A cheap and effective way of setting up termite detection stations around domestic building (and other) structures...
Lived in Tucson Arizona in 1955 and neighbor had a fight with his wife. She slammed out of the house, cement block, slammed the door hard, and it fell in and fell to the floor. Termites had eaten out the whole framework holding the door. That was their first indication that the house was riddled with termites. While we may not like the termite, they as well as fungi, occupy very important niches in the ecology of our world. Video is a little preachy, but good introduction. Had to pick this one out as it shows all of chell's neighbors in full color. Study: Termites may have a larger role in future ecosystems
I was amazed, when I was in Guam, and saw one of the few remaining wooden power poles, after a grass fire had burned away one side of it. Damn thing was HOLLOW, inside! Even though that pole, like every wooden one, had been impregnated with creosote (which is injected into the wood in a method similar to how lumber is pressure treated), the termites had eaten their way through the creosote-impregnated wood (probably spitting it out behind them), until they got to the good wood in the center (because the creosote only goes in a couple inches). They had then eaten the center out of that pole, and gone on to find more food elsewhere. The damn thing was as hollow as a drinking straw, inside!
