What do you guys think about "mega-mites"? Supposedly they feed on snake mites, and die off as soon as all of them have been eaten. It is said on their website (i found the link on rtb, not sure what it is but i'll post if if anyone wants me too...) that you can see the snake mites being eaten right before your very eyes.
I don't think I would release any form of parasite into my snake's cage, whether it be mega-mites or super-duper-mega-ticks. "They" say it works, though.
