How to Make an Earwig Trap: Baited Container That Lures Them Away

Earwigs turned my hosta leaves into Swiss cheese overnight. 🌿 These armored pests curl up plants and chew holes in tender foliage, but a simple baited trap can lure them away before they cause real damage.

The trap works by mimicking their natural hiding spots—dark, moist containers with something sweet to attract them. You’ll need a shallow container (like a pie tin or yogurt cup), damp cardboard or paper towels, and a little apple cider vinegar or beer as bait.

Earwigs are drawn to the scent and moisture, then get trapped when they can’t climb out. By morning, you’ll find dozens of earwigs clustered inside, ready for disposal. The best part? This method is chemical-free and works in minutes.

I’ve saved entire garden beds using this same setup for years—no more shredded leaves or curled petals. For extra protection, place traps near problem areas at dusk when earwigs are most active.

Empty and reset them every few days, and you’ll see a noticeable difference in just one week of consistent trapping.

Step-by-step instructions for making an earwig trap

Here's my foolproof method that keeps earwigs out of your garden for good.

Pick a shallow container with high sides—old plastic food containers, yogurt cups, or even a shallow bucket work perfectly. The key is that it needs to be at least 3 inches deep but not so deep that earwigs can't climb out easily. I like to use containers with a diameter of 6-8 inches because they're big enough to attract earwigs but small enough to place strategically around your garden.

Make sure the container has no holes or cracks. Earwigs are small but clever—they'll find their way out of anything with an opening. If your container has drainage holes, cover them with tape or mesh so moisture stays inside but earwigs can't escape. You'll want to place this trap near problem areas like flower beds, vegetable patches, or under eaves where earwigs hide during the day.

The secret to a successful earwig trap is using the right bait. Earwigs love damp, decaying organic matter, so a simple mix of water and a few drops of beer works wonders. Fill the container about halfway with water, then add a tablespoon of beer. The beer's yeast and alcohol create an irresistible scent that lures them in.

For an even stronger trap, add a few damp newspaper strips or a small piece of cardboard soaked in water. Earwigs are attracted to moisture and the idea of shelter. Place the bait items vertically along the sides of the container so earwigs can climb in but struggle to climb out. The beer will keep them disoriented once they're inside.

Place your traps in areas where you've noticed earwig damage or where they're most active. Early morning or late evening is the best time to set them because earwigs are nocturnal and come out when it's damp. I like to position traps near the base of plants, under mulch, or along garden edges where earwigs gather to hide during the day.

Check your traps every 2-3 days and empty them if they're full. You'll know it's working when you see earwigs crawling around inside or when you find them drowned in the beer mixture. If the water evaporates, add a little more and refresh the beer to keep the scent strong. The more frequently you empty and reset the traps, the more effective they'll be at keeping your garden earwig-free.

After setting your traps, keep an eye on them for at least 2 weeks to see how effective they are. If you're still seeing earwigs in your garden, add more traps or move existing ones to different locations. Earwigs are persistent, so you might need to place traps in multiple spots around your yard.

In addition to traps, reduce earwig habitat by keeping your garden clean and dry. Remove piles of debris, mulch away from plant stems, and water plants at the base rather than overhead. Earwigs thrive in damp, dark environments, so eliminating those conditions makes your garden less appealing to them. With consistent trapping and good garden hygiene, you'll see a significant reduction in earwig activity within a few weeks.

When you empty your traps, you don't have to let the earwigs go back into your garden. Instead, dispose of them by pouring the contents down a drain or flushing them if your plumbing can handle it. If you're uncomfortable with that, simply dump the contents into a sealed bag and throw it in the trash. The key is to keep them out of your garden entirely.

Once you've removed the earwigs, give your traps a quick rinse with soapy water and refill them with fresh bait. This keeps your traps effective for longer and prevents any lingering odors from deterring new earwigs. With regular maintenance, your traps will continue to work for months, giving you a chemical-free way to protect your plants.

Tips & tricks for perfect earwig traps

These simple tricks will help you turn your basic earwig trap into an unstoppable pest control system.

Container Selection: For best results, choose containers with slightly textured sides—like yogurt cups with ridges or plastic takeout containers. The rough edges help earwigs climb in but make it harder for them to climb back out. I've found that containers with a slightly tapered shape (wider at the top) work even better because they create a natural funnel effect. Avoid completely smooth containers like glass jars—they're too slippery for earwigs to grip.

Bait Enhancement: While beer works perfectly, you can make it even more effective by adding a splash of apple cider vinegar (about 1 teaspoon per tablespoon of beer). The vinegar's acidity mimics the scent of decaying plant matter that earwigs find irresistible. If you don't have beer, a mix of water and molasses (1 tablespoon per cup of water) works almost as well. The key is to keep the scent strong and appealing—earwigs have a highly developed sense of smell.

Placement Strategy: In Step 3, when you're setting your traps, place them with the opening facing slightly downward (about 10-15 degrees). This helps prevent rain from diluting your bait while still allowing earwigs to climb in. I like to position traps near the base of plants where earwigs hide during the day, but not directly against the stems—leave about 2 inches of space so they can crawl in easily. For large gardens, consider creating a grid pattern with traps spaced about 10 feet apart.

Maintenance Secret: When you empty your traps every 2-3 days, save the earwigs you collect in a sealed container with a little soapy water. This gives you a clear record of how many pests you're removing from your garden. Over time, you'll notice patterns in when earwigs are most active—this helps you adjust your trapping schedule. Also, keep a small spray bottle of soapy water nearby for quick disposal when you're working in the garden.

Frequently asked questions

How long does it take for an earwig trap to work?

Most DIY earwig traps start catching earwigs within 24–48 hours, but peak activity (and trap success) happens at night when they’re most active. Check your trap daily for best results—earwigs are sneaky and may not show up immediately! If you’re not seeing results after 3–5 days, try relocating the trap or adjusting the bait.

When is the best time of year to set up earwig traps?

Earwigs thrive in warm, humid conditions, so set traps in late spring through early fall (May–September in most regions). They’re especially active after rain or in damp basements. If you’re dealing with an indoor infestation, traps work year-round—but focus on prevention in dry winter months by reducing moisture.

Can I use beer or other liquids besides beer as bait?

Yes! While beer is classic, earwigs love any fermenting liquid or moist organic matter. Try:

• Apple cider vinegar (strong scent attracts them)
• Sugar water (mix 1 cup sugar + 1 gallon water)
• Overripe fruit (like bananas or citrus)
• Yeast water (dissolve 1 tbsp yeast in warm water)

What if my trap isn’t catching any earwigs? Troubleshooting tips.

If your trap is empty after a few days, try these fixes:

• Check placement: Move it to dark, damp areas (under sinks, mulch piles, or eaves). Earwigs hide in cool, moist spots.
• Refresh the bait: Stale beer or dried fruit loses its appeal—replace it every 2–3 days.
• Increase moisture: Add a damp cloth or sponge to the trap to mimic their ideal habitat.
• Try a different container: If they’re escaping, use a taller container (like a plastic bottle) with a narrow opening.

Are earwig traps safe for pets and kids?

DIY earwig traps are non-toxic if you avoid pesticides, but take precautions:

• Use pet-safe baits (like beer or fruit—never rodent poison or chemicals).
• Place traps out of reach of curious pets/kids (earwigs aren’t harmful, but the trap setup might be tempting!).
• Dispose of trapped earwigs far from your home (like in a sealed bag in the trash).
