Being comprised of the stems of plants, straw contains no food value. Bugs see straw as being a lot more like the Sahara Desert than a leftover pizza. Termites, the bane of timber homes, don’t have the right digestive processes to consume straw and can accurately be described as disinterested.
The existence of sound, longstanding strawbale houses has proven that this is true. There are additional non toxic measures that can be taken if concerned. Additionally, the plaster skins on the inside and outside of the walls prevent access for any other pests, unlike tradional wall assemblies.
