Topic tags/keywords: cedar beetles bugs curing question

First Hello to everyone.
I am new to the site and looking forward to learning from everyone, sharing, discussing, and just enjoying the woodworking craft.
I found the forum while trying to find information about bugs invading my cedar planks.
I can’t really find any information… I found information about ambrosia beetles in walnut but nothing about cedar.

The cedar was cut earlier this year and has been air curing in an open air carport out of the weather. Everything has been fine until now. It appears I have holes in the sides of the planks (but only the sides that still have bark it appears), none on the top or bottom surfaces, and piles of sawdust on the next lower plank under the holes.

Please see the pics and tell me what you think they are and the best way to get rid of them.

The lumber will pretty much stay where it is until spring, so I don’t know if i need to spray it now, cut off how ever deep the critters are and then spray, or go hole by hole and inject something.
This is some beautiful cedar and I don’t want to lose it.
Any advise is appriciated.

It is most likely ambrosia beetles. They will leave as the lumber dries. They typically only infest the sapwood. They will not get in the heartwood. Putting a fan on the stack will accelerate the drying, and that will accelerate their leaving the wood.

Some type of borer is eating your sap wood Remove the bark so the sap side will dry faster, most of these types of bugs will only attack wet wood.

Thanks for the information.
Makes sense.

Here is what the top of one of the planks look like just to show you what they are eatin on.

This pic is one of the narrower planks. Some of the wider ones have some really awesome colors, patterns, and I think are gourgeous.
I had the mill do a straight pass through cut which left the bark on, and then I didn’t remove the bark either.
First tree I ever took a tree to the mill by myself, so rookie mistake.
All the other wood I have ever used; my step-dad already had milled.

This weekend I will take off the bark and aim a few fans at the stack to run the little dudes out.
Thanks for the tips.
