Yeah we've seen plenty of that (bad tarantula!). Though, 3 inches is still kind of a sling in my book.they don't burrow? tell that to my 3 inch chaco who's dug a burrow under her hide all the way down to the bottom back corner. ;P
By the way, I notice tarantulas getting a lot more into burrowing when my house is cold. If you don't want the burrowing, you might consider temperature as a possible factor.
