When Termites Swarm in Orlando, and What the Swarm Tells You

Why do termites swarm in spring?

Because UF/IFAS describes winged termites appearing roughly March through June across the state. The timing is a statewide pattern, so a spring sighting is ordinary for Florida. The real question is what the sighting is connected to in your building.

Most sightings people report are a few wings on a windowsill, a small cloud of insects near a light, or shed wings on a floor. The first step is not to panic but to confirm what the insects are. Winged insects can be hard to tell apart by eye, so keep a sample rather than deciding from memory.

UF/IFAS states plainly that finding winged termites does not by itself prove an infestation. That is the sentence to keep in mind. A swarm tells you the season has arrived and that winged insects are present; it does not, by itself, say where they came from or whether the wood in your building is affected.

The sensible response is a short checklist. Keep a sample, note where you found the wings, photograph them, and ask for an inspection before anything is sprayed. The inspection, rather than the swarm, decides what is in the wood.

When is the swarm season in Orlando?

Across Florida, UF/IFAS puts winged termites in roughly March through June. Formosan subterranean termite swarms are placed around late April or early May by UF/IFAS-linked sources. The calendar below sets those months beside the wet season, which affects the rest of the year's pest work.

The calendar is a planning aid, not a promise. Swarms depend on the weather and on the colony, and a dry or wet spring can move the timing. Treat the months as the window in which a sighting is most likely, and keep watching outside them.

Rainfall matters for the rest of the year. The National Weather Service's annual climate report for Orlando International Airport lists a precipitation normal of about 51 inches a year for the 1991 to 2020 period. Moisture around a building is one of the things a technician checks during an inspection.

Use the calendar to decide when to ask for an inspection. Booking one in the spring is sensible, but an inspection in any month answers the question that matters, which is whether the wood is being damaged.

If a sighting falls outside the window, do not dismiss it. The months are a guide to when wings are most often reported, and a sighting in another month is still worth recording and mentioning to an inspector.

What does a termite inspection check?

A termite inspection looks for signs of activity in and around the structure and reports what it finds. It does not promise that nothing is present. In a Florida real-estate transaction, the report must be made by a qualified person and written on FDACS Form 13645.

Start with what the inspector covers, not only what they find. The inspection should cover the accessible parts of the structure and say what could not be reached. Crawlspaces, attics and areas behind finishes may be limited, and an honest report names those limits rather than hiding them.

Ask for the designation. A person who inspects for wood-destroying organisms in a real-estate sale should hold the WDO inspector designation on their state identification card. Check that the card is shown to you, and that the report is on the state form whenever a written report is required.

Licensees may not add disclaimers to that form. Any limit on the inspection therefore belongs in the scope and in the conversation, not in extra wording on the form, so read the form in full and ask about anything it does not say.

Ask the inspector to explain the findings in person, not only through the form. Listen for what the report says about the parts of the building that were not reached, and ask how those parts would be checked if access were possible. A clear answer shows that the limits were understood, and a vague one is worth pressing before the report is relied on.

Is a swarm the same thing as damage?

Not necessarily. A swarm is an event and damage is a condition of the wood. An inspection that looks for activity in the structure is what separates the two, and that is the step that decides whether a treatment is needed.

Homeowners often read a swarm as proof of damage, and that reading goes further than the UF/IFAS guidance does. The insects are evidence that a question is worth asking, and the answer comes from the building rather than from the swarm.

That is why identification is worth doing before any spending. UF/IFAS offers free sample identification, and its Termite Distribution Map shows which species are reported where in the state. A sample in a sealed container, with the date and the place where it was found, is the cheapest first step you can take.

A map cannot tell you what is inside a particular wall, so use it to frame the question, not to answer it. The answer for your building comes from an inspection and, where needed, from a sample identified for you.

What should I do after I see wings?

Keep one or two insects, photograph where you found them, look for wings near windows and doors, and ask for an inspection rather than a treatment. Do not treat the swarm as settling the question either way until the wood has been looked at.

Start with the practical steps. Put a sample in a small sealed container and write down the date and the room. Photograph the insects beside a coin or a ruler so the size is visible. Collect shed wings from the window ledge too, because they can be enough for a first identification.

Then look at the building from the outside first. Note wood in contact with soil, the lower edges of wooden frames, and any crack or gap where the outside meets the structure. Describe what you see to the technician rather than trying to decide alone what it means.

Do not spray or pour products into wall voids or over a swarm before an inspection. A treatment applied first can make the findings harder to read, so ask the inspector to look before anything is applied.

How does the swarm season fit a treatment plan?

A swarm is usually the moment a homeowner notices termites, not the start of the work. A treatment plan begins with the inspection, sets out the scope and timing, and is confirmed on site before any work begins.

Ask for the sequence in writing: inspection first, then a written finding, then a scope of work with the method named and the figure confirmed on site. A treatment offered on the phone before anyone has looked at the wood is a plan without a diagnosis behind it.

Timing can matter. Ask whether a follow-up visit is included in the scope, and when it would happen. A plan that leaves the follow-up unexplained is harder to check later, so ask for it to be written down.

A call to (855) 974-4733 is a sensible first step for a sighting, and the person who answers can explain the sequence before anyone visits. The scope itself is decided once the building has been seen, not from the description of the swarm.

What should I record over the rest of the year?

A dated record of sightings, moisture and repairs is the cheapest monitoring a homeowner can do. It shows whether a spring sighting was a one-off or part of a pattern, and it gives the inspector a timeline to work from on the visit.

Keep one page with the date of each sighting, the room or outside area, the number of insects or wings, and whether they were alive. Add a line for any repair, leak or change to the soil and drainage next to the foundation, because moisture is one of the things an inspector will ask about. The record costs nothing and can be handed over in a minute.

Repeat a walk through the building at about the same time each month during the spring. Look at the places a technician checks first: the lower edges of wood framing, the areas around doors and windows that touch the structure, and any crack where the outside meets the inside. The purpose is not to diagnose at home but to notice change and write it down.

Share the record with the inspector before the inspection rather than after. A timeline that says wings were found in April and again in May is far more useful than a description given from memory, and it helps the inspection decide where to look first and how far to look.
