Is the remaining sawdust and dead insect in perches after baking harmful?

[ZY28]

So, I just went out a pickup some mapple branches to make natural perches. I had to get the bark of since some mapple's bark is toxic to birds. By doing so, I saw some tunnels filled with sawdust. I saw on line that by washing, soaking and then baking the branches will kill anything alive and become safe for parrots. But the dead insect and tunel fill with sawdust will remain in there. Is that harmful for parrots? I suspect the tunnels are made by Wood boring beetles and they only eat sapwood.

I wouldn't be worried about it myself.
