I've been composting with worms awhile now and believe I have some good advice for you:
1) if you are using the active compost method, you can't use worms. Red wiggler Worms survive from 40-95°Fahrenheit (4-35°Celsius), but the optimum temp is from 60-77°F (16-25°C). If you will be having a lot of waste and want to use worms to compost with, you have a couple options:
A) use bokashi composting first (you can compost everything, including meat, dairy, and oils with this method. It is an anaerobic method, meaning you can use an airtight container. After the bokashi compost bucket is full, either bury the pickled waste in your garden or feed a little at a time to your worms. Over feeding the worms is bad and can overheat the bin. There are many sites on bokashi composting if you google it.
B) the second method if you really want to have an active pile is to wait until the hot composting process is complete. I have a compost pile that has yard waste and horse manure (worms delicacy) right now that is 154°F (68°C). That's almost twice what the worms can survive in. Let the "hot" process complete, then add the ingredients to your worm bin. Hot composting is great to do prior to worm composting because it kills any diseases, pathogens, and weed seeds. Horses only digest about 1/4 of what they eat so many weed seeds escape.
* if you'd rather only use worms, you will need to build a compost pit (which you can insulate with straw in the winter) or you will need to put together a bin for them (wood ones are better than plastic because the aeration provided). You don't want to use garbage cans if you can help it because they will be too deep for the worms. If you have any questions, let me know and I'll be happy to help out any way I can.
