I've got a Finnish book, the name would translate like 'Doctoring Houses', and here it is considered to be the bible of traditional house building and renovation. The book has a chapter about rot fungi, and it also lists chemical treatments which have been used to combat fungi. The result; those chemicals either are so mild that they have no significant effect on the fungi, or they are so strong that they are also harmful for humans. So, even if there was a liquid killing the rot fungi, I don't know if I could ever feel safe sleeping in a room treated with such chemicals - if I'd happen to pass out because of being exposed to toxic chemicals, it might take weeks until someone pays a visit to check if I'm okay...

Today I've spent few hours scraping and vacuuming away almost all the visible parts of the fungi. I collected the dry pieces of fungi into a metal bucket, and finally emptied the bucket into a camp-fire on the yard. As I watched the fungi burn I thought that this reminds me of the movie Aliens; there is this creepy stuff growing on surfaces, you find yourself fighting against an enemy which is not just a collection of individuals but more like a hive. No matter how many of 'em you kill, if a single egg is left somewhere it might regrow the entire hive. So the best option seems to be to take off and nuke the entire site from orbit. It's the only way to be sure.

But, luckily enough, the 'Doctoring Houses' book gives a lot more optimistic look; "just make the conditions unfavourable for the fungi and it will stop growing. (Take care of proper ventilation, make sure that no wooden structures are constantly exposed to moisture, and such basic stuff). And, to kill it, blast it with a hot air blower." - Oh I know how to do that, so let's rock! =)
