Combating psyllids

Have you detected psyllids? ✅ With GREEN GUARDIA neem oil, repellent spray, and lacewing larvae, you can combat psyllids naturally and protect your plants sustainably.

1. General information about psyllids

Psyllidae are small, flying insects that feed on plant sap, similar to aphids. They leap away when disturbed—hence the name "flea." Psyllidae attack many plant species, such as fruit trees, vegetables, herbs, and ornamental plants.

As they feed, they release toxins that cause leaf deformities, impaired growth, and sticky honeydew . This honeydew also attracts sooty mold, further weakening plants.

2. Detecting aphid infestation – typical signs

You can recognize a leaf psyllid infestation by typical symptoms:

  • Deformed, curled leaves, especially on young shoots
  • Sticky honeydew on leaves that attracts ants and fungi
  • Blackish deposits (sooty mold) on the plant parts
  • Small, 2–4 mm large insects that jump or fly away when touched

A severe infestation weakens the plant considerably and can significantly reduce the harvest.
