Garden pest

Earwig

Nocturnal insects with rear pincers that chew seedlings, flowers, and soft fruit.

Crops often hit: Lettuce, Seedlings, Corn silks, Strawberry

How to identify

  • Reddish-brown insects with forceps-like cerci at the rear
  • Hide under boards, mulch, and pots by day
  • Ragged chewing on tender growth overnight

Damage: Chewed seedlings and flower petals; sometimes helpful as predators too.

Control methods

  1. Roll newspaper or use oil traps overnight and empty in the morning.
  2. Reduce dense mulch against seedling stems if damage is severe.
  3. Tolerate low numbers — earwigs also eat aphids and soft insects.

What products to use

We list product types and what to check on the label — not brand rankings, prices, or “we tested” claims. Always follow the label for your crop, and prefer the least disruptive option that works.

  • Oil/soy-sauce traps (DIY)

    When: Seedling damage is concentrated

    Look for: Shallow traps with oil; empty daily — no need for a commercial insecticide in most gardens
