White Oil Spray
This is a simple but effective spray, made using just two ingredients – soap and oil. It works by coating soft body insects, like aphids and mites, in oil. The added soap helps the oil stick to the bugs.
To make, just mix a cup of vegetable oil with a quarter cup of liquid soap. Shake this well until it turns white in color – hence its name!
This is a concentrate which needs to be diluted before using. When you want to treat your plants, mix one tablespoon of this liquid with four cups of water. Re-apply every five to seven days.
White oil concentrate will keep for approximately three months in a sealed container or jar.
