RE: Squirrel hunting
When you have some idle time rustle up some snakes, they don't have to be venomous, and set them loose in those pecan trees. Be sure to clear this with the landowner and explain that the snakes are to be left alone to do their job. Squirrels have an inborn fear of snakes, and the snakes will gobble their young as quick as they find them. Do this often since snakes have to rest for a few days between meals. As the snake population climbs the squirrels will begin to thin out from both the fear of them and predation of their young. If this is done early enough in the year the snakes will breed there and produce more to eat the squirrels.
