How long does the shipped package of Fly Predators last if not opened?
Once Fly Predators start hatching they need to be put out within the next 2 days, they will survive for up to 5 days in the bag after emergence. Any longer you are losing out on the effectiveness of their fly control as they are looking for fly cocoons as food source. If they can't find a cocoon then the female absorb some of their eggs as a food source.
So it is best to release them as soon as you see 12-20 active in the bag.
