in the fall can dislodge unsecured decorations, creating additional safety concerns. Pumpkins left outside may attract bears, while loose or low-hanging decorations like fake spiderwebs can entangle wildlife, especially during their migration to winter habitats. Open flames in jack-o-lanterns can cause fires if not monitored. These risks highlight the need for careful planning and setup of Halloween displays to ensure safety for both people and animals.
