A customer has heard scratching in her walls over the last 2 months. We baited all areas of the house ( including roof space and under floors) and had no takes on any baits on follow up visits. The customer continued to hear the noises so we dug up some decking to find rat runs. The rat has been living in the cavity wall and leaving the property at night to feed. It hasn’t ventured in to the main parts of the house so hasn’t encountered any previously laid bait. The rat must of dug down the external wall and found a way in to the cavity space. As sneaky as this rat has been we are still able to get him. Baits placed along his main runs were just too tempting and as you can see from the photo has now consumed plenty. Now the holes have to be filled to prevent further rats using this great hideaway.
