Honestly I wouldnt suggest feeding them crickets from outside because you dont know where theyve been. Your best bet is to get them from a pet store that sells them. Those are the best. Also superworms are really good for them and they love them. I feed mine one every few days but their diest is mostly crickets. What kind did you buy?I bought one as an impulse buy at a bug fair for ten dollars didn't buy crickets because then those would be pets too. I fed the T a cricket from outside(this was a week ago) and I assumed this was safe because these crickets seem to happily breed and feed so you hear them outside at night. Thankfully the tarantula seems okay after eating. I ended buying a little cage and 9 crickets today threw in bits of food and hopefully these aren't dirty and kill the tarantula after it deals with one of them.
