Pest identification
What's eating my jalapeño?
Aphids
Signs: Sticky shoot tips; mottled or puckered leaves from virus infection; honeydew encourages sooty mould
Control: Reflective mulch under plants; insecticidal soap sprays; beneficial insects; remove heavily infested growing tips
Thrips
Signs: Silver-grey streaking and scarring on fruit skin; bronzing of leaves; thrips also spread tomato spotted wilt virus
Control: Blue sticky traps; spinosad spray; remove weeds and plant debris; introduce Amblyseius cucumeris predatory mites
Pepper weevil
Signs: Oviposition punctures on young pods; larvae feeding inside cause misshapen or dropped fruit
Control: Collect and destroy dropped pods; spinosad or pyrethrin; clean up crop residues thoroughly at season end
European corn borer
Signs: Larvae tunnel through pepper walls leaving frass; compromised fruit rots quickly
Control: Btk sprayed at egg-hatch; spinosad; pheromone traps for adult monitoring

Jalapeño pests — FAQ
What is eating my jalapeño?
Jalapeños share the pepper pest complex: aphids are the top threat, spreading mosaic viruses quickly. Thrips scar developing fruit skin. Pepper weevils and European corn borers bore into pods. In cool wet gardens, slugs attack low-set fruit. Monitoring and early intervention prevent the greatest losses.
