I'll preface this by saying I've done a bunch of research on this forum and scoured the internet and can't find a solution to this problem.
Three years ago I finished a waterfall desk for my daughter from a large slab of Kentucky Coffee Tree. The slab had evidence of insect infestation and the sawmill assured me it had been kiln dried so I thought I was good. All of the holes and channels were filled with epoxy during the manufacturing process. Overall I think this slab sat in my shop for 3-4 months before finishing the desk and bringing it into our house. Never did I see any evidence of live infestation.
About a year ago my daughter mentioned that there was a hole the front edge of the desk. Upon inspection I saw no dust and incorrectly chalked it up to epoxy failure and figured it had just popped out of the hole due to seasonal wood movement.

Fast forward to last night at dinner. She mentions she had noticed a couple more holes. Of course my heart sunk and I immediately inspected the whole thing. I found these other holes. Based on my research I believe they are powder post beetles although I don't see the telltale dust in the hole. My guess is it's been worn away as this is her remote learning desk which she spends 7-8 hrs/day at. All of the exit/entry holes are on the front edge of the slab and all contained within the sapwood (1/2" - 1") from edge.

Looking for help on how to get rid of the beetles but more importantly, should I be worried about the house?
I didn't sleep well last night so any support, suggestions you guys have would be appreciated. I don't mind ripping both edges from the desk and in essence remaking the waterfall to mitigate the active beetles. My bigger concern is about the other wood in the house. One positive I read is powder post beetles tend to stay in hardwoods which hopefully would mean they should stay out of the house structure but there is a lot of other furniture in the house.
Thanks,
Wes
