Ragged leaves and chewed seedlings can appear quickly when earwig numbers rise. These insects hide in cool, damp spots during the day and emerge at night to feed on flowers, vegetables and tender young plants.
A small number of earwigs is usually not a serious problem; they can even help by eating other pests. Damage becomes a concern only when populations grow large enough to harm new growth. With regular inspection, simple traps, moisture management and targeted control when needed, you can protect vulnerable plants without treating the entire yard.
Start With the Places Earwigs Hide
Before reaching for broad pesticides, inspect the likely daytime hiding places where earwigs shelter close to plants. Check beneath flowerpots and their saucers, stepping stones, mulch, boards, stacked lumber, landscaping stones and other cool, damp hiding spots. Clearing or relocating these areas makes the garden less inviting to earwigs.
When infestations are localized but beyond what trapping and cleanup can manage, some homeowners bring in professional help to locate hotspots and address larger populations. Whether you hire a pro or tackle it yourself, concentrate on the specific spots where earwigs feed and shelter rather than treating the entire yard indiscriminately.
Understand the Earwig Life Cycle
Earwigs overwinter in protected locations in soil, debris and other sheltered spots. Females often dig small cells in the ground to lay egg clusters in cooler months, and young earwigs emerge in spring to search for food. Because juveniles prefer tender tissues, newly planted seedlings and flower petals are especially vulnerable when populations are high.
While a few earwigs are beneficial predators of pests such as aphids, the goal is to keep their numbers low enough that they do not cause noticeable damage. Clearing debris and reducing damp hiding places in fall and early spring helps reduce overwintering success and the number of spring hatchlings.
Match Treatment to the Yard
Effective pest management favors precise, localized actions over blanket treatments. First identify areas of the garden that stay shaded or wet for long periods, because these microhabitats are most attractive to earwigs.
Inspect spots such as:
- Damp soil near hose bibs, birdbaths and irrigation equipment.
- Water that collects beneath plant trays and pots.
- Thick groundcover next to foundations, decks or fences.
- Mulch layers, stacked boards, stones and other objects that create dark refuges.
Start by correcting conditions that draw earwigs in: move pots when needed, clear unnecessary debris, improve drainage, and avoid leaving soil surfaces wet overnight. If you decide to use baits or other products, choose ones labeled for earwigs and the specific garden area and follow the label directions carefully. Apply treatments only to the problem zones rather than across the whole property.
Check the Garden Regularly
Regular monitoring is a core part of integrated pest management and makes control far easier. During active periods, inspect leaf undersides, mulch, borders and the soil around vulnerable plants several times a week.
Because earwigs feed mainly after dark, check the garden with a flashlight after sunset to determine whether earwigs are the culprits or whether slugs, snails or other pests are causing damage. Lifting a saucer after a rainy spell and finding many earwigs underneath is a clear sign that the area is too damp and needs attention.
Keep simple notes on where and when you find earwigs and what plant damage looks like. These observations reveal patterns and show where traps, habitat changes or targeted treatments will be most effective.
Try Traps and Habitat Changes First
Often you can manage earwigs without resorting to chemical controls. Try these low-impact approaches:
- Place rolled damp newspapers or cardboard tubes near beds overnight and dispose of captured insects in the morning.
- Reduce excess moisture around susceptible plants by adjusting watering schedules and improving drainage.
- Bury a shallow can with about 1/2 inch of oil or soapy water so the rim is level with the soil; check it in the morning and empty any trapped earwigs.
- Prune low branches and thin dense groundcover to increase sunlight and airflow in persistently damp areas.
Monitor traps daily at first and continue observing plant damage. These methods both reduce earwig numbers and help you locate hotspots before deciding whether additional treatment is needed.
Protect Seedlings and Young Plants
New vegetable starts and annuals are especially susceptible to setbacks from earwig feeding. Give newly planted seedlings extra attention during their first weeks by using traps, minimizing shelter and adjusting watering so soil surfaces dry before nightfall.
If damage persists despite these steps, consider targeted baits that are registered for earwig control and labeled for use around the specific plants you are treating. Always follow label instructions closely. For severe or persistent problems, consult a pest professional who can identify concentration sites and recommend appropriate options.
Clean Up Earwig Hiding Places
Routine yard maintenance removes many of the damp, cool refuges earwigs prefer. Rake away fallen leaves and decaying wood from borders, keep firewood stacked off the soil, and raise pots on risers to improve air circulation beneath them.
Modify watering practices by watering early in the day whenever possible so surfaces dry before night. The objective is not to make the entire garden arid, but to avoid creating unnecessary damp microhabitats close to vulnerable plants.
When to Call a Professional
For many gardens, inspection, cleanup, moisture control and a few traps will keep earwigs at tolerable levels. Consider professional help if plant damage continues despite these measures, if you consistently find large numbers of earwigs, or if they begin appearing inside your home. A trained technician can pinpoint problem areas, advise on effective localized treatments and help you protect prized plantings.
Keep Earwigs Under Control
You will likely always see a few earwigs in the garden, and that is normal. The aim is not total eradication but a healthy garden where occasional earwigs do not overwhelm seedlings or newly established plants. Regular checks, thoughtful habitat changes, targeted traps and focused treatment only when necessary will keep earwig activity at manageable levels while preserving beneficial insects and garden health.
