  • Garlic Spray: Blend garlic cloves with water and a few drops of liquid soap. Strain and spray on plants.
  • Chili Powder Dust: Dust chili powder onto plant leaves and soil to repel pests.
  • Onion Trap: Bury a few onion halves around plants – insects will be attracted to the scent but won’t stick around.
