7. Giant Spider Invasion of the Arachnid Queen

For a high-impact, thrilling display that can be seen from down the street, transform the entire exterior of your home into a breeding ground for giant arachnids. Use hundreds of yards of white beef netting—which mimics realistic, stretchy spiderwebs far better than the cheap cotton variety—to drape over your roof, windows, bushes, and trees. Position a massive, eight-foot-tall poseable spider prop directly on your roofline or climbing down the front siding of your house. Scatter dozens of smaller, realistic plastic spiders crawling up the walls and across the lawn. To add a truly creepy narrative element, hang several life-sized, web-wrapped “cocoon victims” (made from mannequin parts or stuffed clothing wrapped in plastic wrap and spiderwebs) from your porch ceiling or tree branches.
