The large Swim Through Comstock Beaver Cage Traps take beavers of all sizes.  Pictured are six beaver, three adults weighing in the 30-40 pound range with three young beaver and a muskrat.  Note that the beavers are not much larger than the muskrat.  All seven animals were taken in the 12x18x39 cage traps, set upside down on the bottom of runs.  What’s great about this trap is that it will take muskrats, otter and beaver of all sizes and will double as a land trap when needed to catch raccoons, badgers, fox, bobcat, even woodchucks and an occasional coyote, just about any animal in that size range.
