Catching a leprechaun on St. Patrick’s Day is one of those childhood traditions that feels like pure magic. Kids spend the afternoon building a trap from shoeboxes and pipe cleaners, set it out before bed, and wake up to tiny footprints, a flipped-over trap, and a note from a very cheeky visitor. It costs almost nothing and creates a core memory.
If you have never made one before, start simple. The best leprechaun traps for beginners use things you already own — a cardboard box, a hat, a jar — plus one irresistible lure: something shiny, something gold, or something rainbow-colored. Leprechauns in the stories are famously greedy, vain, and a little too confident, which is exactly why every trap below works.
This list is built for total beginners. The first section has eight traps you can finish in under 30 minutes with zero crafting experience. From there you can move on to box traps, household-object traps, rainbow designs, lures and overnight magic, and a few ambitious builds for kids who want a real project. Pick one, gather your supplies, and get started — the leprechaun will not wait.
Start Here: The 8 Easiest No-Fail Traps
These need almost no skill, no special tools, and very little time. If this is your first leprechaun trap, begin here.
1. The Classic Shoebox Drop. Cover a shoebox in green paper, prop one end up with a stick, and scatter gold coins underneath. When the leprechaun goes for the gold, the box drops. It is the original, and it still works.
2. The Upside-Down Top Hat. Flip a green party hat upside down, line the inside with chocolate coins, and hide the opening with tissue paper. The tissue gives way when he steps in.
3. The Cereal Box Slide. Cut one long side out of a cereal box, decorate the outside with rainbows and shamrocks, and lean it like a ramp. A tiny ladder of pretzel sticks leads up to the top, where a pile of coins waits.
4. The Mason Jar Honeypot. Fill a jar with Lucky Charms cereal or gold wrapped candy, tie a green ribbon around it, and tape a small sign that says “Free Gold.” Leprechauns climb in for the treasure and can not climb out.
5. The Paper Plate Pit. Cut a hole in the middle of a paper plate, cover the hole loosely with green tissue paper, and decorate around it. Coins piled in the center draw him onto the fragile tissue.
6. The Laundry Basket Pitfall. Lay a green towel over an empty laundry basket so it sags in the middle, then ring it with shiny coins. It looks solid from the side, but there is no way back up.
7. The Book Bridge. Stand two stacks of books apart and lay a strip of cardboard between them like a bridge, with coins in the middle. Underneath, place a box lined with a soft towel for the fall.
8. The Paper Bag Ambush. Decorate a paper lunch bag with rainbows, fold the top into a loose funnel, and put coins inside. Once he slides in after the gold, the narrow opening traps him.
Box Traps Anyone Can Build
Boxes are the backbone of leprechaun trapping. Cardboard is free, light, and easy to decorate, and every box trap follows the same logic: bait inside, collapse the walls.
9. The Prop-and-String Classic. Decorate a box, prop it open with a pencil tied to a string, and run the string to the bed. In the morning, let the kids “find” the trap already triggered with tiny footprints around it.
10. The Rainbow Road Box. Lay a strip of rainbow-striped paper as a path leading straight under a propped-up green box. Place a pot of coins at the very end, because a leprechaun simply can not walk past a rainbow without following it.
11. The Tissue Trap Door. Cut a hole in the top of a box, stretch tissue paper over it, and camouflage the tissue with green paper grass. A ladder of craft sticks leads up to a coin pile sitting right over the hidden door.
12. The Leprechaun Garden. Fill a shallow box with soil or green tissue “grass,” add a toy-sized ladder and a little house, and place coins on the doorstep. The box looks like a cozy home but the doorway is a one-way trip.
13. The Aluminum Foil Fort. Wrap a shoebox in shiny aluminum foil so it glints and gleams. Leprechauns love shiny things, and the bright wrapping makes this trap double as a decoration.
14. The Split-Level Duplex. Tape two boxes together, one with bait on top and one empty below, connected by a hole the tissue-paper trap door covers. If he escapes the top floor, he drops to the ground floor.
15. The Sliding Lid Box. Use a box with a lid that slides rather than lifts. Balance the lid half-open with bait beneath it; the weight of the leprechaun tips the lid shut.
Hat, Jar and Household-Object Traps
Look around the house and you will find trap parts everywhere. These designs start from objects you already own.
16. The Leprechaun Top Hat Tower. Build a cone from green poster board, decorate it with a gold buckle band, and hide coins under the brim. Add a ladder made from green paper straws so he can climb to the very top.
17. The Flower Pot Trap. Fill a small flower pot with soil and real or fake clover, then press chocolate coins into the dirt like buried treasure. Cover the opening with a paper doily that tears when stepped on.
18. The Umbrella Net. Open an umbrella and lay it upside down on the floor, baited with coins. He climbs the handle, drops in for the gold, and can not climb the slippery nylon walls.
19. The Sock Slide. Stretch a long sock into a tunnel, bait the far end with a shiny coin, and place it over a bowl. The sock stretches as he crawls through and drops him into the bowl.
20. The Teacup Well. Set a large mug or teacup on its side with coins inside and a green straw ladder leading up. Once he is inside chasing gold, tip the cup upright in the morning — or just let the kids find him “stuck.”
21. The Birdhouse Bait. Paint a small wooden birdhouse in rainbow colors, glue a cardstock rainbow to the roof, and surround it with chocolate coins. The roof opens to a surprise: a cotton-ball “cloud” that hides the drop.
22. The Pillow Fort Pit. Build a small fort with a hollow center, bait it with candy, and line the floor with a loose towel. He walks in over the towel and tumbles into the hollow middle.
Rainbow-Themed Traps
Rainbows are the leprechaun’s greatest weakness. In every story, the pot of gold waits at the rainbow’s end, so a rainbow lure is practically cheating.
23. The Cotton Ball Rainbow Bridge. Arch pipe cleaners in rainbow colors between two boxes with cotton ball “clouds” at each end, and put the coin pot at one cloud. He will march straight across the bridge and into the box.
24. The Paper Chain Rainbow. Make a paper chain in rainbow colors leading from the window to the trap. It takes ten minutes, looks festive, and tells the leprechaun exactly where to go.
25. The Rainbow Staircase. Stack books and cover them with strips of colored paper in rainbow order, ending at the mouth of an open box. Painted-on gold arrows make the path impossible to resist.
26. The Crayon Box Rainbow. Stand crayons upright in rainbow order to form a glowing path of color leading into a trap. It doubles as a colorful classroom display before the big night.
27. The Fruit Loop Trail. String rainbow-colored cereal on yarn and lay the garland from the hallway to the trap, with a few loose pieces as a crumb trail. Even if the leprechaun escapes, he leaves a delicious clue.
Lures, Bait and Overnight Magic
The trap only matters if the leprechaun visits — and the visit only matters if there is evidence in the morning. These ideas make the magic real.
28. The Green Milk Prank. Add a drop of green food coloring to the milk in the fridge overnight. The leprechaun was thirsty, and now the kids have proof he came.
29. The Tiny Footprint Trail. Dip a fork or a tiny toy shoe in green washable paint and stamp footprints from the window to the trap. In the morning, the evidence is everywhere.
30. The “Caught You” Note. Leave a tiny handwritten note from the leprechaun inside the sprung trap, apologizing for the mess or promising to return. Kids treasure these notes for years.
31. The Gold Coin Confetti. Scatter chocolate coins around the trap with a few bite marks in one. He grabbed the gold and ran — but he could not carry it all.
32. The Glitter Mischief. Sprinkle green glitter on the table where the trap sat. Leprechauns shed magic wherever they go, and glitter is the proof.
Next-Level Traps for Ambitious Builders
Ready for a bigger project? These take longer and use a few more supplies, but they are the ones kids talk about at school.
33. The Pulley Lift Trap. Build a small platform on string that hoists a leprechaun-sized basket when a bait string is pulled. It introduces real simple-machine science into the craft.
34. The LEGO Fortress. Construct walls, a gate, and a rainbow staircase from LEGO bricks with a hidden chamber in the middle. Sturdy, reusable, and endlessly rebuildable for next year.
35. The Rube Goldberg Gauntlet. Chain together dominoes, ramps, and levers so that grabbing the coin sets off a series of steps ending in a net dropping over the thief. Film it — the video is half the fun.
Tips for a Successful Leprechaun Trap Night
- Set the trap the night before St. Patrick’s Day. The magic happens overnight, so have everything in place before bedtime on March 16th.
- Let kids do the decorating. The trap does not need to look perfect — a trap a child decorated themselves is the one they believe in.
- Keep bait edible and safe. Chocolate coins and cereal are perfect. Skip anything small enough to be a choking hazard for toddlers.
- Plan the “evidence” in advance. Decide tonight what the morning will look like: a sprung trap, footprints, a note, or glitter. Buy or make those props now.
- Use washable materials for footprints. Green washable paint or food coloring washes out of carpets and clothes; permanent markers do not.
- Match the build to the child’s age. Toddlers do best with decorating a pre-built box, while older kids can handle cutting, gluing, and engineering.
- Keep it light for school projects. If the trap travels to school, build small and sturdy — big elaborate traps rarely survive the bus ride.
- Channel the creativity year-round. Once your kids are hooked on building traps, put that energy into celebrations all year — our 40 birthday party ideas are a great place to start.
Frequently Asked Questions
What do you need to make a leprechaun trap?
Almost nothing. A cardboard box or hat, something green to decorate with, tape or glue, and bait like chocolate coins or cereal. Most of the traps on this list use supplies already in your home or classroom.
How do you make a leprechaun trap for kindergarten?
Keep it simple and let the kids decorate: cover a shoebox in green paper, add stickers and a “Free Gold” sign, and prop it up with a stick. The building is the activity; the “catching” is the magic part you stage overnight.
What bait works best in a leprechaun trap?
Anything gold and shiny. Chocolate coins are the classic choice, followed by gold-wrapped candy, plastic coins, and shiny trinkets. Rainbows, green glitter, and anything sparkly also draw leprechauns in the stories.
Do leprechaun traps actually catch anything?
They catch memories. The fun is in building the trap and staging the overnight “visit” with footprints, a sprung trap, or a tiny note. Kids who build traps remember the morning reveal for years.
When should you set out a leprechaun trap?
The night before St. Patrick’s Day — March 16th. Set it out before bedtime so the “visit” happens overnight, and check it first thing in the morning for maximum excitement.
Bottom Line
A leprechaun trap is never really about catching anything. It is about an afternoon at the kitchen table with glue on your fingers, a child who is absolutely certain this year will be the year, and a March morning that starts with squeals of delight. Build the simplest trap on this list or the most elaborate — what matters is that you build it together. The leprechaun may escape with the gold, but the memory is yours to keep.
