I noticed my fruit bowl today and thought not many people have balls of yarn mixed with their apples and oranges. The balls of yarn were there waiting to go into my freezer. The reason: To stop moths from multiplying and eating holes in my wool things. To prevent that: do the following: Put the wool item in the freezer for two days. Take it out for two days. Put it back into the freezer for two more days. The time out allows any eggs to hatch and the freezer zaps them with the second incarceration. This is serious advice used by serious textile people. When they bring home something, it goes straight into the freezer.
I noticed a moth flying around when I was at the computer the other day. I ordered moth traps immediately. I set one up near some other wool yarn that I was suspicious of.
I looked tonight and saw I’d caught one. It’s the larvae that do the harm but flying moths make eggs which make larvae and then turn into more moths. Catching the moths stops the cycle.
I have had this moth trap hanging over my closet for a long time and I can see it’s doing its job. What this means is that I haven’t been religious about the freezer treatment. I discovered a couple of wool garments from trips that had a hole or two –or worse—larvae casings! Then they went to the freezer for sure.
