A rodent trap structured for capturing one or more rodents as a piece of bait is being consumed within the trap. Slidably mating, telescopically extendable upper and lower inverted and upright cup-shaped members, respectively, define a closed interior volume into which a rodent may enter through an entrance hole formed through a side wall of the lower member when the upper member is held in an armed position above the bottom of the lower housing. To hold the upper member in the armed position, a slender elongated trip rod of one embodiment downwardly extends from a central point of the top of the upper member, to be supported on a rigid piece of bait held above the bottom between uniquely configured spaced bait posts. These bait posts are connected to and upwardly extend into the interior volume from the bottom of the lower member. When so supported by the trip rod on the rigid bait, the upper member will only drop by gravity from the armed position to a closed position after sufficient bait is consumed by rodent to allow the remaining bait portion to pass downward between the bait posts, closing the entrance holes and capturing all rodents within the device at that time. The trap is preferably transparent for viewing of captured prey before disposal and includes evenly spaced entrance holes facing in all directions.

A roach or rodent trap structured for capturing one or more roaches or rodents as a piece of bait is being consumed within the trap. Slidably mating, telescopically extendable upper and lower generally cup-shaped members define a closed interior volume into which a roach or rodent may enter through a hole formed through a side wall of the lower member when the upper member is held in an armed position above the bottom of the lower housing. To hold the upper member in the armed position, a slender elongated trip rod downwardly extends from a central point of the top of the upper member, to be supported on a rigid piece of bait held above the bottom within a horizontal bait aperture of a bait table. The bait table is connected to and upwardly extends into the interior volume from the bottom of the lower member. When so supported by the trip rod on the rigid bait, the upper member will only drop by gravity from the armed position to a closed position after sufficient bait is consumed by roach or rodent to allow the remaining bait portion to pass through the bait aperture then closing the entrance holes and capturing all roaches or rodents within the device at that time. The trap is preferably transparent for viewing of captured prey before disposal.
