Under ideal conditions in many southern states, adults may appear after three to five years, sometimes remaining in larval tunnels for as long as 10 months before emergence. Adults emerge June, July and August with females attracted to dry, seasoned wood where eggs are laid reinfesting additional softwood. Log Houses Log houses have become quite popular in many states. Logs are partly or completely debarked before being cut into lengths and notched as part of a log house kit. These logs are strapped together and dipped into a preservative with the kit completed in a few days or weeks.
Logs remain outdoors at the manufacturing site until the kit is complete.
Then the entire house kit may be fumigated, loaded onto trucks and delivered to the construction site where logs may sit again before the homeowner assembles the house. If a log house kit produced during the fall is delivered to the building site, but assembly not made until spring or summer, any eggs laid in the cracks and crevices of the logs will hatch in only about nine days with the first stage larvae immediately penetrating the wood. Larvae may have gone below the depth of preservative treatment before being dipped. Adult emergence holes are discovered easily. Reinfestation of log houses seems greater than conventional houses because of more exposed wood and the shorter feeding time of larvae.
