A termite inspection isn’t just about identifying termites and other wood-destroying organisms—it’s also about clear communication between the inspector and the termite technicians who will complete the treatment.

Inspectors use two key tools to relay information: graphs and chalk marks.

Graphs: Mapping the Infestation

Graphs, created on paper or a tablet, provide an outline of the structure being inspected. While the version included in the official termite report isn’t drawn to scale, it should still closely resemble the home’s layout. This helps technicians quickly locate areas of infestation when performing treatment.

A well-drawn graph should also include helpful details such as:

• Locations of garage doors, attic, and crawlspace entrances
• Notable landmarks to assist with orientation

Most importantly, the inspector must clearly label the specific wood members where termites are found. Instead of broadly marking an area as “eaves,” they should specify which part of the structure is affected—whether it’s fascia, starter board, rafter tails, outriggers, or other structural components. This level of detail is crucial for:

• Guiding technicians to the exact treatment locations
• Helping future inspectors determine whether activity is new or old
• Providing clear information to wood workers handling termite damage repairs

Chalk Marks: On-Site Guidance

Every infestation noted on the graph should also be marked on the home itself with chalk. For example:

• If there are three areas of infestation in the garage, all three should be labeled.
• If the issue is on the second story, an arrow pointing up should be drawn below it.
• In hard-to-reach attic areas, a series of arrows should lead technicians to the problem spot.

Without these chalk markings, the treatment process can be compromised—technicians may waste time searching for termite activity, and worse, they might feel the inspector cut corners, leading them to do the same.

Why This Matters to Homeowners

Sloppy graphs and missing chalk marks can create a domino effect of poor service, ultimately leading to customer dissatisfaction. Homeowners should be concerned if they receive a termite report with a graph that doesn’t resemble their home or if they see a technician wandering around, unsure of where to treat.

Clear communication ensures thorough, effective treatment—and that’s what every homeowner deserves.
