Yep, baited traps. If you don't bait traps they seldom work!

You bait the trap, go to sleep, wake up in the morning and dispatch the critter.
After 4-5 sleepless nights I decided it was the only sensible solution.
Between the trap and my rampage I have taken reasonable control of the situation. No Raccoons for two nights but I am still chasing a big possum. For some reason he is not attracted to any bait I leave in the trap.
I watched him through the night vision goggles last night and he circled the pen, examined the trap without going inside and ambled off to try and open the door of the hen house.
I suspect some animal rights nut-job sent him and e-mail and warned him off.
