How to Find Entry Points for Mice and Rats
If you cannot find the entry point where mice or rats are entering, then buy a trail camera from Amazon. They start at around $30, but a good one will run around $70. Set it up on a tripod facing the side of the house. Set it out at night and in the morning you will have a video of where they are entering. Just move the camera to different sides of the house until you find them. Set the camera on maximum sensitivity. The closer you set it to the side of the house, the better it will work, so you may need to take two or three nights for each side of the house. The mice or rats will be heading to the ground, so make sure that the camera points so that you can see where the house meets the ground.
