Hi Adrienne You are right that the insect bodies are left in treated items, and they can be a food source/attractant for dermestids.
The wings may be alate wings. Reproductive termites have two pairs of wings that they shed following colonising flights. Do you know what sort of termites were in the building? What treatment was carried out?
