No update yet. The first year was a bust. I think they might have been a little hidden in the trees. I plan to move some to a more open area and try again this year.
It depends on how many traps you want to make. However, you can make 6 traps out of: 1- 15/32 4x8 sheet of plywood, 1- 11/32 4x8 sheet of plywood, 1- 2x4 x 8’-0” stud, 1- 12” x 10’-0” roll of aluminum sheet metal. You will also need a gallon of primer and a gallon of paint.
