Dry rot develops best at 75°F. and is said to be killed by a temperature of 110°F.41 Fully 70 per cent humidity is necessary in the air in which a timber is surrounded for the growth of this fungus, and probably the wood must be quite near its fibre saturation condition. Nevertheless Merulius lacrymans (one of the most important species) has been found to live four years and eight months in a dry condition.42 Thorough kiln-drying will kill this fungus, but will not prevent its redevelopment. Antiseptic treatment, such as creosoting, is the best prevention.
