I have a log home made from Poplar. Lately I have been getting a lot of small holes (pinhead size or smaller) with a sawdust pile left underneath it. Any idea as to what bug causes this? Also, how can I prevent it?
Sounds like Powder Post Beetle (Lyctoxylon dentatum) and can only be treated by stripping the logs to bare wood and treating with a borate like Shell Guard. Call Dave at 800-564-2987 to buy borate or Mike at 866-670-3020 for help having it professionally done.
