I had this thought today and started looking around to see if anyone else shared it. Apparently one other person, S. Premena, wrote about the same idea before. You can read his original post here:

The idea is simple, insects (particularly wasps) create nests. Those nests end up as what we commonly refer to as wasp paper. Before we started creating fiberglass batts we used paper for insulation ourselves. The fiberglass batts were better because of the natural voids between the threads (air spaces). These voids make it difficult for temperature to permeate through to the other side of the wall. Wasp nests share very similar attributes. They're made out of paper, but with air pockets which are the nesting holes left behind.

So wouldn't it seem feasible to get a variety of wasp to enter a pre-formed wall and build nests that fill every crevice of that wall. Then at the end of the year, before winter, when they move out you permanently seal up the wall. Now all I need is an entomologist.
