it depends on the size of the fireplace in comparison to the size of the moth. It may not be intuitive, but actually the SMALLER the moth, the more likely it is to be able to eat an entire fireplace. Most moth websites don't recommend this as part of a healthy diet though, as fireplaces are often seen as carcinongenic (bad for you).
One more thing, if you want to protect against moths eating fireplaces (can be costly), why not take up fireplace insurance that covers it?
Hope this helps,
