When do termites swarm in South Florida? Learn how swarms differ by species, how to tell termites from flying ants and what to do next.

Termite swarm season in South Florida is often spring and early summer, but timing varies by species and weather. Subterranean and Formosan termites commonly swarm in the evening, while drywood swarmers can appear at other times.

What a swarm means

A swarm is a group of winged reproductive termites leaving a mature colony to start new ones. Seeing swarmers indoors suggests a colony may be inside or very close to the structure; seeing them outdoors is less conclusive. Either way, it is a reason to schedule an inspection with our team for termite control in Fort Lauderdale.

Swarm timing by species

TypeTypical swarm pattern
SubterraneanOften spring, frequently after rain
FormosanOften evening swarms in late spring and summer, attracted to lights

Timing varies with weather and location. These are general patterns, not predictions.

Termite or flying ant?

  • Termites: straight antennae, thick waist, wings of equal length.
  • Flying ants: bent antennae, narrow waist, front wings longer than the back.

Our guide to signs of termites lists other clues.

What to do after a swarm

  1. Collect a few insects or wings in a bag or tape them to a card.
  2. Turn off lights near doors and windows to reduce attraction.
  3. Vacuum swarmers inside, then discard the bag outside.
  4. Call for an inspection; do not rely on spraying swarmers.

Why invasive termites matter

University of Florida researchers have reported that Formosan and Asian subterranean termites are spreading farther across Florida than earlier predicted. See the sources below. For homeowners, the practical takeaway is routine inspection, especially if you have never had one. Our local pest control company in Fort Lauderdale team can inspect the property.
