You can print out page 9 of this pdf http://ir.library.oregonstate.edu/xmlui/bitstream/handle/1957/23949/em9034.pdf and stick it near your bin. Just a list alone is not so useful as it won't give the reasons.
Food that is okay.
Fruit and vegetable scraps and peels. Potatoes
peels are okay, but worms tend to avoid them
• Eggshells or other source of grit (see page 8).
These should be ground or pulverized.
• Coffee grounds, filters, and tea bags with
staples removed. You can mix them into the
worm bin at any time.
• Plain cereal, bread, and pasta. Use small
amounts only, as they tend to clump up. Be
sure to wet them first.
• Dryer lint (natural fibers only, such as cotton,
linen, or wool). Lint provides the “fabric” for
Food items that are NOT acceptable
Though your worms will eat just about any
organic matter, some types of food may entice
undesirable insects and animals to live in the
worm bin, too. The foods in the list below are not
appropriate to feed the worms because they attract
pests, can be toxic to worms, or create unpleasant
• Meat, poultry, or fish (bones, skin, or
drippings). These develop odors and easily
attract other pests.
• Oils (such as butter, salad dressing, or
mayonnaise). These smother worms (they
breathe through their skin).
• Dairy products. These products may cause
anaerobic conditions and odors.
• Highly acidic or spicy foods, such as citrus
(especially peels) or onions. These may
produce acidic conditions and may be toxic to
• Pet feces. Feces can contain large quantities of
pests that are not beneficial to worms or to the
final compost product.
The guideline for vermicomposting is: When in
doubt, leave it out
