DEALING WITH BORER
EFFICIENCY OF KILN-DRYING Adult borers (beetles) appear from November to January in timber. The eggs are laid in the cracks and under uneven parts of the timber, and may readily be seen with the assistance of a strong hand lens or a microscope. The young larvae hatch from the eggs and bore straight into the timber. By splitting open thoroughly one piece a fortnight, it will be possible to obtain a complete life history. The heat generated during the ordinary dry kiln operation is sufficient to kill borers infesting woods. Experiments by Dr. P. C. Craighead have shown that the larvae of the redheaded ash borer (neoclytus erythrocephalus Fab.) can be killed in any kiln process which can be considered practical for the seasoning of ash, regardless of the thickness. Such treatment will also prevent further attack by the red-headed ash borer.
