Thank you for your response to my post Quarter Acre! I purchased the Z trap with 1/2 inch squares from Reel Texas Outdoors and have been putting a mesh bag with dog food in it with excellent results on small BG. I agree with you that the trap needs to have the 1/2 inch squares to catch all sizes. My question is the 1/2 inch width of the K trap opening large enough to allow adult BG to enter the trap?
