Lately I have been noticing some kind of worms or larvae in my compost when I go out to add to it and turn it over. I can even hear these things making a smacking noise (so gross) and it almost smells like sewer. They're about a half to three quarters of an inch long and a tan color. They just showed up one day. Is this right?

Compost should not stink, it's probably too wet with too much green material.
Turn the compost pile and add more brown material (leaves). Should be 2 to 3 times brown material to green.

Craw garden,
You're probably right. I've noticed it is pretty wet. I'll try the leaves because I have enough of them for sure. Thank you for the tip. I'll do that.

Sounds like black soldier fly larvae.They are completely beneficial (but gross
looking, I admit) and like a very wet compost. They are very good at eating fresh kitchen waste. I first noticed them after getting large amounts of coffee grounds, but now they are yearly.
