What type of exit holes does the old house borer create?

The old house borer creates exit holes that typically measure between 1/4" to 3/8" in diameter. This specific size range is distinctive and helps in identifying the presence of the pest, as it differs from the exit holes created by other wood-boring insects. Understanding the size of the exit holes is crucial for pest control operators in diagnosing infestations and determining the appropriate measures to mitigate the problem. The old house borer, being a type of wood borer that affects older structures, leaves these relatively larger exit holes as it emerges from the wood, which is also a key sign of its activity and potential damage to the structure. Recognizing these characteristics aids in effective pest management and avoiding further deterioration of wooden materials.
