The Minnesota Trapline Tom Miranda Kill Squak Trap Call makes quiet rodent squeaks for 10 seconds then silent for 10 seconds. Use at the trap, in live traps with insane results. The call is barely auditable to humans but animals can easily hear it. Uses 2 AAA batteries (not included) and Duracell Batteries will run the call continuously for 10 days.
