To make this massive arachnid, use 1-inch PVC pipes cut into eight 4-foot sections for the legs and two shorter 2-foot pieces for the main body frame.

You can attach glowing red LED lights for eyes and position the spider so it hangs off your roof.

Plus, create the illusion of a trapped victim using plastic wrap and old clothes, it adds just the right amount of creepy realism.

Materials Needed

• 1-inch PVC pipes (eight 4-ft and two 2-ft pieces)
• Elbow joints and T-connectors
• Black spray paint and faux fur or insulation tubing
• Large trash bag, foam, or crumpled paper
• Red LED lights or small flashlights for glowing eyes
• Plastic wrap and old clothing
• Zip ties or duct tape

Step-by-step Guide

Step 1: Assemble the PVC frame using elbows and T-connectors to form a spider shape. Adjust angles for natural leg bends.

Step 2: Wrap each leg in pipe insulation or faux fur to give it bulk and texture, then spray-paint it matte black.

Step 3: Stuff a trash bag for the spider’s body and secure it to the frame with zip ties.

Step 4: Add red LED lights to create glowing eyes that shine in the dark.

Step 5: Mount the spider on your roof, garage, or porch ledge using sturdy rope or brackets.

Step 6: For extra drama, hang a wrapped victim made from plastic wrap beneath it, just creepy enough to make trick-or-treaters jump.

Tips:

You can use lightweight materials so the spider doesn’t strain your roof structure.

If you want it to move slightly in the wind, keep the joints loose—it’ll make the illusion even eerier.
