# Austin termite guide: swarmers, shelter tubes, and risk conditions

Recognize common signs of subterranean termites and understand why an inspection must separate active evidence from old damage.

Published by Bugged Pest Control Sources: public agencies and university extension Updated 2026-08-13

The short answer

Subterranean termites travel between soil and wood through hidden routes or shelter tubes. Swarmers and equal-length shed wings are often the first visible clue, but inspection is needed to confirm activity.

Identification

## Start with observable evidence

-
  01

  Termite swarmers have a broad waist, straight antennae, and four wings of roughly equal length.

-
  02

  Shelter tubes look like narrow mud lines and may appear on foundations, piers, or plumbing penetrations.

-
  03

  Damaged wood may contain layered galleries with soil, but age and activity cannot be confirmed from appearance alone.

Where it lives

## Habitat around the home

Subterranean colonies are associated with soil and moisture. Wood-to-soil contact, leaks, poor drainage, concealed foundation paths, and stored cellulose can increase risk around a structure.

When it appears

## Central Texas seasonality

Swarming is commonly associated with warm conditions and moisture, often after rain. The hidden colony can remain active outside the brief swarming period.

Prevention

## Make the property less useful to termites

- Maintain drainage away from the foundation and repair leaks

- Avoid direct wood-to-soil contact where the building design allows

- Keep inspection lines visible rather than covering foundations with stored material

- Schedule an inspection when swarmers, tubes, or suspicious damage appear

Safety note

Do not open structural finishes or probe load-bearing wood unless it can be done safely. A pest inspection is not a structural engineering assessment.

When to ask for help

## The evidence has moved beyond a casual sighting

- Swarmers or equal-length shed wings are found indoors

- Shelter tubes, damaged wood, or moisture conditions appear at the structure

The DIY limit

Spot-treating visible wood or breaking tubes may not reach the colony or hidden routes. Effective options depend on construction, soil access, label directions, and a complete inspection.
