>>55652Something to consider is the homemade conibox. It is a conibear trap size 110 in a wooden box with a wooden trigger pan and bait in the back. Pic related. When done its about the size of a shoebox. If you put it on your roof you'll only get the squirrels, birds are too small and light and will pass through.
Try things like peanut butter or corn in the back. When they trip the pan they are dispatched, no worrying about escapees.
Only thing that is a drawback to me bout these is I eat squirrel a lot so I need to be home when the traps fire or the meat spoils. But even when it spoils I still skin the hides for training my dogs and trade the tails to Mepp's fishing lure company for free trout jigs.
