I have been asked to undertake some recent new work in Chorley. Rats have been using a gap under the brickwork to the rear of a house to gain access through the cavity to the kitchen area.
As you can see from the pictures, the large hole behind the fridge in the kitchen, as black smear marks around it from were the rats have been passing through on a regular basis.
Rats have a natural grease on their body which they smear on to surfaces when they pass through things.
I have placed poison at the entrance to hole and under the floor in the house and an external box in the yard next to the large hole under the brickwork as shown in the picture.
