I agree that could be a problem depending on the circumstances. The time that I used the old style Dicon was over twenty years ago. We purchased a new home and our builder along with a couple of others had displaced many woodland creatures. The area had been used for cattle grazing with a stream running thru it, and little else. When they started building these new homes many animals, mice included lost their habitat. The mice were trying to get a safe place to nest. They got as far as the garage where they would find the Dicon. I would find their dehydrated bodies along the baseboards inside the garage. The old style Dicon seemed to work quickly as I was cleaning out their little furry bodies weekly. This went on for a couple of months before it just seemed to stop. My new neighbors all had much the same problem as well. The produce that I can buy now is not as powerful as the old one and that is why I was lamenting that is was no longer available.
