Black fly larvae in my bin NEW
by: Earl compton

The larvae entered my bin with a vengeance, I hate those nasty things!! Every couple days I would pick out all I could find. When I was at my wits end at about a month, I went to my bin and the larvae were GONE !! Don’t know where they went, don’t care as long as they don’t come back. I’m going to add some Dolomite n keep my fingers crossed. Been 2 weeks now and no larvae.. I’m a happy camper!!!

Hello Earl,

that sounds like "Black soldier fly maggots."

Have a look at the two articles about the BSF maggots.

You might have to start your worm farm from scratch again if you can't get rid of the vast majority of the BSF maggots. If the maggots are left undisturbed the worm bedding will most likely become soggy and smelly and the worms will either have fled towards the lower parts of your bin or even left the bin for good.

The URL's for the BSF articles are as follows:


I hope you come right.

If you have any further questions please let me know.

Kind regards
