Wood Destroying Organism (WDO) Home Inspection Practice Exam

What indicates the possible presence of termites in a structure?

1. Regular inspections

2. Painted surfaces

3. Presence of galleries

4. Unusual odors

The correct answer is: Presence of galleries

The presence of galleries is a significant indicator of potential termite activity within a structure. Termites create these galleries as they feed on wood and other cellulose materials. These tunnels and channels are usually found within wood and can compromise the structural integrity of the affected materials. In particular, drywood termites are known for causing distinctive galleries that are often hidden within the wood, making their detection crucial during inspections. This aligns well with the known behaviors of termites, as they not only consume wood but also leave behind physical evidence in the form of these characteristic galleries. Finding such galleries during an inspection would warrant further investigation to confirm termite presence and assess damage. Other options, such as regular inspections, painted surfaces, and unusual odors, do not provide the same direct and clear evidence of termite infestation. While regular inspections certainly help in identifying pest issues before they escalate, they do not themselves indicate the presence of termites. Painted surfaces may hide signs of infestation rather than indicate it, and although unusual odors can occur in a severe infestation, they are not as definitive as finding galleries when diagnosing potential termite damage.
