Compost bin flies
« on: May 29, 2021, 09:51 »
I've got a compost bin for all the uncooked plant material kitchen waste. It works well, and is effectively a hot box type bin in an old wheelie bin. However, Every time I go near it there's a swarm of little fruit flies in there. They're about 2-3mm long and there are hundreds of them. They don't taste good.

Any ideas on how to stop them, do I need to change what I'm putting in the bin?

Thanks a lot.

Is there any drainage from the wheelie bin?  Fruit flies / fungus gnats often appear if the medium is too wet.  But flies in a compost bin aren't that unusual.
I try to take one day at a time, but sometimes several days all attack me at once...

Hi Gus

Like it or not, those fruit flies (and other insects and crawlies, and their larvae) are actually working for you to break down your compost.  As long as it isn't something that can sting or bite you (bees, ants), can you work around them? Most of us now have masks laying about, you can slip a mask on when you are making a "deposit".

Next to my compost pile, I keep a covered bin with chopped leaves and grass in it (my chopped mixed greens and browns to add in).  When I place fresh kitchen material on my pile, I also toss some of the greens and browns over the fresh stuff, it doesn't eliminate flies, but it keeps the numbers manageable. This should work in your wheelie bin too.

I also agree with checking that drainage as Yorkie said.
