well ali,i'm not so sure if you can apply cooking oil directly to the plant.but sure worth a try...i'm actually working in the chemical agricultural industries and they have a product base on oil to be sprayed evenly to a plants infected by thrips.the mechanism of action is to suffocate the pest till dead.if you want to try,i'll advise you to try on just one leaf 1st to test if its work and to see if there is and risk to your nep plant...
