Are “Flying Ants” Actually Termites? │ What to Do When They Invade Your Home │ Complete Guide │ Practical Solutions

1. The term “flying ants” (Taiwanese : 大水蟻) is a collective nickname for both termite and ant alates, with termite alates making up the vast majority.
2. Their nuptial flights occur at dusk—before or after rainfall—under high humidity and low air pressure, typically from 18:00 to 19:30.
3. Quick ID tip: a “sausage‑like” straight body signals a termite; a wasp‑waisted silhouette indicates an ant.: like a sausage = termite, figure with waist = ant

What Are “Flying Ants”?

In the summer nights, when you turn on the lights, a lot of little bugs fly in.Flying around the lights.Then they fall to the ground and crawl around, and some of them even bump into you, and everyone yells at them."big water ants", "big water ants"The

The name "Big Water Ants".It's a general term.(math.) genusContains termite and ant breeding ants.Inside, there are termite kings and queens, and ant males and queens.

Inside the big water ants, there are probably 95 %, all termites.The reason is that termites are more likely to live near humans. The reason is that termites are more likely to live near humans and fly in larger groups.

• “Flying ants” = reproductive castes of termites and ants
• Proportion of 95 % termites, 5 % ants
• Name derives from their tendency to appear around heavy rainfall

When Do They Appear?

The big water ants are concentrated inHigh humidity, high temperature in the eveningTaking off because of this weather will help them to fly with less effort and find new nests better.

in particularBefore and after the rainThe humidity of the air is very high and evenpouringHowever, there is a higher chance for the emergence of big water ants.It doesn't appear to be a big water ant which means it's going to rain.The

The big water ants in Taiwan are concentrated from April to June in theTake off at 6:30pm and continue until 7:30pm.When it is 8 o'clock in the evening, almost all of them are in hiding.

• April–June
• 18:30 – 19:30
• Warm, humid air—often before or after rain

Why Do They Fly?

This isMating Rituals of TermitesThe termites will fly to a light source to gather and land, which is known as splitting flight.

After landing, the termites will start to look for their mates. The king will follow the pheromone odor and chase the queen, and they will line up two by two until they find a new home.It's called tailgating.The

After finding a new home, termites will start mating and laying eggs to build up a colony.But the success rate is very lowEven if the termites hatch successfully, their production rate is still very slow. Usually, termites can only produce 10 to 20 worker ants in their first year of life.
　

• Swarming enables mating and colony founding
• Strong positive phototaxis (light attraction)
• Colony establishment rate < 1 % for termites

Are They Harmful? What If They Enter My Home?

No harm done to water antsIt won't matter if it flies into your house. It doesn't carry germs.And they don't bite humans.The

Termites feed on wood and commonly invade human homes to eat wood furniture. There are at least tens to hundreds of thousands of termites that can chew up furniture.It took more than 10 years to get there.The

The chance of termites flying into your home and surviving for a year is less than 1.%, and the chance of termites growing for 10 years is even slimmer.Just remove it without worrying too much.The

Termite vs. Ant: Three‑Second Visual ID

ey Trait	Termite	Ant
Antennae	One joint, one bead, straight line	Bent elbow, pronounced segmentation
Waist	No waist, thick.	With a visible waistline
Wings	Fore and hind wings of the same length and equal color	Longer forewings, shorter hindwings

Look at the contact horns, look at the waist, look at the wings, and you'll break down the identity in three seconds.

　

• Focus 1: Bead‑like straight antennae → termite
• Point 2: Narrow “wasp waist” → ant
• Point 3: Equal‑length wings are the tell‑tale sign of termites

How to Handle Indoor Swarms

1. Turn off bright lights or switch to warm bulbs; less UV/blue light means fewer insects.
2. Use a basin of water beneath a lamp on the balcony—the reflection lures alates to drown.
3. Physically block entry: close windows, install screens, seal gaps.
4. Use insecticides sparingly; call professionals if structural termite damage is suspected.

• Preferred light source change, fundamental reduction
• Water basin trapping is economical and environmentally friendly
• Professional Inspection for Termite Concerns

Ecological Roles and Benefits

• Termites : expert wood decomposers that recycle dead timber and aerate soil through tunneling.
• Ants : seed dispersers and natural pest controllers; some species form mutualisms with plants.
• They are ecological heroes that become “pests” only when they overlap with human habitats.
• Ants hunt pests and transport seeds
• Human-Pest Conflict Stems from Habitat Overlap

FAQ

1. The name refers to their mass swarming around lights during the rainy season, especially before and after heavy showers.
2. Termite mandibles are weak; they do not bite people.
3. Not necessarily; they may just be attracted to lights. Still, inspect woodwork to be safe.
4. Yes, but clean the zapper grid regularly to prevent clogging.
5. They do not feed while airborne. After landing, termites consume wood, whereas ants hunt or cultivate fungi.
6. High humidity prevents wing drying, low pressure aids flight, and predators are fewer right after rain.
7. Paired individuals may live for years; single ones usually die within days.
8. If you see a big water ant, does it mean it's going to rain?
   • Not necessarily. It just means high humidity.
