The crickets I get are very small. So small, that some are able to get through the screen top, of my BP's cage. That should give you an idea of how small of crickets I'm talking about. I'm not particulary worried about them chewing up my BP, since they are so tiny, and their jaws can't penetrate my skin, so I highly doubt that they can penetrate my BP's skin. We're talking really tiny ones, that occasionally get's in his cage. But I don't no if they can transfer any form of deseases, and that is my main concern. And as some of you stated, it could be a possibility, so I will fix this problem. Thanks for the help guys.
