I have been cautious about using rat/mice poision in my areas.. Don't wqnt that stuff to get into the wrong mouths, and unintentionally poision something. There is a way to0 creat mouse poison \"traps\" using 4\" black corr tubing like you can use for drainage. I have tried that out back of my house where I ahave a big problem.
I cut ^\" of that Black drainage tubing. Put approiate dosage in to put a hurt on the little buggers. Secure the tubing with rocks so it isn't easily moved. Place ia area where you have had problems. Replace the stuff as needed.
I really like the Snap-traps, however is unrealistic to place these around the woods, IMHO.
