If it gets wet, it stops working but once dry, works again. It kills every bug except it will not hurt earth worms. Has anyone else here heard of it? Even if the martins don't eat it like the chickens do, it will keep their nest free of motes and such just being on the floor of their nest
If everyone here thinks it is safe, I will clean out that pm house this weekend and let dry well, then....sprinkle DE on every nest floor
