🔗 Save $6,000 A Year with My Complete Amish Home-Saving Method I teach: https://eliasyoder.com There is a little pile of sawdust on your windowsill. You swept it up last week and it is back. A small cone of it, no bigger than a thumbnail, and you cannot work out what is making it because there is nothing above it but painted wood.

That dust is the most useful message your house will ever send you, and almost nobody reads it. Two different creatures leave a pile like that. Their dust looks the same to a glance and they mean opposite things.

One is telling you water has been getting into your house for years. The other is telling you the wood came in with the trouble already inside it. Same pile, two different problems, and the treatment for one does nothing for the other.

My grandfather settled it for me with two pinches of dust and one question. I was fourteen and I had found sawdust under a barn beam and came running to say the barn was being eaten. He bent down, rubbed a pinch of it between finger and thumb, then walked me up to the house to a chestnut chair with a little pile under it and a few round holes in the leg, and rubbed a pinch of that.

The barn dust was coarse, like pencil shavings, with bits in it that were not wood. The chair dust was fine as flour. Then he asked me which of the two was made by a wet barn.

What we go through: Why carpenter ants do not eat wood at all, and what that tells you about your house Where to look for the leak once you know they are there How to tell a carpenter ant from the little ones on your counter Why powder post beetle holes are the exit and not the damage How those beetles got into your house in the first place, which is not through a window Why termites leave no sawdust at all, and what they leave instead The free paper and pencil test that tells you whether it is live or thirty years old Why spraying a carpenter ant colony can leave you with two nests instead of one Why drying a space out will finish a beetle infestation on its own Why a finish on bare wood is a fence, and why they are always in the unsanded underside What to carry a torch into before you buy a house The plain limit: I am not a pest man and I do not carry a licence.

What I can tell you is what the dust means and where to look. What I cannot tell you is whether a beam is still safe to stand under. If the wood is structural, a joist, a sill plate, a post carrying a roof, get somebody who can tell you what is left of it.

There is no scheme in any of this. There is a real trade in treating wood-boring insects, done by people who know more about it than I do. It is only that nobody makes a living telling you to rub a pinch of sawdust between your fingers and then go looking for a leak.

Tonight, find every place you have been sweeping up a little dust without thinking. Rub a pinch between finger and thumb. Coarse like pencil shavings, you have a leak to find.

Fine as flour, you have a piece of wood with a history. Then sweep it away, lay a sheet of white paper down, and write tonight's date on it. Tell me in the comments which kind of dust you found when you rubbed it, coarse or fine.

And if you have told me your county before, tell me this instead: what is the oldest piece of wood in your house, and do you know where it came from? Next time we go under the house, because the wood that rots first is never the wood you are looking at. I gathered the whole of it into a book at eliasyoder dot com.

The people who built this country with their hands knew that, and we are only just starting to remember it. #EliasYoder #CarpenterAnts #PowderPostBeetles #PestControl #HomeRepair #OldHouse #WoodRot #Termites #Homesteading #OldWays #SelfReliance #DIY #HouseInspection #Woodworking #HouseholdTips
