Abstract
Abstract An animal trap for vermin has a container with an end wall containing an opening. A spring closed door within the container seals the opening when bait, fixed behind the door, is attacked. The door may be held open by link members connected between the end wall and the door, the link members being joined by a hard bait so that the devouring of the bait releases the link members and the door springs closed.
