A device for the detection of rodents comprises a generally hollow container having an aperture to allow entry into the container and exit from the container by a rodent and an indicator to indicate that a rodent has exited the container through the aperture. Preferably the indicator comprises a flexible barrier located across the aperture. At least part of this flexible barrier is capable of being displaced from a position in the interior of the container to a position on the exterior of the container by the movement of a rodent through the aperture from the interior to the exterior of the container. The device makes it possible to detect rodent infestation and is able to provide positive evidence of a rodent having been present inside the container.
