Hello, I've recently discovered tiny brown pests on my Dieffenbachia plant along with some tiny white pods or balls.I first wiped down the leaves, and then sprayed the leaves thoroughly with a mix of equal parts, water, alcohol, and vegetable oil along with a pump of soap. The next day, I gave my plant a thorough check and there were no evidence of any pests! But the spray has left the leaves with a oily shine. It has been 3 days now, and my question is, will the oil on the leaves interfere with the plants photosynthesis? I don't want to wipe off all the oil because I've read that the oil is meant to suffocate the bugs. Any help is wonderful. Thanks!
