Abstract: An animal trap includes: a bait, a support, and an elastic band, wherein in a set state the support supports the elastic band in an expanded state, and wherein removal, consumption or destruction of the bait by an animal: causes the elastic band to contract around the animal to kill the animal; or causes the elastic band to drive a kill mechanism to kill the animal. Animal traps may be formed substantially or entirely of biodegradable materials. Animal traps may be adapted for aerial distribution. A trap dispenser may dispense traps as they are triggered.

Abstract: An animal trap may include a source of compressed gas; a trigger mechanism configured to be actuated by an animal, and a kill mechanism powered by compressed gas. The trap may include two or more trigger valves connected in series. At least one trigger valve may include an opening, a valve seat surrounding the opening, a valve member having a sealing surface, and an O-ring arranged to seal between the sealing surface and the valve seat. One or more flow paths may allow gas to flow along at least part of an internal periphery of the O-ring. The trigger may include a trigger rod extending in a rest position from a mount at or near a first end thereof. The trigger rod may be mounted for pivoting movement about the mount, and may have two rotational degrees of freedom. Pivoting movement of the trigger rod in any direction away from the rest position may result in actuation of the trigger.

Abstract: An animal trap is powered by compressed gas and includes a trigger mechanism and kill mechanism. The trap is preferably self-resetting. A variety of sources of compressed gas may be used, and different kill mechanisms may also be used. The trap is particularly suited to applications where low-maintenance traps are required, because it uses a simple, reliable mechanism which can kill a number of animals over a long period of time without requiring maintenance or manual resetting.
