The Tomahawk Repeating Reptile Trap - Model 450 can be used on land or in the water.
Unfortunately, the Tomahawk Repeating Reptile Trap - Model 450 is the only repeating trap we offer for reptiles.
Since snakes only eat live prey there really is not a way to use a live bait in the trap like the Tomahawk Repeating Reptile Trap - Model 450.
The Tomahawk Repeating Reptile Trap - Model 450 cage measures 32 inch L x 18 inch W x 9 inch H. The trap doors are 14 inch W x 7 inch H. So it would depend on the size of the actual iguana.
The spring rods on the side of the Tomahawk Repeating Reptile Trap - Model 450 are for latching the doors into place. If you have troubleshooting questions for use, you can contact the technical team at Tomahawk directly at 715-356-4600.
