Ragged leaves and chewed seedlings can appear quickly when earwig populations rise. These nocturnal insects hide in cool, damp spots during the day and emerge at night to feed on flowers, vegetables and tender young plants.
The good news is that small numbers of earwigs usually aren’t harmful and can even help by eating other garden pests. Problems begin when their population grows large enough to damage new growth. Regular inspections, simple traps, moisture control and targeted treatments when needed can protect plants without treating the entire yard.
Start With the Places Earwigs Hide
Before reaching for broad pesticide treatments, inspect the locations where earwigs are most likely to shelter during the day. Check under flowerpots, stepping stones, mulch, boards and other cool, shaded areas near planting beds. Reducing these hiding places makes the garden less attractive to earwigs.
Homeowners who face persistent, large infestations sometimes consult pest control professionals to locate hotspots and apply focused treatments. Whether you hire an expert or handle it yourself, concentrate on the areas where earwigs feed and hide rather than treating the whole property indiscriminately.
Understand the Earwig Life Cycle
Soil structure and sheltered spaces can provide overwintering sites for earwigs. Female earwigs often dig cells in the ground where they lay clusters of eggs. In spring, the young emerge and begin foraging, and tender seedlings and flower petals can be easy targets when numbers are high.
A few earwigs in the garden are usually harmless; they prey on aphids and other small pests, so total eradication is neither necessary nor desirable. The objective is to keep earwig numbers low enough that they don’t cause meaningful plant damage.
Clearing debris and damp hiding places in fall and early spring helps reduce overwintering populations. If earwig numbers remain high and plants continue to suffer, targeted control measures may be needed.
Match the Treatment to Your Yard
Modern pest management favors precise, localized actions over broad applications. Before choosing a control method, identify which sections of your garden stay wet or shaded for long periods.
Pay special attention to:
- Areas around hose bibs, birdbaths and irrigation equipment that stay damp.
- Water collecting beneath potted plant trays.
- Thick ground cover near foundations, decks and other sheltered spots.
- Mulch, boards, stones and other objects that offer dark hiding places.
Begin by correcting the conditions that attract earwigs: move pots when necessary, remove unnecessary debris and avoid leaving the soil surface wet overnight. If you choose to use a bait or other product, select one labeled for earwigs and for the specific location and follow the label directions carefully. Focus treatments on problem areas rather than treating the entire garden.
Check the Garden Regularly
Detecting pest activity before significant plant damage occurs makes control much easier. Regular monitoring throughout the growing season is a core principle of integrated pest management.
Inspect leaf undersides, garden borders, mulch and the soil around vulnerable plants several times a week during periods of high activity. Earwigs do most of their feeding after dark, so take a flashlight into the garden after sunset to confirm whether earwigs are chewing your plants or if slugs, snails or other pests are responsible.
Finding a cluster of earwigs under a saucer or in a damp patch after rain indicates where conditions may be too moist and where adjustments to watering or removal of hiding places are needed. Keep simple notes on where and when you find earwigs to help identify patterns and decide where traps or controls will be most effective.
Try Traps and Habitat Changes First
You don’t always need chemical treatments when earwigs appear. Simple traps and habitat modifications can often keep populations manageable.
Try the following:
- Place rolled-up damp newspapers or cardboard tubes near flower beds overnight, then remove and discard captured insects in the morning.
- Reduce excess moisture around vulnerable plants by adjusting irrigation and improving drainage.
- Bury a low-sided can with about 1/2 inch of oil in the bottom, set with the rim level with the soil near affected plants just before dark to trap earwigs.
- Prune low branches and thin dense plantings where appropriate to increase sunlight and airflow in persistently damp areas.
Check traps each morning and dispose of captured earwigs. Continue monitoring to see whether plant damage decreases. These methods can also reveal where earwigs are most active before deciding whether additional treatment is necessary.
Protect Seedlings and Young Plants
Young vegetable starts and annuals are especially vulnerable. Ragged leaves and chewed stems can set back small plants before their root systems are established.
Begin with traps, cleanup and moisture control, giving new plants extra attention during their first weeks, especially in beds that have had earwig issues before. If feeding damage continues, consider products that are labeled for earwig control and appropriate for the plants you are protecting—always read and follow label directions.
For severe or persistent problems, a professional can help pinpoint concentration areas and determine if stronger or more targeted measures are warranted.
Clean Up Earwig Hiding Places
Routine yard maintenance removes many of the cool, damp spots earwigs prefer. Clear fallen leaves, decaying wood and unnecessary debris from garden borders. Keep firewood raised off bare soil and place pots on risers so air can circulate underneath them.
Adjust watering habits by irrigating early in the day rather than in the evening to allow the soil surface to dry before earwigs become active. You don’t need to dry the entire garden; the goal is to avoid creating unnecessary damp hiding places close to vulnerable plants.
When to Call a Professional
For most gardens, regular inspections, cleanup, moisture control and simple trapping are enough to keep earwigs under control. Consider professional help if damage persists despite these steps, if you regularly find large numbers of earwigs, or if earwigs begin appearing indoors. A pest control expert can also assist if you’re unsure which pest is causing the damage.
Keep Earwigs Under Control
You’ll likely always have a few earwigs in the garden, and that’s normal. The aim is not total elimination but maintaining a healthy garden where a small number of insects don’t destroy seedlings before they have a chance to grow. Check beds regularly, remove damp hiding places, set traps when numbers climb and use targeted treatments only when simpler measures aren’t sufficient.
