Our funnel traps are designed for snakes. They work by having the start of the trap look like a hiding place. The opening is fairly large. The space through out the middle of the trap gets smaller. So the snake cant move backwards and it will be stuck in the trap. The funnel is not sun proof, if you leave the trap in the sun it will need coverage. Or put it in a shady spot so the snake doesn’t get burnt. This trap is safe and non-harmful to the animal or user.
