I recently obtained about 30bf of old maple that was stored in my grandfathers barn for ~40 years. It has wormholes (which I actually like) however they appear to still be active. I know it has been mentioned here before on how to heat them in a kiln, etc., to kill, but I want to try and take care of this in my garage/driveway. I thought of the following idea and wanted to run it past the community before trying it. In a nut-shell, creating a sealed plastic dome out of heavy duty plastic and setting off a couple of “bug-bomb” foggers. I would tape the ends of the plastic shut. In theory I would think this would kill the critters inside of the wood (4/4 at the thickest). I also wouldn’t think this would harm the wood as I still need to plane it but I sure don’t want to harm the wood or give it a permanent insecticide smell.

Thoughts? Have any of you done something similar?

wrap it in a black plastic so there is no air gaps and let it sit in the son for a few days depending where you are. A regular bug bomb wont kill powder post beetles or similar beetles, definitely not termites. zi see you are in Texas leave it sealed 3 -4 days they will suffocate

My concern would be that some of the insectide would up in and on the wood and once you started planing / sawing / sanding that you would be breathing the insecticide tainted sawdust.

If is small enough I microwave it, but those boards are too big. When I get wood with holes like that, I usually cut out the stuff with those little holes and burn it. For big worm holes where there are a limited number, I shoot the hole with carb cleaner- not real scientific but it is hell on bugs.
The thing is if you heat in the sun, how will you know you’ve killed them? Maybe you could submerge the wood? I know they thrive in dry wood but maybe they drown in water??

1+ heat in sun under black plastic. Keep track of the temp and the time. A few days at 140-150 degrees should kill most bugs.

How long are the boards? A home deep freezer runs about -20. Two days in, two out, repeat 5X. While bugs can endure a winter which comes on slowly enough, none of them can cope with sudden deep cold, over and over again.

Thanks for all the replies so far – good suggestions. The boards are all 48” long (I had to cut them that length to get them home from 1350 miles away). :-)

The problem with wormholes is you never know where the other end is going to come out.
Well, that and the fact they might not be stable.

Ditto the black plastic, that should kill them quite easily in TX, especially this time of year.

After they’re dead I personally seal the holes with CA glue, larger holes you can sprinkle a little baking soda in beforehand to catalyze the reaction and keep it from running all the way through.

update – I taped together two large construction trash bags and put out in the driveway. I will bake the maple for 4 days in this TX heat and check the results. David thanks for the tip about the CA glue.
