Anyone building in mud, needs to know about termites...
This is an Aus site though, and I dunno if termites live in cold places... so maybe this doesn't apply over there????
Anyway - this is a good site for those building with mud, just so's you know what you are looking for... and what they do to the earth (manic little contributors to soil erosion probs!)... and how to deal with them.
