i agree with 5cents, get some #5's for them beavs....how are u doing it with the #3's tho? are u drowning them or just staking because just solid staking a beav will give u alot of pullouts also. a #3 will catch a beaver, but i wouldnt count on that. ive heard of them being caught in #1.5's but thats not the trap that you would use for them, there accedents. it all depends on the catch and a whole lot of luck. if i was u, i would save up for some #5's. just my 2 cents, but for beaver u need a beaver trap. im not saying that the #3 wont hold them. it just wont hold them as well.
