How to keep Black Soldier Flies out of my dog poop worm bin

by Chris

I recently started composting both dog poop and food waste in an outdoor worm bin. After a few months, I found what I originally thought were maggots in my bin but came to find out they were actually Black Soldier Flies (BSF). In doing some research, I determined that BSF can out compete the worms and should be picked out (something not so pleasant in a bin full of dog poop). The larvae just keep coming back though and so I was wondering how to prevent BSF in my worm bin? The worms seem to be doing fine. Should I just stop worrying about the BSF?

Black soldier fly maggots in a worm farm
by: Stephan

Hello Chris,

although I always support the recycling of dog poop as well as food waste it can sometimes be better to recycle them in separate bins.

BSF are actually attracted by decomposing food waste and not by dog poop. So they usually won't be found inside dog poop worm farms. If left undisturbed Black soldier fly maggots can cause your worms to hide away in deeper parts of your worm farm and they will stop recycling completely. The worm farm will then become soggy and smelly and you might loose your entire worm herd.

So its best to remove the maggots asap if you can. Have a look at the article that I have written a while ago about the subject. You will find it at the following URL

I hope you will be successful. If you have further questions please feel free to contact me.

Kind regards
