I have a boring bug in my fig branches causing sawdust to fall onto leaves. The branches have a hole in the middle and something is eating the wood. What is it and what can I spray to stop this?

It is hard to say what type of tree borer it is without actually seeing it to identify it.
This is a serious condition and it is likely that the tree will be completely girdled and be killed.
Phryneta spinator, stem bore beetle is a likely culprit.
Here is a few links for you with some more information and possible treatment and control.
