Is it a problem having slugs in my compost bin?

No, they're not a problem as far as I know. A compost bin should contain a lot of creatures that break down the vegetable matter and make it into compost, and that's what the slugs are doing. I actually chuck any slugs I find into my compo bin as I can't bear to kill them lol

I heard they dont leave the bin Numberone, they have all the food they need in there, Also there leaving our plants alone :)
Sid.. I do that as well, throw the slugs in there.. Now snails! there a different kettle of fish LOL.

No the slugs, snails, worm etc are all good workers in your compost bin... You're giving them an 'all you can eat' buffet which you keep topping up so they are very happy beings.

I chuck snails in my compost bin too - might as well put them to work!

Of course the alternative is to feed them to your, or your neighbour's hens...

Slugs etc not a problem in themselves but sometimes if you have masses and masses of them it can be because you have too much green stuff ( peelings, etc) in your bin and you need to balance the compost with more brown stuff ( paper, cardboard, etc.)
