｜Flying Termites in Taiwan: What Are They and How to Prevent Infestation?
Introduction
During Taiwan’s humid spring and early summer, swarms of flying ants often appear around lights at night. However, these aren’t ordinary ants—they're termite alates, commonly referred to as “giant flying ants” or “big water ants” (大水蟻 in Chinese). Their presence could indicate a much larger termite colony nearby.
What Are "Big Water Ants"?
"Big water ants" are the reproductive caste of subterranean termites. These winged termites emerge en masse during mating season to form new colonies. Key characteristics include:
-
Four equally-sized wings
-
Dark brown/black segmented body
-
Weak flyers, often found near light sources
-
Shed wings easily, often leaving piles indoors
Why Do Flying Termites Appear?
-
High humidity and warm temperatures trigger their emergence.
-
Artificial lights attract them during nuptial flights.
-
Nearby termite colonies release alates to establish new nests.
-
Poor sealing of windows/doors allows entry into homes.
Are They Harmful?
Yes. While the alates themselves won’t bite, they represent an active termite population. Once they settle, they can form new colonies and begin feeding on wood, insulation, and structural components—causing significant property damage.
How to Prevent and Control Flying Termites
-
Turn off unnecessary outdoor/indoor lights during humid nights
-
Seal all windows, doors, and wall gaps
-
Install fine-mesh screens
-
Use light traps or bug zappers
-
Keep your home dry and fix leaks
-
Call a licensed pest control company for thorough inspection
Expert Insight
According to pest control specialists:
"Seeing flying termites at home is often just the tip of the iceberg. Without professional intervention, there's a high risk of hidden infestations already damaging your property."
Conclusion
If you notice flying termites, act fast. Proactive prevention and professional help are the best ways to avoid structural damage and expensive repairs.
