TERMITE CONTROL INVESTIGATION INSPECTION OF SPECIMENS AFTER 100 MONTHS EXPOSURE
This is a report of progress in the 15-year investigation to determine the most effective preservative with minimum retention to be used in treating either oak, pine or fir species to reduce decay and termite attack. The results of the investigation after 100 months exposure of the specimens are: 1) Specimens treated with Coal Tar Creosote show less decay and termite attack than specimens treated with other preservatives. 2) Chromated Zinc Chloride and Tanalith are affording less protection against decay and termite attack than the other preservatives. 3) In general, the fir specimens treated with most of the preservatives, are subject to less decay and termite attack than the oak and pine specimens, however, oak is generally more resistant to decay and termite attack than pine or fir when not treated. 4) The decay and termite attack is quite rapid in the untreated specimens but this can be reduced considerably by treating the specimens with the lower retentions of any of the preservatives, even Chromated Zinc Chloride or Tanalith. From the data secured during the inspection of treated specimens of oak, fir and pine species after 100 months exposure, it seems logical to conclude that Coal Tar Creosote is affording more resistance to decay and termite attack than the other preservatives.
