Immediate warning to yarn users!
Knitpicks has recently been sending out yarn infested with carpet beetles. Apparently one of their warehouses has an active infestation.
They have shut the warehouse down for now, but if you have recent yarn from them in your stash in may be infested!
Knitpicks is not currently informing their customer base of this issue (pretty standard for them, unfortunately), so word of mouth is necessary.
Here's some more info from Reddit.
On Reddit one person that recently received an infested order is reporting that it came from Columbus, Ohio. So that could be where the infested warehouse is.
Suggested actions are to freeze your yarn for two weeks at 0F, or 72 hours of you can get your freezer colder.
You can also cook your yarn in the oven at 200F.
And, as this summer, black bag your yarn and leave it in a hot car for two weeks to cook.
More information!
Sadly, not good news.
Given the life cycle of carpet beetles, and the fact that at least one person has confirmed the eggs hatched in their yarn only within the last few days, the eggs had to have been laid roughly two weeks ago. So the infestation is older than two weeks at least.
The knitpicks team is currently on Reddit claiming they know nothing about this and will look into it. But other people on Reddit have already said they contacted knitpicks at least a week ago and were told the warehouse was being shut down for inspection. So, at the moment, the private equity firm that owns knitpicks is trying to do damage control. It's unknown if anything will actually be done.
