crawfish within elevated sand mound

[enviroman13]

Has anyone had problems with crawfish within elevated sand mounds and any solution on eliminating this issue?

I think your answer is a dish called Crawfish etoufee!

I assume they are burrowing into your mound?  Is this causing your mound to spring a leak?  I've seen horses dig and roll in mound systems but not crawfish.  a Picture of your crawdad infestation/destruction would be great!
