To clarify, the Tomahawk One Way Door Excluder for Squirrels and Rats - Model E50 is not a trap. This product is a one way door exclusion device. It is meant to let animals exit a structure and then prevents them from going back in the same way. If you want a product similar to the way this one works but capable of actually trapping the animal you will need the Tomahawk One Way Excluder with Rear Door for Squirrels/Rats - E50D. As to how easy the device is to remove from the structure, this will depend entirely on what materials you choose to use to secure it to a building. If you use Liquid Nails it will be very hard to remove. On the other hand if you use regular nails or screws you could simply remove the nails and the device can be moved. Professional pest control operators usually secure the traps with screws.
