However the first home of any kind I ever knew was constructed of bushes, dried tree branches, card board boxes, and everything tied together with shipping string, had dirt floors, no plumbing, no electricity, and not water.

I did it and went from living in a cardboard box and eating out of dumpsters all the way living in a McMansion and pounding down all the McRibs I ever wanted, even out of season.

with BORIC ACID, cut some 1 inch by 1 inch squares of light cardboard, like shirt cardboard and make a thin SANDWICH out of the paste.Put these around the kitchen and bath, inside of cabinets, very effective.BTW, the "mix some from another pile" thing with fire ants actually doesn't work.

The top layer is essentially cardboard.
