nothing really but look them up so you can find out more. also try to keep insects out of your house which is what thier after. or it could be warmth. try your best.
hope this helps
depending on where you live they could be a poison dart frog or close relative ther of. im not sure how to keep them out of the house but as far as handling them if they are dart frogs dont get any poison in, on, or near open wounds and definately wash after handling them. only touch them if you have to, that is if they are poisin dart frogs
