Are there 'mounds' and holes in the yard, perhaps from moles, gophers or voles? We had that problem a while back and purchased a doohickey that hooks a garden hose to the tailpipe of your car. You enjoy a 15-minute martini-break with your neighbors while they're being suffocated underground. Very satisfying!

Hey--generally I LOVE animals....so please no scathing comments. Just those underground rat-wannabies we can all live without....I'm on your side here!

Good luck, keep us posted on the hosta munchers.

My mother is always complaining about voles (sp?) eating her hostas from the underground.

My hosta are in pots and something "cuts" them down at the surface. What could this be? What do I do to get rid of it?
