Uses for Neem Oil
It can be used to treat many garden problems, such as:
  • Insects: Neem oil kills or repels insects and mites, like aphids, whiteflies, snails, nematodes, mealybugs, cabbage worms, gnats, moths, cockroaches, flies, termites, mosquitoes, and scale. Some pests die right away and others are prevented from maturing from their larval state. Plus, neem oil tastes horribly bitter and repels some pests.
  • Fungus: Neem oil helps prevent fungal diseases like black spot, anthracnose, rust, and mildew.
  • Disease: Neem oil also attacks harmful plant viruses.
