Pest Identification: Old House Borers

Old house borers, scientifically known as Hylotrupes bajulus, are beetles that commonly infest wooden structures, causing damage. Old House Borers are part of the Powder Post Beetles. Key characteristics include their long, narrow appearance (5/8 to 1 inch) with black or brown color and long antennae. Larvae, the wood-damaging stage, are creamy white and legless, growing up to 1 inch. 

They primarily infest softwoods, especially pine, found in roofing, flooring, and framing. Larvae bore through wood, creating tunnels, weakening structural timbers, and causing significant damage. Signs of infestation include powder-like sawdust and audible feeding sounds in quiet conditions. 

The life cycle is long, with larvae residing in wood for years before becoming adults. Infestations demand prompt identification and treatment. Old house borers are found worldwide but more common in temperate regions. 

Control involves identifying and removing infested wood, using insecticides if needed, and preventive measures like using treated wood and maintaining low humidity. Distinguishing them from other wood-destroying insects is crucial, requiring consultation with pest management professionals for accurate identification and appropriate treatment.
