Hi there. First message.
I've just had the first early start of this season to the rocket stove, and collected some woodfuel from the stack outside the house. As usual, gathered 2-3 times the amount that fits in the feed chamber of the J-tube roket, so as to burn 1 lot, while drying the other two.
But, i've seen some sawdust in the woodfuel pile, and it turns that there's some woodworm (http://en.wikipedia.org/wiki/Woodworm) infestation in it.
So, when bringing the fuel in the house, also some undesired bugs come inside.
How do yo people manage this? The rrof is made of wood, treated though.
On the other hand, even the wood in the roof is treated and the bugs may not attack it, the woodfuel stack is being eaten and some of the fuel is turning to sawdust, so there's some room for concern here.
Woodworm is great for its ability to increase total surface area in the wood while opening up vents for greater oxygen penetration for more effective combustion. Also the woodworms themselves are highly combustible when fully dried in close proximity to a flame! But if you're concerned about the woodworm basic animal rights to peace without fiery death, you may need to lure them out with som maple syrup or something...
