My wife (read "Swedish housekeeping standards") is concerned about little things that fly and which she finds occasionally around the house. She thinks they are carpet beetles since she has found a couple under the edges of the wool carpet next to the felt underpad. She has also found a couple in the kitchen and even a couple in the bathroom.
After she found nibbles on a wool coat, we had all the woolen stuff dry-cleaned, oriental rugs cleaned, and the house sprayed. After a while, maybe a year now, we have guests again.
She is suspect of all yarns and when I recently received some yarn from a RCTY, I had to quarantine them for several days in the freezer! [We also have some yarn in the freezer in Sweden recovering from an actual attack in the storage room there.]
Mothballs have horrible smell which doesn't seem to go away. Cedar and lilac/lavendar leaves seem to be short-term unless you sand the cedar to keep fresh oil exposed. In fact both of those seem to me to be marketing gambits in response to the strong smell of moth balls.
Any suggestions please on the care and maintenance of the yarn stash?
Admittedly I am the cause and culprit of the yarn stash but it is all her fault for my enrolling in a weaving class. So now I have two small rigid heddle looms and several stoles for clergy completed and given away. The WIP and hopefully not a UFO is a purse for my wife made from the leftover of a purple stole when I kept weaving to use up the warp after the stole was long enough. bands of purple and a couple of gold thread.
