(NSFK) Horrifically disgusting yarn disaster!!! What the heck?!?!

So I got this beautiful yarn at a yard sale. Varigated grey and electric blue 1 ply. So so soft. Has to be some kind of nice wool. I've been working on a  sweater from it, got about five inches with a cool design. I left it outside this morning, came back this afternoon to keep working on it. I noticed there were flies buzzing around it like crazy. I'm like "hmm weird guys", look at my project a bit closer and OOOOOOH MY GOSH THERES FLY EGGS ALL THROUGH IT!!

They're worse than in the picture. All through it! Right up by the needles where I was working too!!!

Ugh

I put a Not Safe For Knitters (NSFK) in the subject of this thread because yuck!  

That's so incredibly sad.  I really hope that this was something that came from the outside and not something wrong with the yarn that was activated by the dew from being outside?  Maybe the rest could go into quarantine?  

That it's pretty makes it even sadder.  

So I take a look at the ball of yarn...

They made a point to burrow into it and dump eggs too!!! What the heck??? WHY! Is this a wool/ animal fiber thing? Maybe something weird the original person  "treated" it with??
I am usually pretty stoic about these kind of things but I'm so revulsed that I'm in tears...I'm probably going to burn it just for the peace of mind!

I swear they weren't there until this afternoon. Literally like four hours outside, midday partial shade, on dry grass. I wonder if the previous owners spilt something weird on the ball, like grease or They weren't crunchy people so I don't suspect anything outrageous...

I am sorry this happened, oh my.

My suggestion would be to wash that beautiful yarn in cold water to try to get rid of the eggs.

When it is really good and dry put everything into a plastic bag with lots of alcohol-soaked cotton balls, seal the bag well and wait for the eggs to hatch.

This might only need to stay sealed for a day, though I would wait longer.

Anne: I don't think I can bear to salvage it. There will be more yarn. There will be more time for projects. I just can't even...it really got to me...

UPDATE so I ran out to get it and dissect it to see just how bad it was. It started sprinkling so disregard the water droplets. This is as far as I could handle...I would say theres a good tablespoon overall D:

Holy cow that is AWFUL. So many!!! I understand just wanting to get rid of it. If you think there’s any chance you might change your mind, you could seal it in a bag and stick it into the freezer, to put it into a time out for later… But I wouldn’t blame you for dumping it (or setting it on fire).

I torched it, Juniper. Oh it was a mess. And the dang things were flying around trying to land/landing and checking out the parts that weren't on fire! What in the world is on it that's so irresistible? Find some roadkill for gosh sakes!

Better than get it all done and wear the sweater out in the public and be the fly magnet! Maybe the yarn has blood stains or something.
