well after some instructions from our old friend coach i have finished 2 easy to build perch traps. all it takes is a roll of plastic hardware cloth and 400 4" zipties. i built mine in about 2 hours each. they are alot sturdier that i thought they would be and the price for both traps was about $20. all the commercial traps that i looked at were anywhere from $30 up to $85 so these traps wont break the bank. i know that they're not too pretty but i dont think the perch will mind. the hardware cloth and zipties were bought at lowes. they each measure 18x18 inches. hope this ends my perch catching problems for the summer.
