Can't figure out why my pet toads keep dying, Please Help!!

[Cliygh and Mia 2]

There is a woods behind my house and i'll often go and collect
various bugs such as ants, spiders, earthworms, potato bugs, etc and during the winter i would
buy meal/super worms.

Ahh, that's it. Wild-caught prey items almost always have parasites, and if you gave them that every spring or summer, that would have loaded them with harmful parasites
