How to make insect spray for orange trees

The majority of pest problems affecting orange trees are not severe enough to harm the tree. If the pest infestation becomes severe and the tree's health declines, an insecticidal spray is required. Pests that cause periodic problems in orange trees include grasshoppers, aphids and scale insects. Gardeners have several treatment options available. They can make their own insecticidal spray from concentrated chemical pesticides, or use a homemade product that usually works just as well. These products kill the offending insect and control future infestations.

  1. 1

    Identify the pest infesting the orange tree.

  2. 2

    Use a plastic spray container that holds at least 1 gallon.

  3. 3

    Remove the sprayer's lid. Fill the container with 1 gallon of warm water.

  4. 4

    Add 1 tsp of an insecticidal soap or liquid dish detergent. Swirl the ingredients until they are thoroughly mixed.

  5. 5

    Add 4 tsp of neem oil to the container of soap and water.

  6. 6

    Replace the top on the bottle or sprayer. Shake the bottle, thoroughly mixing the ingredients. Add 1 tsp of soap to the mixture if the neem oil does not dissolve.

  7. 7

    Spray all parts of the orange tree, including all leaf surfaces. Spray the insecticide on the soil beneath the tree, saturating it. Shake the container of insecticide while spraying the product to keep it mixed.

  8. 8

    Reapply the product if rain occurs within 24 hours and washes it off the orange tree. Watch the insects' activity over the next week and reapply the insecticide if the insects are still active. Apply monthly applications of the product to prevent further insect infestations.

Tips and warnings

  • The neem oil insecticide remains usable for up to eight hours after mixing.
  • Increase the amount of neem oil and insecticidal soap if the insects remain a problem. Make a stronger concentrate by doubling the amount of both ingredients.
  • Neem oil works well to control sucking and chewing insects.
  • It works by controlling the insect's hormones. It stops the pest from eating, mating and producing eggs, eventually killing it.
  • Always mix insecticidal pesticide concentrates according to label instructions. Most pesticides are toxic, so keep the product out of reach of children and pets, and out of waterways.
