Worms in Peppers & Cherry Trees: Organic Controls That Work

Toronto gardener: worms inside peppers (crumble fruit) and cherries (appear after storage). No pesticides used. Asks for solution.

Pepper Worms: Likely European Corn Borer or Pepper Maggot

Cherry Worms: Cherry Fruit Fly (Rhagoletis spp.)

Both lay eggs on fruit; larvae tunnel inside.

Organic Controls

1. Bt (Bacillus thuringiensis kurstaki): Spray on foliage/fruit when eggs hatch (timing critical). Sold as Dipel, Green Step, MVP. Non‑toxic to humans/beneficials.
2. Diatomaceous Earth: Dust on fruit & soil. Abrasive to soft larvae. Reapply after rain.
3. Kaolin Clay (Surround): Spray on fruit — creates barrier, confuses flies. Works on apples/pears; likely on peppers/cherries.
4. Sanitation: Remove & destroy ALL fallen/infested fruit immediately. Breaks cycle.
5. Traps: Yellow sticky cards for cherry flies; pheromone traps for moths.
