Insert traps are a great way to rid your purple martin houses of Sparrows and Starlings. This NEW Universal Insert Trap features an oval opening that not only can be used on a wide variety of martin housing due to its small size but also can be used with Starling Resistant Entrance Holes (SREH).
Works great with most Trio houses,
(except the Grandpa/Safety System and the Wade), Coates houses, Lonestar houses, the Troyer T-14, and just about any wooden house with round, crescent or other sreh entrances, can use this trap.
The Oval Universal Sparrow trap is designed to fit inside housing whose inside measurements are no smaller than 5 1/4" high x 4 3/4" wide x 4 3/4 " deep with an entrance hole aligned at 2 3/8". PLEASE measure compartment interior to assure that this trap will fit.
The Universal Sparrow Trap is an easy to operate insert trap that humanely catches non-native pest birds but will also catch native birds so close monitoring is essential.
