Model 502 is new and improved with input from wildlife specialists. This trap collapses to just half an inch thick for easy transporting or storage and can catch and hold 15 or more pigeons at a time. This trap features two trap doors with swinging bobs to allow pigeons to enter the trap but not exit. Bait your target area with food and a water for several days before you introduce the trap. This trap measures 35L x 16W x 8H" when deployed and 35L x 24W x 1/2H when collapsed for storage or transportation.
