I was pleased with the noticeable decrease in mice running around, UNTIL I started finding stashes of turquoise pellets all around other areas of the property (in the corners of my patio chair seats in the back yard – to which the dogs had complete access, inside my bowling bag – via a tiny hole chewed in the side, and including the dessicated bodies of several mice, etc.). I instantly stopped putting out bait, but today, five years later, I still have to be aware and vigilant. I recently had my kitchen remodeled, and when the contractor tore out the old walls to expose the studs, there were turquoise pockets of bait still “stored” here and there throughout the structure. At the least, I had to emphasize very careful cleanup, and disposal of the construction debris. REALLY SCARY!!
