toker1 is correct prevention is better than responding ,if you need to spray do it in veg and if they come back in bloom I dump a couple of thousand lady bugs and knock the shit out of them , I believe the directions say every 7 to 10 days (If I remember correctly) , if you have pests then take them some where that spraying the entire plant over/under leafs,stems and soil, drench the shit out of them a couple of times and you should be good
