Video: How to Make a Trap for Castor Mound Set

This beaver trapping technique has been around for a long time and for good reason. There are few more effective ways to lure beavers into a trap than to find one of their telltale slides, create a scent mound at the base, and cover it with a rival beaver’s castor bean.

Beavers have castor sacs and release castoreum in combination with urine to mark their territories. This scent is strong and lingers around swampy areas where the creatures are known to live, especially during the early spring breeding season.

Once the mound is built, Steve and I place the MB-750 coil trap just under the water and attach the drowning chain to a heavy plate which we place in deeper water. We also make sure it is deep enough to quickly drown the beaver once the trap is opened.
