Shanghai McCoy blurted out in alt.home.lawn.garden:

Hi all - I haven't tried to poison this damned thing, but I have tried
one of the mole guillotines to no avail. A friend at work suggested used
kitty litter sprinkled around tunnel entrances- apparently the cat urine
scares moles away. Sounds logical to me, but before I subject myself to
a litter box, I'd like your opinion. TIA.

Call a professional to come set some traps.
I've had mole problems for yrs (because my neighbor has a grub farm going in
his yard). Even though I put down Grub-X twice a yr.
Traps got 3 moles in little over a week.

Most pro's make you sign a contract that has them coming once a week to check
or move the traps. THis contract costs X dollars. Then you pay per mole
caught.

It was well worth it for me.
