Eradication of beetles attacking wooden historical buildings by humidity-controlled warm-air treatment
2023 - IRG/WP 23-11028
Humidity-controlled warm-air treatment is a method that kills mainly beetles that are damaging the wood. In this process, a heat-insulating and airtight covering is placed around the object building, and the temperature inside the covering is gradually raised to about 60°C, held for a certain period of time, and then gradually lowered. While maintained at 60°C, all forms of damaging insects - ad...

Physical barriers and bait toxicants: The Romeo and Juliet of future termite control
1991 - IRG/WP 1503
Soil chemical barriers are considered by some to be the most important technique for protecting buildings against subterranean termites in Australia (and elsewhere), providing a barrier against termite penetration. However, there is no such thing as a barrier that is 100 per cent +protective. And given the worldwide problems of using organochlorine termiticides, public awareness of chemical pollut...
