    I have been searching for almost an hour thru the forum archives... Cant find a good definite answer. Just cut about 7 Koa blanks. Turned 4 already. Loaded with alive termites... Even inside, when you stop you can see them, I use a few picks to dig them out... These are going to be Polo thropies. So I have to leave a wide rim so they can engrave names etc. I will not hollow it out too much, will make a nice round curve. I'm thinking they will all fit in a big trash can, then I can throw a smoke poison bomb , a fogger. Have to check if the fogger kills termites. Lots of the termites are in the larvae stage, but they are breathing, right? Lol. Any other ideas are greatly appreciated. I kept spraying regular bug killer, what I use for the house and shop, kills roaches etc, the larvae and winged termites that came into contact are dead, but, that does not penetrate the little caves. I will only fill the holes on the rim, as the laser engraver needs a smooth surface, I hope the laser will cut the same thru wood and resin... I will leave all other holes open, and I hope I can kill all termites, I can see a player calling telling me bugs are coming out of the trophy!! Thanks in advance for the help!! Aloha

    You can microwave the bowl, any organism in the wood will quickly heat up and expand and rupture
    from the microwaves heating them up.

    Suggest you do a test with laser on one before doing them all.

    I did some award plates a long time ago. I took one to the person doing the laser engraving to test whether I could finish them first.
    Good thing because using the provided specifications, the laser carriage hit the rim moving the plates around.
    Of course these are the same folks who wanted 9" plates form an 8" diameter log.

    You might want to experiment with different filler materials on a test piece of wood and have the engraver write across them. The contrast in color of the filler and wood is also important. I would be concerned about how epoxy would react to the laser. I think that Inlace resin might be better than epoxy.

    We have mostly subterranean termites here. They can't survive in sunlight and the larvae probably can't survive without the wood being damp.

    So this is where the Termite tool from Oneway might come in handy to slice the little critters!:D

    Bernie beat me to the punch. Great minds thing alike. I would definitely do a test. I have very limited experience with laser engraving but have done a lot of pyrography and you can definitely tell the difference in burn as you go through areas with different materials or hardnesses.

    My niece lives on Oahu HI. She and her husband have lots of thick slab table and counter tops and an equally large problem with bugs in the wood. I emailed her about your problem and her response follows.

    To
    Message body
    We have come up with several solutions for the beetles and termite issues in our tables and counter tops.
    1) In the hardware store there is a specific spray for termites and it comes with a straw so you can spray directly in to their holes. We put the straw directly into their tunnel and spray several times, then put duct tape on top to seal the poison. A few days later we remove the duct tape and wash the wood.
    2) Call Chill Space Billy!!! Take all your infested wood and or furniture and slabs to Chill Space Llc!!!!! Huge freezer warehouse that literally FREEZES the termites and beetles in your wood! Safer than poison and most poisons DO NOT work on the beetle!!!

    Good idea, I better find out the sizes that the laser can handle. One test run before I finish them all. I think I will microwave the little creatures! Thanks for the help!

    Looks like the microwave solution worked, so far... Ended up doing almost 3 minutes each...

    I chase the bug holes with thin CA glue. That gets them every time, and have even left a bug or two 'frozen' in the wood.... Microwaving the wood doesn't always work. I know there is a borax powder you can put in and around powder post beetle holes and it will kill them.

    150 Degrees F for a very short while will kill all known insect species. Because wood is a very good insulator you would need some considerable soak time at temp to penetrate vary thick lumber.

    Looks like the microwave worked. I first did it for one minute each. That didn't do it. I ended up doing 3.10 minutes each. Left them overnight in the shop. Next morning the ants were hard at work carrying out the tasty cooked termite grubs!! I talked to the engraver. He asked me to finish them. Laquer preferably. Once the laser cuts, they fill the indentation with color, and if the wood is raw, the color leaches. I'm attaching 2 pictures. There is enough room to engrave and avoid the holes...

    Another option would be to put them in a vacuum chamber and pull a vacuum for several
    minutes that would also put the little critters down.

    I use to soak my roughouts in alcohol for a couple days and that got rid of the bugs. Microwave might work if you get the wood hot enough, it might damage the wood. I have doubts about vacuum as the worms are sealed in by there swarf. I have used borax on lumber and it seemed to work; A while ago I was sealing the bark on a NE walnut bowl with ca glue. When I came to a worm it smoked, they might have already been dead. I check my bowls that I have in storage occasionally, looking for dust piles.

    When I stop laughing I will reply.
    Power of the swarf. :D

    The power of a vacuum can be extremely forceful on most materials.
    This is what happens when they don't open the vent on a tank car and pump it empty.
    I will advise our mechanical engineers to start making our rail cars out of termite swarf. :D

    Saw this on Mythbusters, I have also seen 55gal drums crush from a small pump. I still don't think a vacuum will pull a worm out of a piece of wood unless the hole has an open end.
