I just thought of this too, might be helpful info: I almost never feed the worms fruit. Citrus is a definite never food in my bin, but I also very rarely feed anything else that's very sweet. Sometimes they get a mushy apple or tomato, but it's not a regular thing. They get a variety of veggies, but not much fruit.

Looks to be a Black Soldier Fly.

Hard to tell from the photo but Black Soldier flies have white rear legs (see link below)

Here is a link that might be useful: Identifying Black Soldier Flies

Kinda late in the year. BSFLs are dormant in NC now.
I have a wash tub full of them.
Sleeping like babys.

Photo is fuzzy. And didn't know the location of the poster. Lat year I've had BSF hatch out all winter from the bins that I brought inside.

Inside the house or heated garage?
My garage has no heat so things get real slow down there.
When the BSFs are hatching, say August, September, I would find a dozen on the windows in the garage. None now.

Inside house.

Looks like a Black Soldier fly to me, too, but all the ones I've seen are much larger than fruit flies. If they're inside an indoor worm bin then they were just hatching. If they were hatching you should have noticed larvae in your bin - hard to miss those.

Sorry, not a solder fly.

Hi all,

Thanks for trying to ID the little critters. Sorry the photo is fuzzy. It was in macro mode and the things are so little I couldn't get a clear shot.

They don't have white legs, and they don't get any bigger than a fruit fly. I'm quite sure they're not a soldier fly. I haven't seen any of the telltale larvae in the bin and they're not getting to the size of a soldier fly.

ANY help would be greatly appreciated. If I can't get them under control I have to scrap the worm bin idea until it can be kept in a garage someday.

jwilson gardener if you could include with your picture an object of known size, a penny, a pen cap, a ruler, an M&M it might help. Although they do not have the white legs of BSLF they are acting like them by flooding the windows.

Can you either open the bin and the garage doors or drag the unit outside? At the same time open all the kitchen windows to set everyone free.

Keep the bin outside until the situation stabalizes.

You may of just discovered a composter better than even BSFL. Maybe you should be capturing them and selling them?
