19. Creepy Crawly Tree Trunk
Turn a mature, thick-trunked tree in your garden into a source of skin-crawling terror with a mass migration of giant insects. Source dozens of oversized, realistic plastic spiders, beetles, or centipedes. Mount them closely together climbing up the trunk of the tree in a swirling, organized column, as if they are swarming out of a hole in the roots and heading straight for the canopy.
This decoration is incredibly effective because it plays on natural fears and utilizes the existing texture of the tree bark to create a realistic, unsettling effect. Use a strong, focused spotlight at the base of the tree to cast sharp, dramatic shadows of the climbing insects upward, making the swarm look even larger and more active than it is. It is a simple, high-impact design that is guaranteed to make passersby do a double-take.
