i have hives on both beans and cotton in north ms.hive placement is very important,also get to know the farmer,most of them will work with you any way they can.i put my name and phone number on the hive on the end hive on the stand.they have always given me a call ahead of spray time.around here they spray a pyrethroid and i stop the hive up for half a day,i have a small loss,but they rebound quickly.
