Earwigs & crickets

A chirp, a pair of pincers or a jumping basement insect leads to different checks. Most incidental visitors can be removed while entry and moisture conditions are corrected. In a garden, confirm the animal feeding at night before treating a hole in a leaf as proof.

Your first decision

Remove indoor visitors

Sweep or vacuum individuals and reduce entry gaps. Improve ventilation or dehumidification where needed and remove damp cardboard or other unnecessary shelter.

01 / Identify

Recognize the signs

Earwig forceps
Earwigs have paired forceps at the abdomen tip. Nymphs resemble smaller adults; adults usually have short wing covers. The forceps are not a scorpion-like stinging tail.
Cricket form
Crickets have long antennae and enlarged rear legs for jumping. The straight ovipositor of a female cricket is an egg-laying structure, not a sting.
Stage and location
Cricket and earwig young hatch from eggs and grow through nymphal molts. Adults drawn to a door light and small stages repeatedly found in indoor shelter suggest different inspection priorities.

Look more closely

Compare the labeled examples and their limits. Images are independently enlarged, not shown at a common scale.

An adult female with a central egg-laying ovipositor between the rear cerci. The ovipositor is not a stinger. Other crickets and immature stages differ.

Differences that change the decision

A similar-looking organism can need a different response. Compare the evidence and what it changes.

Compare every column. On a narrow screen, scroll the table sideways.

TypeWhat to checkWhat changes
European earwigsNight-active insects shelter under damp objects and can eat plants as well as small arthropods.Inspect fresh garden injury after dark. Where they are eating pests or only wandering indoors, broad treatment is unnecessary.
Striped earwigsA different group sometimes attracted to lights; UC IPM describes the southern California species as primarily a nuisance rather than a plant pest.Species and observed feeding matter. Do not apply the European earwig's damage profile to every earwig.
Field cricketsOften dark, with conspicuous hind legs; adult males may chirp and arrivals can follow lighting or seasonal changes.Focus on entry and nearby cover, while checking vulnerable soiled fabrics if numbers are high.
House cricketsOften yellow-brown with dark bands behind the head; winged adults can chirp.Check warm shelter, food and fabric damage if activity persists. Confirm a source before treating every cupboard.
Camel or cave cricketsHump-backed, wingless, long-legged and silent; often associated with damp basements or crawl spaces.Drying and reducing clutter are more relevant than changing a light that is not attracting them.
Jerusalem cricketsLarge, wingless western insects with a rounded head and banded abdomen, often exposed by digging or rain.An alarming appearance usually does not justify control. Potato bug is ambiguous and can also mean unrelated beetles or woodlice.

What else could it be?

Cockroach nymphs

Lack the enlarged cricket jumping legs or earwig forceps. A clear side and top view helps distinguish a young insect.

Slugs and caterpillars

Can make similar plant holes. Look for the actual night feeder, slime, frass or webbing rather than diagnosing from damage alone.

Spiders

A camel cricket has six legs and antennae; a spider has eight legs and no antennae.

Inspect the right places

  1. Check shelter and entry

    Inspect accessible basement clutter, door gaps and damp ground cover beside the building. Note whether sightings concentrate near lights or in dark, moist areas.

  2. Confirm garden feeding

    Use a flashlight after dark at recently damaged seedlings, flowers or soft fruit. An earwig hiding in an already damaged fruit may not have caused the original injury.

  3. Check fabric evidence

    Where crickets recur, inspect stored or soiled textiles for fresh damage and actual insects. Old holes alone cannot identify the cause.

02 / Respond

Choose a proportionate response

For pesticides, the local product label determines the allowed pest, site, precautions and timing. Check safety and regional guidance.

  1. Remove indoor visitors

    Sweep or vacuum individuals and reduce entry gaps. Improve ventilation or dehumidification where needed and remove damp cardboard or other unnecessary shelter.

  2. Manage confirmed earwig damage

    Place rolled newspaper or similar shelter traps near affected plants in the evening and inspect them in the morning. Keep a catch and fresh-damage record; reduce excess nearby shelter and water without removing all beneficial habitat.

  3. Reduce cricket access

    Repair door sweeps and screens and reduce unnecessary exterior light near entrances where light-attracted crickets recur. For camel crickets, concentrate on damp shelter and access instead.

  4. Protect belongings

    Clean and dry affected textiles before storing them in protective containers. Persistent confirmed indoor activity warrants a source review rather than indiscriminate spraying.

Avoid these mistakes

  • Do not treat earwigs as an ear-burrowing parasite; the name is not a medical diagnosis.
  • Do not spray plants solely because an earwig was found nearby; it may be feeding on aphids or decaying material.
  • Do not use indoor insecticide as a substitute for fixing repeated entry or moisture.
  • Do not handle unfamiliar large insects merely because a guide says their group is usually low risk.

03 / Follow through

Check whether it is working

When to look again

For an earwig trapping program, UC IPM recommends daily trap checks. Editorial suggestion: compare new plant injury and catches together, and record indoor visitors during routine cleaning.

Evidence of progress

Fresh plant injury becomes tolerable and indoor sightings decline. A reduction in trap catch without inspecting the plant is incomplete evidence; not every outdoor earwig needs removal.

Record an observation ↗

Get help when…

  • Persistent indoor crickets with developing stages or continuing fabric damage need identification and source assessment.
  • A damp crawl space or suspected leak may need a building specialist.
  • Garden damage that continues without the suspected insect present should return to a broader plant diagnosis.
Prepare for a professional inspection ↗

Prevent a return

  • Keep damp clutter away from entry points and maintain appropriate drainage.
  • Use practical screen and door repairs and shield unnecessary outdoor lighting.
  • Inspect vulnerable young plants directly rather than scheduling preventive sprays.

Common questions

Why does a camel cricket not chirp?

Camel crickets are wingless and do not produce the familiar wing-based cricket song. Silence does not exclude a cricket.

Are earwigs always harmful in the garden?

No. They can consume aphids and other small animals. The decision depends on observed injury to susceptible plants, not their presence alone.
