Green Pepper Pests and Bug Damage: Causes & How to Fix It

Holes in the leaves of your green pepper, tiny insects crowded on the undersides, white flies rising when the plant is shaken, or seedlings cut off overnight. Even when you cannot see the insect, the shape of the damage narrows down the culprit.

Check these first

  • What shape is the damage: round holes, only veins left, white trails, or a pale stippling?
  • Where are the insects or droppings: under the leaves, on new shoots, or at the base?
  • If nothing is visible by day, check at night or early morning for cutworms and slugs.

Most likely causes

From the pests and diseases recorded for this plant, the ones whose symptoms match, most serious first. Symptoms alone rarely confirm a cause, so use the linked page to check the signs and treatment.

Thrips

Silvery white to brown scarring spreads over leaf and fruit surfaces. Flowers discolor and drop, and fruit is left with keloid-like scar tissue.

How to identify and treat: Thrips

Helicoverpa Bollworms

Round holes are bored into fruit and buds, the inside eaten out and packed with frass. Rot spreads from the entry hole, leading to fruit and bud drop.

Twenty-eight-spotted Ladybird

The leaf surface is shaved thin, leaving a fine net-like pattern of feeding scars. Heavy feeding browns and kills the leaves and scars the fruit surface as well.

What other growers did about it

A page like this one can tell you what green pepper pests and bug damage is and what to try. What it cannot tell you is what actually happened to someone who had it on the same plant, at the same point in the season, and what they did next.

Gadenin is a free garden journal built around that. You photograph the plant, tag what you are seeing, and the entries line up by date for each plant you grow.

  • Tag the problem and the app tells you how many other growers have logged the same thing on the same plant.
  • Growers who make their records public can be followed, so you can read what they did and how it turned out.
  • Next season your own entries come back at the same point in the year, so you check the plant before it starts.

Free on iPhone. Recording, tagging and reading public records cost nothing.

Log when you spotted the pest and what you sprayed or removed by hand. Next year you will know when to start checking.
