Will Yates Pest Oil kill gnats and can I use it on my basil plant?
Unfortunately, our Pest Oil is not registered to control fungus gnats. We recommend 'Yates Gnat Barrier' as an effective physical barrier against fungus gnats in potted plants. It can be applied around edible plants including your basil. 'Yates Gnat Barrier' is made from natural abrasive pumice granules which are non-toxic and specialised to defend against fungus gnats. Granules also help to reduce water loss from the surface of your potting mix to retain moisture for your plant to access when needed.
