Visitor identification required

Anyone know what these are, found them in the sapwood of a couple of Oak boards.

I treat the timber with a borax solution twice a year which is supposed to kill unwanted visitors but these seemed to slip pass.

Wood wasp larvae?

Can't really see too clearly from the pic, but they look a lot like a longhorn beetle grub to me. Was the bark left on the boards?

 

I get a the little buggers in my yard in the chestnut or oak. Tends to only be in stuff with the bark left on though. I assume the beetle lays the eggs in the bark and the larvae then burrow further in. Usually only effects the sapwood.

 

My yard's on a organic farm so I can't be using any nasties, – just have to live with it. Not sure what's best to prevent it apart from as I said, remove the bark asap.

Longhorn beetles eat heartwood too.

If you find a larvae, kill it!

They have devastated oak woodlands in northern France.

I fed them to my chickens

When I'd find them(a lot)

Yeah the bark was left on.

I only found out when a customer contacted me to say he'd found them, so I checked other boards in the yard today and sure enough quite a few have holes in the bark.

Looks like I've got a few days of unstacking the boards and removing the bark ahead of me.

If they are only in the sap wood, might not be longhorn larvae.

Removing bark is always helpful though.

Pesky little wood eaters!
