Earwigs leave when you dry damp hiding spots, trap night feeders, and shield tender plants before petals, fruit, and seedlings get chewed.
Earwigs can turn up fast after warm, damp nights. Leaves turn ragged overnight, petals look nibbled, and soft fruit picks up small gouges.
These insects hide by day and feed after dark. They like mulch, boards, leafy clutter, cracked pots, and any shady patch that stays damp. That habit gives you a clear opening: change the places they hide, then trap the ones still hanging around.
You don’t need to drench the whole bed to get results. In most gardens, a few small moves work together. Start with moisture, shelter, and timing. Then protect the plants earwigs like most.
What Earwigs Are Doing In Your Beds
Earwigs are mostly night feeders. During the day, they tuck into cool, moist shelter. After dark, they come out to chew soft plant tissue. Seedlings are easy targets. So are dahlia petals, marigolds, clematis, strawberries, raspberries, blackberries, and sweet corn silks.
They also eat aphids and insect eggs. If earwigs are hanging out in a fruit tree and aphids are the main issue, wiping them out can backfire. If they’re shredding seedlings or chewing blooms you care about, that’s a different story. Target the trouble spots instead of treating the whole garden like one giant problem.
Take a flashlight and inspect the soil surface, pot undersides, mulch edges, and the base of damaged plants. If you see earwigs clustered there, you’ve found the source, not just the symptom. The UC IPM earwig page also notes that damp hiding places and night feeding are part of the usual pattern.
Getting Rid Of Earwigs In The Garden Without Overdoing It
Start with the bed itself. Earwigs pile up where the surface stays damp and cluttered. Thin mulch away from seedling stems. Lift boards, flat stones, and empty pots that sit on the soil. Pull weeds and trim thick growth that shades the crown of tender plants.
A soaked surface at night is almost an open invitation. Water early in the day so the top layer dries by evening. Drip lines help even more.
Protect the plants that suffer first. New lettuce, basil, beans, marigolds, dahlias, and ripening strawberries tend to show damage fast. Seedlings in trays or small starts in the ground may need a short spell of extra shielding until stems toughen up.
| Problem Spot | What To Change | Why It Cuts Earwig Pressure |
|---|---|---|
| Mulch pressed against stems | Pull mulch back 2 to 3 inches from seedlings and crowns | Removes a cool daytime shelter right beside tender tissue |
| Boards, stones, or spare pots on damp soil | Lift or move them to a dry area | Breaks up the dark hiding spots earwigs use before dawn |
| Late-evening watering | Water in the morning | Lets the soil surface dry before night feeding starts |
| Heavy overhead irrigation | Use drip where you can | Keeps the upper layer less damp and less inviting |
| Weedy, crowded bed edges | Trim and clear the border | Reduces shady shelter and makes traps work better |
| Fresh damage on flowers | Set traps right beside the damaged clump | Puts the catch point where night traffic is heaviest |
| Strawberries or raspberries getting gouged | Pick ripe fruit as soon as it colors up | Leaves less soft food in the bed overnight |
| Stone fruit with earwigs climbing the trunk | Use a sticky trunk band and pick ripe fruit fast | Blocks access to fruit and cuts feeding on softening harvests |
How To Trap Them So The Numbers Drop
Once you’ve cut shelter and moisture, traps start pulling their weight. You want to remove the earwigs still using the bed each night.
Good trap choices include:
- Rolled newspaper laid on the soil at dusk
- Short pieces of hose or bamboo set near damaged plants
- Upturned flower pots loosely filled with straw or hay
- A low-sided can with vegetable oil plus a drop of fish oil or bacon grease
Set traps out at dusk. Check them just after sunrise. Dump the catch into a bucket of soapy water, reset the trap, and repeat each morning. Give it a week.
The RHS earwig advice points to hay-filled pots as a handy trap for ornamentals, while UC IPM lists rolled newspaper, bamboo tubes, short hose pieces, and oil traps. Put traps near the plants being hit, not at the far edge of the yard. A trap a few feet off target can miss the worst pocket.
How Long You Should Keep Trapping
Give it at least a week. If catches fall morning by morning, stay with it until the numbers stay low for several days in a row. If catches stay heavy, the bed still has too much damp shelter nearby. Go back and clear what you missed.
When Earwigs Are Worth Leaving Alone
Earwigs aren’t pure plant wreckers. On fruit trees, they can feed on aphids. If you spot them in an apple or plum tree with no fruit damage and clear aphid pressure, leave that patch alone and save your effort for seedlings, flowers, corn, and soft fruit where the chewing is plain.
A simple rule works well:
- Act when you see fresh chewing on tender growth, petals, or soft fruit
- Hold off when earwigs are present but damage is light and aphids are active nearby
- Check again after dark before you decide the next move
| Damage Level | What You’re Seeing | Best Next Move |
|---|---|---|
| Low | Earwigs present, little to no chewing, aphids also present | Leave them alone and watch the spot for a few nights |
| Light | Small nibbles on older leaves or a few petals | Clean up shelter and start one or two traps |
| Moderate | Fresh chewing on seedlings, blooms, or soft fruit | Trap daily, dry the surface, and pick ripe fruit early |
| High | Repeated night damage in the same bed | Trap near each hot spot and recheck the bed after dark |
| Fruit-tree issue | Earwigs climbing trunks to reach softening stone fruit | Add a sticky trunk band and harvest as soon as fruit ripens |
Do You Need A Spray At All?
Usually, no. Once the bed dries out, hiding places shrink, and traps run for several mornings, numbers often fall hard. Make sprays the last step, not the first.
If you still reach for a product, treat that step like surgery, not a blanket move. Use it only on the exact site listed on the label and only where damage is active. The EPA’s Read the Label First: Protect Your Garden page is a good reminder that the label tells you where, when, and how a garden product may be used.
Spot treatment also avoids a broad knockdown in beds where earwigs may be eating aphids. Wide spraying over mulch, blooms, and edible beds can leave you with more mess than relief.
Common Mistakes That Keep The Problem Going
- Watering late in the day
- Leaving boards, empty pots, or thick debris on damp soil
- Letting mulch touch seedling stems
- Trapping once, then stopping before the catch drops
- Spraying first and skipping the cleanup that fixes the bed
- Treating fruit trees the same way you treat damaged flowers or seedlings
What To Expect After You Start
You should see less fresh chewing within several days if you hit the right spots. Seedlings stop disappearing. Petal damage slows. Strawberries and raspberries pick up fewer new gouges. Keep trapping until catches stay low for a few mornings in a row.
If damage keeps showing up, go back outside after dark. Night checks beat guesswork. You may find a damp pocket under edging, a stack of nursery pots, or thick mulch against stems that kept the cycle going.
A steady, calm approach wins here. Dry the surface. Strip out hiding places. Trap at dusk and empty in the morning. Protect the tender crops that earwigs like most. That mix is usually enough to turn the bed around without drenching the whole garden in product.
