Beavers are in love right now. Castor mounds catch jealous males and will catch cheating females.

Another quick effective set...at the edge of the dam..

Stink stick ..10 inches behind the trap .

In and out in no time

If you're going to use lure at your set forget about castor and use sac oil. I found that a non-aggressive lure works better in these small ponds.

The tray system Swamy is talking about is worth a shot. I’m definitely building some for my beaver “tool box”.
I’ve only watched about 10 minutes of Dave Lafforthuns DVD before I had to take off last night, but that video is already worth the $$.
Like Dave mentioned in the beginning, caster is a mood set. If it ain’t in the mood, it ain’t going there.
