The purpose for having a pest inspection is to determine if there are any signs of wood destroying insects (WDI) present on a property. Whether government-required or for your own personal protection, these inspections are a worthwhile investment.
If signs or suspicions are found during a home inspection, we always recommend that you have a pest inspection performed. A licensed pest inspector is able to determine if the presence is active. At times, these insects will visit for awhile, and then move on. Other times, they set up house and nest in different areas throughout the structure.
In either event, they can wreak havoc on the wood components of a house, at times weakening structures and causing damage to areas that may not be visible to the average homeowner.
It just makes good sense to have this information available prior to settlement, at which point, the problems, if they exist, become yours.
