What are the advantages of using a 2 door trap versus a 1 door trap?
It is actually a matter of preference. Unlike old-fashioned box traps, most Havahart traps open at both ends so certain cautious species have the feeling of confidence that he is going to get out again. A one door trap allows the animal to walk the whole way into the trap and past the trip plate when the doors shut ensuring even a large animal will be caught.
