I'm not sure what others do but I just tossed some pecan that was just as you described. To answer your question, I don't think any bugs can survive a good fire.
I would probably use it for campfire or fire ring. I would even use it to cook with if I could preheat the wood hot enough inside the FB. But if the wood has that white look to it I would pass on cooking with it. But if you are in a pinch it will burn

It doesn't look white at all. Got a few pieces with some algae looking green, but I think that's from moisture under the bark. The bark is easily separating too. Even after it got rained on the other day, 1 day of sunshine and the bark on the ground is cracking like dry bones.
Yeah mostly surface bugs... got a few logs that look like they have been hit with a few tunnels but nothing major. I'm just being extra careful since I'm cooking with it and because I don't want bug infested wood around my house.
I ended up keeping most of the wood. I sprayed the pieces that had lots of little white bugs/ants and then got rid of those pieces. All in all it worked out good.. it's a lot of wood at least it felt like a lot when I was stacking it all. Most of them are big logs. Once split it will be even more...and for only $30... $45 if you count the gas I put in my neighbors truck to go get it...Chipped off the bark and used it for mulch on the side of the house and stacked up the wood. It's nice and dry, burns good. Thinking about building an overhang to keep the rain off but not sure if I really need it.
