Don't overfeed your tarantula. Most tarantulas can live on 3-5 crickets a week. Some tarantulas can go a few months without feeding. If you are concerned, a good dealer or knowledgeable keeper will advise you but remember, they will ALWAYS need water. Overfeeding will cause the tarantula’s abdomen to blow up like a balloon, and this could cause it to rupture.
It is not necessary to purchase a large quantity of crickets from your favorite pet store. Your pet can live on two or three crickets about every 12-14 days. Six crickets a month is perfectly fine for an average size tarantula and this is not a hard and fast rule, but rather, general guideline. Overfeeding can lead to problems and is not necessary for a healthy pet. If you feel like feeding six to eight crickets per month that is OK too.
