How to Make White Oil


Garden Pest Control

Whit oil is great for organically controlling pests, like these aphids

White oil is among the safest and most effective organic ways of controlling many sap sucking and leaf chewing pests in the garden. Gardeners have been using white oils for centuries, so they’ve been thoroughly tested. The best thing about white oil is that you can make it yourself!

White Oil Ingredients:

  • Two cups of vegetable oil
  • Half a cup of washing up liquid

Method:

Put the oil and washing up liquid into a jar or bottle. Put the lid on and give it a good shake and you’ve got concentrated white oil.

Label the concentrated mixture and store it in a cool, dry place. It’s a good idea to also label it with the dilution rate – two dessert spoons per litre of water.

Over time the two liquids may begin to separate again, just give them a good shake prior to use.

Use:

Dilute the concentrated white oil by adding two dessert spoons (about 20mL) to one litre of water. Mix well and add to a sprayer.

On hot days, it’s best to spray your plants in the cool of the morning. Cover both sides of the leaves and all of the bark. Don’t use the white oil on hairy or soft leaved plants like lettuce, because it will burn the leaves.

White oil will control scale, aphids, mealy bug, citrus leaf miner and caterpillars. The white oil blocks the pests breathing pores and suffocates them. Because it works in this way, there is no chance of resistance to it. White oil is a perfect organic garden pest solution!
