How to treat for bugs?

I could tell much from the photo. Was there little places with dust where they have bored? If there was it sounds like powder post beetles. You can get a product called Boracare. This can be ordered from the internet or bought locally from exterminators. They just happen. I hear you need to really wet the wood with this product.
If it is powder poet beetles, my exterminator friend tells me you can carry them into your house if your make something and move it indoors with you…..
Treat it

You better check the rest of your stock. If you have more then get it out of your shop quickly.
If your shop is in your basement or garage you better keep an eye on your furniture. Powder Post Beetles can be very invasive in the right conditions.

The best way to prevent bug infestations is to keep the wood dry. Getting rid of an infestation is another matter and one that I’m not familiar with.

You guys are scaring me.

If my lumber is dry, I shouldn’t have any problem. Right?

If it is borer… and if you have an infestation…you need to do (what we call here in NZ) Borer bomb, there are many products that will kill most insects… but the best time to catch them is when they are on the wing (here in NZ it is during the summer) do one near the beginning and near the end of the season and then every year to keep them under control and you find they slowly disappear. We just did our last one about 2 weeks ago…

The reason getting them on the wing is because that is usually their mating season so slowly controlling them…

As for the house most insects the bore in to wood don’t like or touch treated wood… but for your lumber stock you need to keep an eye on it…

I’ve not seen any signs of bugs, so could this be damage from the past and now everything is ok? I’m not going to use that piece of wood, but I’m more worried about my other wood and the building it is stored near.

I’ve had the odd plank of American white oak pretty much the same as that. I asked my timber merchant about them. According to him, these are boreholes from prior to kiln drying, the critters that made them are long gone. Of course, he might just be trying to fob me off…
I once had live worm type things come out off some WBP ply, which did surprise me.

-- Do or do not, there is no try

What you need:
1 Ice Pick
1 Pack safety matches
1 gallon gasoline (87 octane is fine).

Application:
Pour gasoline all over the affected area.
Set the gasoline aflame with a match from the pack of safety matches.
As the critters run away from the fire, stab them with the ice pick.

Theat’s the only way to get rid of wood critters, or ummm, maybe it was crotch critters. (I never had either so I’ve forgotten which).

-- Improvise.... Adapt...... Overcome!

The first thing to do is determine whether or not they, or their larvae, are still in the wood. If you see small piles of wood dust laying around, they are there. I cannot tell by the pic, but if the holes you see are slanted then they were made before the wood was sliced; if they are flat and round, then they may be fresh. If the wood has been correctly kiln dried and heat treated, then you will be just fine; note that it needs to be heat treated! If it is just dried the larvae will be unaffected. The wood needs to be at about 135 degrees f. to kill them off. The best thing to do to keep them from infesting your area is to keep it clean; sweep up all sawdust as soon as possible and keep the wood wiped off. You can get a wood bug killer from most wood sales points, you can spray it on and it will penetrate the wood to kill the critters inside and keep them from causing more problems.

what I do is …. and only becourse I havn´t a freezer that can go down to – 40 degrees celcius below 0
but who has those they are exstreemly expencive … here in the winther when the wether is under
-10 degree celcius I put he wood outside for a cuople of days take them in 3-4 days
and then they return to the freezing wether for another cuople of days
all the time it has been in a thight closed sealed plasticbag
to kill the egg from the bettle woodworms you have to go under -40 degree celcius
or as I do making a fals spring the higher freezing temp can kill the worms and beetles
but it can´t kill the egg thats why you have to make a fals spring to transform the egg to woodworms
and pop the cocoons to flying insects

another way is to put the wood in an owen with over 55 degree celcius a couplle of hours
but the time depend on the the mass and how the owen behave but between 50 and 100 degree celcius
shuold be fine .........but its not all wood /furniture you can and want to do that with

theese two ways will kill the bugs and if you fill the holes with plasticwoodfiller or something simular
you only have to chec for new attachs by seeing if there is new holes

one backslass to this metodes is it doesn´t obstruct future attacks
but there is several chemicals out there that can help you with this and if you lack the wood after the treadment it shuold be relative safe to tuch the wood surface
using resin and other chemicals beased on oil can tread the wood if its flodded with it but they smell and wont
block for future attack either

if you leve in a zone where you don´t have low freezing temp. you can sneak to use the boss´s freezer
but don´t tell you are coming worms in it ….belive me … then better buy a combi freedge/freezer closet yourself …. that can be used in the shop for sodapops and beers
and ceep the 2 seconds glue fresh a little longer …... :-)

good luck on your beetle rampage

People get them at times. They are in the wood. Treat them, use the wood and move on.

yep i,ve hadm to, in a project i made

-- IF YOUR NOT MAKING DUST...YOU ARE COLLECTING IT! SOUTH CAROLINA.

I treat with Boracare to stop it before it starts in my air drying yard. It will supossidly will kill them also. Kiln drying will also kill anything in the wood now.
