I believe I saw that you can spray a plant that is infested with oil..
Can someone please enlighten me about this as I can find nothing with a

Hi Annabel.

The oil in question is Tar oil which should be applied during the winter
months only. Red spider mites thrive in humid, dry conditions and loathe
water, so forget the Tar oil and get spraying. I used to control them with
Derris dust but not now as using it also controls the predators.
