Formosan Termite Inspection in Southaven, MS

What the Extension publication actually says about the north

MSU Extension reports isolated Formosan collections in DeSoto County. It does not say the species is widespread there, and this page does not say so either.

The 2026 Extension feature reports that the species is established in parts of 26 mostly southern and central Mississippi counties. In its description of the north, it refers to isolated collections in DeSoto County and says it is unclear whether those colonies persist. That is a careful statement, and it is the one this site repeats. A caller should not read it as proof of heavy local pressure, and should not read it as proof that there is none.

The distinction matters for the inspection. A building that is inspected because a neighbor saw swarmers should be checked as thoroughly as one that has a known colony, but the findings are reported as findings. An inspection that finds nothing is a useful result, and so is one that finds a small established colony.

How an inspection separates Formosan from other termites

The Extension describes Formosan swarmers as about half an inch long, with wings, and yellow to golden brown, and says native swarmers are darker and smaller. The inspection uses the swarmer as one piece of evidence and the colony structure as another.

A swarmer found on a windowsill tells the technician that a colony has reached a stage where it is sending out reproductives. It does not, on its own, say where the colony is. That is why the inspection goes to the foundation and to the wood, not to the window where the wings were found.

• Collect any swarmers or wings and keep them dry in an envelope, not a bag, so the technician can examine them
• Note the color and size, and whether the wings are all the same length, which is typical of a swarmer that has just left a colony
• Check the tubes, the galleries in the wood and the frass pattern, which differ between species
• Record the number of days since the last swarm and whether it followed rain, which the Extension links to swarming
• Confirm the identification with a specimen where it is needed for the treatment decision

What a Formosan finding means for the building

A confirmed finding changes the plan. The treatment options depend on where the colony is, how it entered and whether the building's wood and moisture can be changed to make it less attractive.

A finding is explained with three things: the location, the extent and the likely route. A colony in the sill beside a downspout has a different route from one that came up through a pier in a crawl space. The technician should say which of those the inspection supports and which it cannot yet confirm.

Damage is reported separately. Hollow wood, soft sills and blistered paint are recorded with photographs so the household knows what is structural and what is cosmetic. Repairs to damaged wood are a separate trade, and the report says so rather than folding them into a termite quote.

Keeping the inspection record useful

The inspection report is the record a household or an insurer will ask for later, so it should be specific about locations, readings and photographs.

A useful report shows where each tube was found, the moisture reading at each point, and the photographs taken at the same spots. It should say what was not inspected, such as a sealed crawl space or a wall that could not be opened, because an unlisted area is the one most likely to be the problem later.

A household should keep the report with the photographs and the date. If a second inspection is made, the two reports can be compared directly, which is the only reliable way to see whether a colony is growing, shrinking or has been stopped.
