It's weird I've had those roaches come out form under the bark of trees I just dropped and started bucking. They have these real cool tunnels eaten into the tree, usually at points of earlier damage to the tree. I've about a cord of red oak I split and stacked in single rows on pallets about 2 years ago and this past September I noticed the bark comming off some of the top splits as it often does with oak and when I pealed the loose bark from the splits, the little buggers went scurrying every place. Only once have I actually found them in wood I've brought in to burn. They did not get active until the split got hot, then it was too late for them. Like Cheach and Chong, Up In Smoke! Just don't want to chance it.
