Looks like you have the right idea.

The USDA-Texas Wildlife Services program has trappers available to remove beavers. The service fee is reasonable. Removing the lodge only makes new beavers build another in a new location, possibly causing more damage to the dam.

Need some help and if in the North Texas area, I can come over with my thermals and take care of the beavers.

When I have beaver problems I call tx predator and hog hunting , they are experts in beaver, hog eradication, and coyote removal, I am very satisfied! 5 stars
