· Worm bins can be kept inside and outside. When I had a garage I kept them in there, but when I moved I kept them in the kitchen closet. The general rule is if you are cold, so are they. I put them out on the deck early spring when it was getting warmer (don’t leave them in the direct sun), and will bring them back inside when it starts getting cold. It doesn’t smell, and you only get fruit flies during f.f. season if you aren’t careful.
· If it does start to smell, lay off on the food for a while and add “brown” (paper, leaves). That will help balance the bin's contents. Just remember that it needs balance- give them a variety of food, and keep it moist but not mushy and drippy (that’s what I call worm diarrhea!). If you overfeed them, it will bottleneck the process.
· If you want to use the castings for your garden or house plants, stop feeding them for a while so that they can go through the food that’s already in there thoroughly. It can take about 3 months sometimes to go through everything.
· Some items they love are fruit, veggies, stale rice/pasta/bread, coffee grounds, tea (take staples out of the bags!), used napkins, paper towels, and my favorite, used coffee cups! They will eat all of the paper and leave the wax lining, so you will have to pull that out when they are done. (I find it fascinating, but maybe I’m just weird!). Don’t give them fats, dairy, meat, or anything cooked. Throw all of that stuff in your yard waste bin.
· One more thing I forgot to add, it’s not the worms that actually eat the food. The food breaks down with the help of microbes, and it’s the microbes that the worms eat. Nice little cycle!
