If Asa says it will work then it will work...
I use a bait for most of mine...
I use 2 cans of jack mackrell (sp)
Honey, beaver castor, and ASAFOETIDA
I put the 2 cans of fish in a quart jar, then add about 1/2 to 1 teaspoon of beaver castor then about 1/2 ounce of ASAFOETIDA
I then add enough honey to make it a thick paste... the honey keeps it from spoiling...
Bobcat urine is also an attractor... I put a piece of cotton rag on each one of my bucket handles and give it a squirt of bobcat urine...
This works for me...
Another tip, if you put a knife to a ringer you are costing yourself a ton of cash.. Taxidermist love these critters and will pay dearly for them...
