Bat Cone and Procone Installation 

Thank you for the demo.

Hello, I'm from Brazil, could you share the main dimensions of the bat trap, (length, smaller and larger diameter,....), we don't have it for sale here in Brazil and I intend to build my own with pvc pipe.

Well, it's worth a try if I can find the entrance point. Hopefully it's not the ridge vent. I got them out 20 years ago, now they're back. I really need some type of noxious repellent.

Use an empty caulk tube with the end cut fully off. Cut 8 inches of copper mesh. Wrap around tube like a chute and secure mesh with duct tape.

I guess I don't see why a Bat could not get back through that vent. Not explained.
