Homemade Oil Spray for Fruit Trees

Updated July 20, 2017

Keeping insects off of your fruit trees can seem a daunting task if you want to avoid using chemical insecticides. There is an easy, homemade remedy for dealing with pests who want to eat your tree's fruit. The mixture is called horticultural oil and is applied in the spring to the insects that were hatching during the winter. You apply the oil to the tree and suffocate the insects without causing any harm to the tree or the fruit.

Pour 1 cup of oil into a bucket.

Add 2 tbsp of liquid dish soap.

Dilute the oil and soap with 1 gallon of water and mix very well.

Pour the mixture into a spray bottle immediately after mixing it. Shake the bottle. It will be necessary to shake the bottle often while spraying the trees.

Spray the oil solution all over your fruit trees.

Tip

Cottonseed oil is the best for tree sprays, but you can also use soybean and vegetable oils.

Warning

Spray the oil mixture when the wind isn't blowing so you don't get it in your eyes.

Things You'll Need
