I've just been out to my compost bin and it's full of ants, including flying ants and eggs. Do I have a serious problem or can I just leave it?
You can leave it if you like, but it does suggest that the compost bin is too dry.
Thanks, I'll try that. Although I did water somewhat when I added a 'brown' layer (which had to be shredded newspaper as I'd run out of leaves and old compost out of pots) about a month ago - but maybe it was not enough. As the bin has only just reached a point where I can use the first lot (it's less than 18 months since I started it), I was loathe to have to remove all the stuff and start again!
