The study focused on the effectiveness of using bio based preservatives as a controlling measure to biodetoriation from fungi and termite for wood in service. Wood samples of Triplochiton scleroxylon, Gmelina arborea, Ceiba pentandra used for the study were obtained from the sawmill of Ondo State Afforestation Project (OSAP) Oluwa and processed at the wood workshop of the Department of Forestry and Wood Technology, Federal University of Technology Akure. The sample were converted into 60 mm × 20 mm × 20 mm and seasoned to 12 % moisture content. The samples were treated with bio-preservatives from Parkia biglobosa, Tridax procumbens and tar oil obtained via pyrolysis. This study showed that even though Ceiba pentandra has the highest retention for the preservatives, it is the most susceptible to fungal and termite attack. Gmelina arborea with the lowest retention have resistance to termite and fungal attack, thus, the effectiveness of the preservatives on the wood samples is not only determined by the retention level of each preservative but also the chemical constituent (pH) of the preservative. This study recommends the use of tar oil for preservation of the wood samples against termite where colour is not important while, ethanolic extract of Tridax procumbens can be used to preserve wood against fungal attack.
