I have just found this for you.
Feeding your Tarantula
Tarantulas will eat crickets, moths, beetle larvae (meal worms or superworms), houseflies and cockroaches. The rule of thumb is not to feed your tarantula a prey item that is larger than it is and usually approximately half its size. Although, some tarantulas are aggressive eaters and will eat prey as large as they are. You should feed your tarantula prey items that you are positive have not been contaminated with pesticides, for this reason some people prefer to feed their tarantulas purchased prey items like crickets and meal worms. Offer your pet 1 to 3 prey items two to three times a week, depending on how big your tarantula is and how much it can eat at one time. Some larger tarantulas will accept live baby rodents, like mice. Care must be taken to remove any prey items that have not been eaten within 24 hours or so, uneaten prey items can be quite stressful for the tarantula, and have been known to cause damage and even kill tarantulas if left too long.
Drinking Water:
Tarantulas do require a source of drinking water that you can provide by using any shallow container filled with
water. Small pill vial lids work well for spiderlings and small tarantulas. Shallow bowls, plastic food container lids work for larger tarantulas. You can also supply water by misting water on the substrate and the sides of the enclosure. Care should be taken to keep a minimum of one moist corner within the enclosure, and gauging the amount of misting to the humidity requirements of your particular tarantula.
