Which of the following does NOT typically lead to reinfestation by the Old House Borer?

The factor that does not typically lead to reinfestation by the Old House Borer is the characteristic of being solitary insects. Old House Borers, scientifically known as Hylotrupes bajulus, are primarily wood-boring beetles that are known for infesting seasoned softwood. They generally live in and around already infested wood rather than being solitary; although they might not have large colonies or social structures like some insects, their behavior and life cycle can still lead to reinfestation through their life stages.

When reinfestation occurs, it is more closely associated with factors such as the availability of suitable food sources (like seasoned softwoods) and the conditions provided within old wooden structures. These environmental factors create a more conducive setting for the Old House Borer to thrive. Additionally, their presence in old housing often provides a relative abundance of infested wood.

In contrast, the presence of Old House Borers in new housing is less common because the wood used is typically not seasoned, which means it is less likely to be infested. Reinvasion or infestation is, therefore, more a function of environmental and material factors rather than the solitary nature of the insects themselves.
