A cluster of wings on a Monterey windowsill can come from termites or flying ants. Even confirmed termite swarmers do not show how much wood is affected. Save a few insects or clear photos. Note whether you watched them emerge from wood, merely found them indoors, or saw them enter through an opening. An inspection can then look for the source and assess what is visible.
First, keep the evidence
Photograph the insects, wings, and exact spot before cleaning. Put a few intact insects in a sealed container if practical. Note the date, weather, and whether the insects appeared from a wall, trim, floor, or an outside opening. Do not pry into wood or enter an unsafe attic or crawl space to investigate. The source location can matter more than the number of insects on the floor.
Termite or flying ant?
Look at an intact insect, since wings alone can be hard to judge.
- Termites have a broad waist and front and rear wings of similar length.
- Winged ants have a pinched waist, elbowed antennae, and shorter rear wings.
- If the sample is damaged, ask the inspector to identify it. Both groups can shed wings.
The season narrows the question, but does not settle it
UC guidance describes western drywood termite swarms mainly in summer and fall. Common subterranean termites may swarm on warm, clear days after soaking rain in spring or fall. Weather and species change the timing. If you watched insects emerge from a wood member, show that spot to the inspector. Insects found indoors may have entered from outside. Neither the room nor the season alone locates a colony or shows the extent of damage.
Other clues to record
Drywood termite pellets may collect beneath a small opening in wood. UC notes that pellets alone cannot establish whether a colony is active or how far it extends. Subterranean termites can leave shelter tubes along a foundation or other surfaces. Photograph these signs without scraping or covering them; a professional can assess them alongside the insect sample and accessible wood.
What to ask at the inspection
Ask which areas were accessible, which signs support the identification, and what could not be checked. A California structural pest report addresses visible, accessible conditions; concealed areas may need further inspection. If treatment is proposed, ask how the recommended method fits the identified termite and where its coverage stops. A drywood spot treatment, for example, depends on locating the affected wood and can miss hidden colonies. See our guide to drywood and subterranean termites for the different clues and methods.
A useful next step
If you find insects indoors, photograph them and note any observed emergence point. Request an inspection while the evidence is available. A swarm alone does not call for fumigation; ask the inspector to connect a written recommendation to the signs found.

Frequently Asked Questions
Do shed wings prove that termites are active inside my home?
No. Both ants and termites shed wings, and wings alone do not show the source, current activity, or extent. Keep a sample and have the location inspected.
When do termites swarm near Monterey?
Timing varies by species and weather. UC describes drywood swarms mainly in summer and fall and common subterranean swarms after spring or fall rain. An inspector should identify the insect rather than relying on the month.
Does every termite swarm require fumigation?
No. The species, evidence, access, and distribution of affected wood determine the options. Ask the inspector to explain why a localized or whole-structure approach fits the documented findings.
