As winter grinds on on the Great Plains of the U.S., and talk of eradicating pests both large (deer) and small (aphids), I have a question about a possible control for squirrels. During winter these beasts are fairly easy to reel in, a little bird seed and or corn and they are right at your door. The problem is in the spring and summer when the plants in the garden (chile and others) grow green, the tree rat digs, rips and murtilates my, and our, beloved El Grande. The questionable control is DeCon. This is rat/mouse poison. It contains Warfarin or Coumadin, which prevents clotting of the blood and silica or glass which cuts the insides causing bleeding. Will this work on squirrles? I know they will eat it but will it, ah, you know, take care of them.
