Abstract: An industrial animal trap is provided to effectively, continually, and rapidly exterminate rodents, pigeons, and other animal pests in an efficient and safe manner. The animal trap has a feeding chamber, a killing chamber, and an optional discharge chamber, which are separated by moveable walls.

Abstract: A rodent killing device is provided with a plurality of units of feeding and killing chambers, with each feeding chamber positioned directly above a killing chamber, so that the floor of the feeding chamber also forms the ceiling of the killing chamber. The feeding chamber attracts a rodent by bait, which then becomes entrapped within the feeding chamber, whence it is transmitted to the killing chamber by sliding the floor of the feeding chamber outwardly. The killing chamber destroys the rodent by a plurality of spikes impaling the rodent, and then the killed rodent is deposited in a container for subsequent removal. The killing of the rodent is done in a separate chamber so that no leftovers from the rodent or any ill smell is allowed to permeate into the feeding chamber, so that subsequent rodents approaching the feeding chamber are not discouraged from entering into the interior.
