would termites dislike the smell or like the sawdustiness of it?
Well, coffee grounds definitely do not repel termites...
Just today, I discovered some in a pile of coffee grounds by some old deadwood. They were hiding under some used coffee filters that were helping to block out sunlight.
So, I'm no expert, but I think Philip Hyndman has some sound advice. It's definitely a risk that goes with the territory to consider...
If you're going to have any Hugelkultur beds in your yard, I would stick to the smaller sticks. And huge logs could maybe be chopped up or kept as far away as possible from your house. Keeping them aboveground and uncovered would probably also make them easier to inspect and monitor.
BTW, termites swarm
looking to establish new colonies once a year - so they can obviously easily cover some distance when flying. Thus, simply keeping wood a few feet away from your house is not much more than making a speed bump for them.
Of course, ecologically in a forest, termites are great for composting deadwood! The real problem is just that we humans happen to build our houses out of deadwood!
