Ants in compost

I've got a neglected 'dalek' compost bin, full, very dry, with a colony of red ants.  Clearly I need to start again, and be more diligent, but what do I do with the current contents?  Apart from the red ants, it's mostly spent compost.  Can I spread it as a mulch - will I be over-run with red ants, and if so, how do I get rid of them first???



  • if you disturb the ants and dont leave it alone, they will move on

  • So, Discodave, do you mean I should turn it, or give it a poke with a big stick or something?

  • yes, give it a turn about once a week. 

  • I'll give it a go.  Thanks.

    You will need to add some water to that compost bin, for the action of rotting to restart the contents need to be moist and damp. You cannot make compost with dry ingredients. This will also move the ants along, they don't like being wet.


  • Thank you.  I was hoping to have a magic formula to get rid of the existing mess once and for all so that I can start again properly with the new season.  Perhaps a second Dalek is the answer.

    If you have got spent compost-spread it on the bedsimage-the ants will just clear off.image

    Ants are usually a sign it is too dryimage

    You need to keep compost bins moist for the rotting process to begin and continue.

    Just watering it will make the ants move.   If you add a small bottle of essential oil of cloves to a 10 litre can of water and water that on after the first wetting, the ants will not come back.  They can't stand the smell.

  • I start compost in an old fashion wooden slatted bin then transfer to the 'dalek', this year I had a colony of ants which improved the structure no end - very fine, fully composted perfect for seeds.

  • Thanks everybody.  Off now to get cracking on that Dalek!
