16 Scary Halloween Decorations With Trash Bags, From Giant Spiders to Ghost Lanterns

You can turn a box of black trash bags into a haunted house for a few dollars, as long as you keep the plastic away from heat and the cords dry.

Trash bags are the cheapest Halloween decor you can buy. Cut black bags into streamers, stuff them for spiders, or shape them into ghosts and curtains. Most projects take under an hour and need only tape, scissors and a filler.

Dry leaves and old newspaper work well, so you rarely need to buy anything else.

Keep the plastic away from anything hot or live, since thin film melts and burns fast. The Consumer Product Safety Commission says to use flameless candles outside and to clear porches and steps of obstacles. Iowa State Extension says to plug outdoor lights into GFCI outlets and use cords rated for outdoor use.

This guide gives 16 ideas sorted by where they go, with the steps, a pairing, a watch-out and our verdict on each. It also covers tools, wind, safety and cost tiers.

What Is Wrong With a Plain List of Trash Bag Decorations?

Most lists show 25 photos with no steps. They don’t say which bag to buy, what to stuff inside or how to keep it up in the wind.

We kept the best ideas and added the how-to. Each one has a short build, a risk to avoid and our honest verdict. Then we added the tool list and the safety rules.

What Do You Need to Start?

You need fewer supplies than you think. Most of them are in a kitchen drawer or a garage.

Supply	Use it for	Notes
Black trash bags	Streamers, curtains, spiders	Thicker bags tear less
Orange leaf bags	Pumpkins and faces	Fill with leaves or paper
White or clear bags	Ghosts and mummies	Show a light behind them
Packing tape or duct tape	Seams and legs	Use painter’s tape on walls
Newspaper or old leaves	Stuffing	Dry only, keep it away from heat
Battery lights	Glow inside ghosts and lanterns	Never use a bulb that gets hot

Our rule: buy the bags and the tape first. Everything else you can find at home.

Ghost and Creature Ideas

1. A Hanging Trash Bag Ghost

Stuff a white bag with crumpled paper to make a head. Tie a string under the “chin” and fan out the bottom into a skirt. Cut two eyes from black bag scraps and tape them on.

Pair with: a tree branch or a porch hook.

But watch out: a loose ghost twists and tears. Tie it to a sturdy hook, and snip the bottom into strips so wind passes through.

Our take: our top pick for a first project. It takes ten minutes and looks great in a row.

2. A Floating Ghost Lantern

Cut a clear or white bag into a long sheet and drape it over a balloon or a wire frame. Put a battery tea light inside. Hang it from a branch so it glows.

Pair with: a dark yard and a few more lanterns.

Watch out: plastic and heat don’t mix. Use a battery light, not a bulb or a candle.

Our take: the prettiest idea on this list. A cluster of five glows like spirits at dusk.

3. A Trash Bag Mummy

Wrap a mannequin form, a chair or a post in strips of white bag. Overlap the strips and tape the ends. Leave a gap for two glowing eyes.

Pair with: a gray bag cloak for a zombie look.

But watch out: loose strips snag in wind. Tape the ends down and keep the pieces short.

Our take: a good pick for a front door. It looks messy on purpose, so mistakes don’t show.

4. A Trash Bag Witch

Cut a black bag into a long robe. Stuff the head with paper and add a pointed hat from a bag and a cardboard cone. Tie a broom in one hand.

Pair with: a stuffed boot or a cauldron at the feet.

Watch out: a tall figure needs a base. Lean it against a wall or tie it to a post.

Our take: easy and funny. A witch in a bag cloak looks better than you would expect.

Spider and Web Ideas

5. A Giant Yard Spider

Stuff two black bags, one large for the body and one small for the head. Make eight legs from rolled bags filled with newspaper or pool noodles. Tape the legs to the body and bend them in the middle.

Pair with: a web over a shrub.

But watch out: giant legs catch the wind. Stake the body to the ground, and keep it out of the path.

Our take: our favorite yard piece. It’s big, cheap and scary from the street.

6. A Stretched Trash Bag Web

Cut a black bag into a long strip, then cut tiny slits along each edge. Pull the strip until it stretches into a web. Drape it over a bush, a railing or a doorway.

Pair with: small plastic spiders.

Watch out: stretched plastic is thin and tears. Handle it gently, and expect a short lifespan in wind.

Our take: a fast, cheap web for any corner. It has a better look than store-bought stretch webs.

7. A Balloon Spider

Blow up a black balloon for the body. Cover it with a bag, and tie it off. Add eight legs cut from bags, twisted into spirals.

Pair with: a thin string to hang it.

But watch out: balloons pop in the sun and wind. Use it indoors or in a covered porch.

Our take: a fun hanging piece for a party. It floats with a gentle draft.

Window and Wall Ideas

8. Window Silhouettes

Cut a shape from a black bag, like a cat, a bat or a witch. Tape it to the glass. A lit room behind it makes the shape pop.

Pair with: a string of orange lights.

Watch out: tape can pull off paint. Use painter’s tape on the glass.

Our take: a nice treat for an apartment. It adds spook without any nails. For more ideas, see our Halloween window decorations.

9. A Curtain of Doom

Cut black bags into long fringes, leaving the top connected. Tape the top edge to a doorframe. Walk through the strips for a creepy entrance.

Pair with: a fan for a gentle breeze.

But watch out: guests can trip on loose strips. Cut them above the floor and keep them clear of shoes.

Our take: our best party entrance. It’s easy, and everyone wants to walk through.

10. A Wall Drape

Cut bags into wide sheets and tape them across a wall in loose swags. Overlap the edges and leave a gap. Pin a few paper bats on top.

Pair with: purple lights.

Watch out: tape pulls off paint. Test a small spot first.

Our take: a quick way to cover a plain wall for a photo spot. It looks dramatic in a dim room.

11. A Haunted Hallway

Line a hallway with bag streamers and loose webs. Add a few ghosts and a dim light. Tape the ends of everything at the ceiling.

Pair with: spooky music.

But watch out: a dark hallway is a trip risk. Keep the floor clear and the path wide.

Our take: the best use of a boring hall. A dim light and a few bags set the mood.

Yard and Entrance Ideas

12. A Leaf Bag Pumpkin

Fill an orange leaf bag with dry leaves, and tie the top with a green ribbon. Cut black felt or a bag into a face. Tape it to the front.

Pair with: a real pumpkin beside it.

Watch out: wet leaves rot. Use dry leaves, and move the bag if rain is coming.

Our take: a classic. It uses leaves you already raked.

13. A Trash Bag Tombstone

Cut a tombstone shape from foam board or cardboard. Wrap it in a gray bag and tape the back. Paint or tape on the letters.

Pair with: a patch of mulch and a skeleton hand.

But watch out: cardboard soaks up rain. Seal it, or bring it in on wet nights. For more ideas, see our DIY Halloween yard decorations.

Our take: cheap and sturdy for a dry week. Build five to make a graveyard.

14. A Stuffed Bag Scarecrow

Stuff a pair of old pants and a shirt with bags of leaves. Use an orange bag for the head and draw a face. Stake it to a chair.

Pair with: a straw hat and a hay bale.

Watch out: a heavy scarecrow can tip. Tie it to a post or a fence.

Our take: a family favorite. It’s a great use for last year’s leaf bags.

15. A Spooky Door Garland

Cut black bags into long strips. Braid or twist three strips together to make a rope. Tape the rope around the door and add a few paper bats.

Pair with: a wreath made of stretched bag strips.

But watch out: tape on paint can peel it. Use painter’s tape, and remove it the same week.

Our take: a quick fix for a plain door. The twisted plastic looks like thick rope.

16. A Body Bag Prop

Fill a large bag with crumpled paper and tie it to look like a figure on the ground. Put it in the yard or the porch, away from the street. Add a hand or a boot at one end.

Pair with: a warning sign for trick-or-treaters.

Watch out: a realistic prop can scare kids or worry neighbors. Keep it on your property and well away from the road.

Our take: only for adult parties and tall yards. If you have little visitors, skip it.

How Do You Keep Trash Bag Decor Safe?

Plastic melts and burns, and cords are a hazard. Keep bags away from hot bulbs, candles, stoves and heaters. Use battery or LED lights inside ghosts and lanterns.

Use only outdoor-rated cords and lights, and plug them into a GFCI outlet. Tuck cords out of walkways and keep them out of water. Turn lights off when you leave or go to bed.

Our rule: if a bulb feels warm, don’t put plastic near it. Keep bags and finished props away from small children.

How Do You Keep Decor Up in the Wind and Rain?

Plastic catches wind, so fix every piece twice. Use string, stakes and tape, not just one. Cut the bottoms of hanging pieces into strips so air passes through.

Bring paper and cardboard items inside on wet nights. Check your display each evening and fix tears with tape. Ghosts made of thick bags last longer than thin ones.

What Do You Do With the Bags After Halloween?

Don’t throw away everything. Fold clean bags and reuse them next year. Save leaf-filled bags for the compost pile.

Torn plastic film usually can’t go in curbside recycling. Check with a store drop-off or your local program to see what they accept. Our reusing pumpkins as compost guide covers the rest of the leftovers.

What Is a Weekend Plan?

Do the quick ones first and the bulky ones last.

Plan:

1. Buy bags, tape and lights.
2. Make the ghosts and the pumpkins.
3. Build the spider and the web.
4. Hang the curtain, the drapes and the garland.
5. Stake the yard pieces and test the lights at dusk.

What Will It Cost, and How Long Will It Take?

Prices vary by store and region, so use these tiers.

Tier	What it covers	Typical time
Free to cheap	Ghosts, webs, silhouettes, garland	An afternoon
One weekend	Giant spider, mummy, curtain, scarecrow	1 to 2 days
Bigger project	A full haunted hallway and yard	A few weekends

Start with the cheap tier. Add the big pieces if you love the look.

Common Mistakes to Avoid

Putting plastic near a bulb. Heat can melt it. Use battery lights.

Skipping the stakes. Wind will carry a light bag away.

Using wet leaves. They rot and smell.

Taping on fresh paint. Use painter’s tape.

Leaving cords in walkways. Tuck them away, and plug into a GFCI outlet.
