About Blue Stain Pine (Beetle Kill Pine)

Beetle Kill Pine is the result of blue stain fungus that spreads from bark beetles to Lodgepole Pine, Douglas Fir, and Whitebark Pine trees. The blue stain pine fungus works symbiotically with the beetles by turning the tree wood into nutrients. Healthy trees would usually expel the beetles by producing resin, but cycles of warm weather have weakened many trees and prevented them from producing enough of their defensive resin.

A byproduct of the damage done by this hungry duo is a strong and beautiful piece of blue pine lumber that is streaked with a natural blue-grey stain. The beetles do not weaken or contaminate the wood, and the fungi is actually burnt away during the kiln drying process. Affordable, eco-friendly blue stain pine is all that is left behind.

We supply beetle kill pine lumber and have it milled for flooring, siding and timbers.  It comes with or without bore holes to provide you a clean or rustic look.

Give us a call and we can help you with any questions you have about using blue stain pine for furniture, ceilings, siding and more!

Why is Beetle Kill Pine lumber eco-friendly?

There is ongoing debate about the best way to prevent bark beetle damage, but one thing is certain: it’s better to recycle the wood than to burn it and release more CO2. Millions of acres of dead trees must be cleared to prevent forest fires, and that is why there is a big push to make blue stain pine the wood of choice for new housing projects. By choosing beetle kill pine, you simultaneously get beautiful wood and help recycle some of the trees that will otherwise be burned.

Where does Blue Stain Pine come from?

A lot beetle kill pine comes from outside of Colorado because our state doesn’t have many sawmills, due to its rugged landscape and inaccessibility. We try our best to source as much from the state as we can. Sometimes, though, the lumber does travel, but you can still save CO2 by using beetle kill pine because tons of it will be burned if not otherwise used.

Will a swan board continue to turn blue once it's installed in my house?

The blue stain will not continue to grow because we kiln dry our blue stain to eliminate the fungi and leave structurally sound pine with beautiful coloring.
