Scientists in Australia have discovered that a plant extract from the false sandalwood tree both repels and kills termites.
Here in California, houses periodically must be termited, that is, covered with a tent, and filled with poison. Our house is in need of this service. It is not cheap, and residents must vacate the premises for a couple of nights during tenting. Hapless, would-be burglars that decide to break in during a tenting die.
Imagine how much money would be saved if this extract could be injected into wood, as the article points out.
