Garden pest

Tarnished plant bug

Also called: Lygus bug

Small mottled bugs that pierce buds and fruit, causing tip burn and catfacing.

Crops often hit: Strawberry, Bean, Pepper, Lettuce, Tomato

How to identify

  • Oval bugs about 1/4 inch with bronze/brown mottling and a yellow triangle on the back
  • Black-tipped yellow nymphs
  • Catfaced fruit and dead growing tips

Damage: Deformed strawberries, beans, and peppers; tip dieback on greens.

Control methods

  1. Mow weedy borders before bloom so bugs do not migrate into crops.
  2. Row cover on strawberries until bloom if pressure is high.
  3. Hand-pick on small plantings early morning.

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.

  • Insecticidal soap or labeled pyrethrin

    When: Nymphs active on buds/fruit

    Look for: Tarnished plant bug or lygus listed on the crop; adults are tougher
