Naw UB, I ain't no Weasel trapper nowadays. Very few Weasels around.
Acid rain, clear crop farming, herbicides, pesticides, asphalt, cement, malls, housing developments and urban sprawl are all factor in the low Weasel population.
I have been humbled the past few years.
Back in the day, my average field Mouse catch was 4-6 Mice per 1 Weasel catch. Use the Mice for added bait/eye appeal.
With 8 Mice caught, in 2 boxes...you were very close on connecting with a Weasel, using my averages.
