This system seems to work well. I started dispensing on top of an equipment shed several months ago and have seen a dramatic reduction of rats running across the roof. Before dispensing, there would be many rats per hour run by the CCTV camera. After about 4 months, there are about 3 to 5 per day. A second unit has been on the ground for a couple of months and the camera shows the rats still coming in, but at about half as many as when I started. Hopefully they will also thin out as time goes by.
