If you use a preventive direction you'd be better off and have a lot less chance of ever getting an infestation. I spray with neem while in veg. doing it about twice to 3 times in a 6 or 8 week period. Then one more time while in flower. Before they start to accually bud. By the time you harvest you will have no worries of that terrible neem taste on your finished product.
