Timber is a sustainable building material that can be damaged by several biologicalagents, like insect activity, fungal decay and more. This is one of the most common problems inhistorical buildings. This paper gives an overview of microwave (MW) technologies, whichhave been used in wood boring insect control. Electromagnetic waves penetrate throughout theentire volume of treated material, causing water in wood and wood boring insects infestingwood to heat up simultaneously. The rise of temperature is the main effect used in MW pestcontrol. A microwave wood boring insect neutralisation device herein is introduced. This paperlooks at the long-distance microwave irradiation and radiation energy distribution of theirradiated surface. Tests for evaluation of wood pest elimination by MW radiation are specifiedand discussed.
