What Are Formosan Termites?
Unlike drywood termites, Formosan termites require soil contact and moisture. They build protective mud shelter tubes that allow them to travel above ground while remaining hidden.
Key Characteristics:
- Large underground colonies (often hundreds of thousands)
- Mud shelter tubes along foundations
- Swarm activity in late spring evenings
- Rapid wood consumption
- Preference for moist structural wood

How Formosan Termite Infestations Begin
Formosan Termite Treatment in Louisiana requires understanding colony establishment. Colonies typically begin when winged swarmers leave a mature nest and establish a new colony in moist soil.
Common yard risk factors:
- Poor drainage near foundations
- Leaking irrigation systems
- Wood-to-soil contact
- Mulch buildup against siding
- Tree stumps near the structure
After mating, swarmer’s shed their wings and seek protected soil contact. Within a few years, colonies expand dramatically.
Are Formosan Termites Common?
Yes. Formosan Termite Treatment in Louisiana is one of the most requested structural services due to regional climate conditions.
Contributing factors:
- High annual humidity
- Frequent rainstorms
- Slab construction
- Limited crawl space ventilation
- Flood-prone soil

Treatment Options for Formosan Termite Control
Formosan Termite Treatment in Louisiana focuses on creating a continuous protective barrier between soil and structure.
Professional service may include:
- Soil trenching around foundations
- Slab drilling and injection
- Termidor liquid barrier application
- Structural inspection and monitoring
- Moisture correction recommendations
- Wood-to-soil contact corrections
Termidor® termiticide treatment works through a non-repellent transfer effect. Termites cannot detect it, allowing workers to contact treated soil and carry the product back into the colony. This transfer effect disrupts the colony’s ability to sustain itself.

Often Asked Questions about Formosan Termites
What are Formosan termites?
They are aggressive subterranean termites capable of forming massive colonies. They cause rapid structural damage if untreated.
Are Formosan termites worse than regular termites?
Yes, colonies are larger and feed faster. Damage can progress quickly.
What time of year do they swarm in Louisiana?
Late spring evenings after rain are common swarm periods. Swarms may occur indoors or outdoors.
Do I need yearly termite treatment?
Inspections yearly are strongly advised. Retreatment depends on barrier integrity.
Can I treat termites myself?
DIY surface sprays are ineffective. Soil barrier creation requires professional equipment.
What attracts Formosan termites?
Moisture and wood-to-soil contact are primary attractants. Structural vulnerabilities increase risk.
How much damage can they cause?
Significant structural compromise can occur within a few years. Repair costs can exceed treatment cost.
Does insurance cover termite damage?
Most policies exclude termite damage. Prevention is critical.
Are termites active in winter?
They remain active underground year-round in Louisiana. Cold snaps slow but do not eliminate activity.
