The answer to 'inspection damage' is that common causes include pests burrowing, chewing, or nesting in insulation, drywall, or other building materials. Symptoms may include visible damage, holes, stains, or foul odors. Solutions depend on the type and extent of the damage, but often involve pest control treatment, repair or replacement of damaged materials, and sealing entry points.
If the damage is limited and you feel comfortable addressing it yourself, some DIY options include using caulk or sealant to fill small holes, replacing damaged insulation, or setting traps for pests. However, for more significant or complex issues, it's best to call a professional pest control technician. They can properly identify the pest, treat the infestation, and make any necessary structural repairs to prevent further damage.
