Let the critters remove themselves with the SP50 Squirrel Pack System. Perfect for grey and fox squirrel size animals. It is extremely simple to use and very effective. SP50 consists of one E50 excluder and two SPT50 repeating traps. The repeating traps have one trap door and and an easy release rear door. Attach E50 over the animals den opening with the mounting wings. Slide one of the SPT50 repeating traps over the E50 excluder and hook into place. As critters exit, the excluder will direct them into the repeating trap. To remove captured animals from the property, simply unhook the SPT50 repeating trap and replace it with the other included with this kit.
