In the past I have been asked by customers if a wormery can be kept inside.
Below is my response to a forum question posted by woofwoof in 2009;
“hi i am a keen angler but i live in a flat with no garden could i start a small wormery indoors, do they smell ?”
Wormeries are a great way of breeding a supply of worms for fishing and getting rid of some kitchen waste! The most commonly used worm in fishing is the Dendrobeana it also happens to be an extremely good composting worm, although “Tiger worms” are often claimed to be sold on websites for composting it is actually Dendrobaena you are likely to be supplied with.
If a wormery is running properly you will get no smell, any offensive smell from a wormery is a clear indication that things are going wrong, from this point you are safe in keeping one indoors, HOWEVER, the waste that is put in for the worms should ideally be high in vegetable and fruit waste, as this decomposes it will inevitably attract the tiny fruit fly and this could be a real nuisance so from this point it may not be such a good idea indoors, whatever the claims, there are no wormeries that exclude access to this fly, it can be controlled to a certain extent but during the warmer months it will be present. If possible I would keep it outdoors, even on a balcony or similar.
We supply a smaller wormery called the Tumbleweed and you can find it on our website under fishing mail order called “The worm breeder” it is supplied complete with the necessary bedding and choice of Dendrobaena worms and would usually be fed on the waste veg and fruit BUT there is an alternative, instead of using waste fruit and veg you could keep topping it up with the specially prepared bedding, this would not attract fruit fly, would feed the worms but, although low cost, would need to be purchased from us.
I hope this has been of some use.
