In regard to boring insect neutralization process temperature distributions in moist building materials being heated with the help of microwave apparatus are investigated and discussed. The objects of investigation were as follows: gypsum plaster, wood, red brick and also their compositions: gypsum – wood, gypsum plaster – red brick. Under the results of experimental research work therere proposed the time regimes to microwave heating process as applied to domestic mushroom, and Anobiidae beetle neutralization.
