I don't know if this is the right section to post this in, so if it isn't, my apologies.
Can you keep mealworms in the hamster's cage? I saw that some people do that and don't have a problem with it, but one time I saw that the mealworms started to attract ants. I always make sure the worms get consumed and there aren't any left overs because I'm scared it will attract ants. However, some people simply leave the worms in the hamster's bedding and it's fine.
Thanks!
