Thanks Elaine and Alice for the advice about combining products...excellent points!
thanks for this link Alice...I went to Lowe's this morning and scrutinized all the small print and could not for the life of me find anything that had BT in it..and to make matters worse they had no orchids other than some dried up in a bag..plants..very disheartening ...on both counts! I'm noticing TONS of pretty small moth-like things flying just above the grass lately..I wonder if they are related?
