How to Make Cobwebs

Updated February 21, 2017

To create spooky scenes for your Halloween decor, party or haunted house, put plenty of cobwebs in low-lit areas. Fake cobwebs are the perfect finishing touch for giving your guests the creeps. You can make your own cobwebs with a hot glue gun and an air compressor. The compressed air jetting out by the hot glue gun makes the glue string out. When the strings touch something, they stick like a spider's web.

Place the cardboard box on the floor with the top open. This is your test area.

Attach a long extension cord to the hot glue gun so that it reaches anywhere you work. Turn on the hot glue gun and let it heat.

Put on safety glasses and gloves. Hold the sprayer head on the air compressor close to the tip of the hot glue gun where the glue comes out of the hot glue gun.

Aim the air compressor tip and hot glue gun at the opening on the cardboard box. Press the trigger on the sprayer head and squeeze the trigger on the hot glue gun.

Adjust the air pressure coming out of the compressor by moving the sprayer head closer or farther away from the hot glue gun.

Test spray in the box several times before spraying the area you want covered in cobwebs.


Use a battery powered cordless hot glue gun so the cord isn't in your way. Substitute a can of compressed air for an air compressor, if necessary. The webs spray a shorter distance and the web isn't as fine.
