The following test reports have been published CSIRO Australia 1958 - Susceptibility of Termites to boric acid and New Zealand Forest Service - Toxicities of some Waterborne wood preservatives to wood-destroying fungi.
It has been approved by the Institute of Building Technology in Berlin as effective against fungi and insects.

varnish, to prevent rain leaching out the salt.
For posts, beams and poles prepare a solution in a drum or trench and soak the timber for 24 hours. For proper protection use the following quantities:
- Timber thickness less than 40 mm = 300 ml solution p.sqm
- Timber thickness more than 40 mm = 350 ml solution p.sqm
For small holes from borers a 5% solution may be injected into the holes using a syringe
