About the snare and setup
Before you set up a snare for capture, you should practice releasing the snare. Put a pair of leather gloves in the opening and pull it tight. I grasp the cable ½ inch in front of the locking slide. Wiggling it while trying to push it straight into the hole will loosen the snare. You can then grasp the sliding lock and pull it open. You can also grab the lock with a pair of pliers to pull it open. Practice first!
The snare has been designed for iguanas with a swivel that allows them to spin and twist as much as they want without tangling up the works. The snare is preloaded, that means it is formed in a way that makes it close easily.
Location of the snare
If you’re thinking about catching iguanas you have probably been watching them for quite a while. In many areas they have a path that they almost always follow. The snare should be centered in this path. For example, I have a concrete seawall that is 13 inches wide. When the iguanas are moving, they almost always stay on the seawall. 99% of the time they walk straight into the snare centered on the seawall. You know the places they always travel best, the hole in the fence, between those two rocks?
The bottom of the snare loop should be about 2 inches above the ground. When iguanas move, they travel with their head up. If they manage to step through the loop they will likely be caught in front of the rear legs. The snare is preloaded. That means it wants to close just by being touched. With every movement it continues to close and it won’t open. Try it with your hand.
The stake is only 2 bucks in the fencing department at local home centers and hardware stores. Lowes calls then a fence u-post. I use the four foot length item number 92063. You will need a short piece of wire to help adjust the position and height of the snare.
