Invasive hybrid termite species discovered in Florida
FORT LAUDERDALE, Fla. (WFLA) — A new study conducted by the University of Florida Institute of Food and Agricultural Sciences has confirmed the presence of hybrid termite colonies in South Florida. Published in the journal Proceedings of the Royal Society B, the study documents how two variations of the destructive and invasive species, the Formosan subterranean termites and Asian subterranean termites, are not only coexisting but are now crossbreeding. According to the findings, both termite species are prone to forming massive colonies and, once mature, the winged termites can be sent out to find a mate and establish a new nest as king and queen. Suspicions about their ability to breed began about 10 years ago when Thomas Chouvenc, associate professor of urban entomology at the UF/IFAS Fort Lauderdale Research and Education Center, said that they observed males and females from both species exhibiting interspecies courtship behaviors. 'This was unexpected, and it raised red flags about the possibility of hybrid populations forming in the field,' said Chouvenc.

'At first, I could not believe it, as I was hoping to never find it,' said Chouvenc. 'Since then, we have confirmed the presence of hybrid swarms every year since 2021, including in April 2025.' Genetic testing confirmed the new species to be samples of hybrid termites, sharing half of their genes with each of the two species.

'This may be a Florida story now, but it likely won't stay just in Florida. Give it time,' Chauvenc warned. The hybridization process has likely been underway for a decade and is impossible to stop. However, scientists say that understanding the biology of this new termite species, and its weaknesses, could help improve pest management and foster better solutions as time goes on.

Preventing Termite Damage in South Louisiana Construction
'South Louisiana is home to several termite species, including subterranean termites, which are known for their ability to cause severe structural damage.' — Jules Albert III NEW ORLEANS, LA, UNITED STATES, January 30, 2025 / / -- Termite damage is a significant concern for property owners and builders in South Louisiana. The region's warm, humid climate provides ideal conditions for termite activity, making preventive measures essential in residential and commercial construction. Without proper precautions, termites can cause extensive structural damage, leading to costly repairs and safety concerns. Jules Albert III, owner of Jaymar Construction LLC in Slidell, Louisiana, emphasizes the importance of incorporating termite-resistant materials and construction techniques to protect buildings from infestations. Understanding the Termite Threat in South Louisiana 'South Louisiana is home to several termite species, including subterranean termites, which are known for their ability to cause severe structural damage. These termites build underground colonies and travel through soil to access wooden structures,' notes Albert III. Once inside, they consume cellulose-based materials, including wood framing, flooring, and drywall, weakening the integrity of a building over time. The region has also experienced increasing threats from Formosan termites, an aggressive species capable of forming large colonies and causing extensive damage in a short period. Without early detection and treatment, an infestation can compromise the structural stability of a home or commercial property. Key Construction Strategies to Prevent Termite Damage Preventing termite infestations starts at the construction phase. Builders and property owners can implement several strategies to minimize the risk of termite intrusion and structural damage. 1. Pre-Construction Soil Treatment One of the most effective ways to prevent subterranean termites is to treat the soil before construction begins. This involves applying a termiticide barrier around the foundation, creating a chemical shield that deters termites from tunneling into the structure. Pre-construction treatments must be performed by licensed pest control professionals following local regulations. This step is critical in South Louisiana, where termite activity is high throughout the year. 2. Use of Termite-Resistant Building Materials Selecting termite-resistant materials can significantly reduce the risk of infestation. Some of the best options include: Pressure-Treated Wood – Treated lumber is infused with chemicals that repel termites, making it a reliable choice for framing, decking, and structural supports. Concrete and Steel – Using non-cellulose materials in key structural components, such as foundations and support beams, eliminates food sources for termites. Composite Materials – Alternative building materials, such as fiber cement siding and synthetic trim, provide durability while reducing vulnerability to termites. Incorporating these materials during construction enhances the longevity and resilience of a building. 3. Proper Foundation Design and Sealing A well-constructed foundation acts as a critical defense against termites. Preventive measures include: Raised Foundations – Elevating the structure above ground level reduces direct contact with soil, making it harder for termites to reach wooden components. Concrete Slabs – Solid concrete foundations create a physical barrier, blocking termites from tunneling through the ground into a structure. Sealing Entry Points – Small cracks in the foundation, utility penetrations, and expansion joints should be sealed with caulk or foam to prevent termite access. By ensuring a well-sealed and properly designed foundation, builders can reduce the risk of termite infiltration. 4. Proper Drainage and Moisture Control Termites are attracted to moisture, so managing water around a structure is crucial for preventing infestations. Key moisture control strategies include: Proper Grading – Ensuring that the landscape slopes away from the foundation prevents water accumulation near the structure. Gutter Systems – Installing gutters and downspouts helps direct rainwater away from the foundation, reducing soil moisture levels. Ventilation in Crawl Spaces – Adequate airflow in crawl spaces prevents excess humidity, making the environment less attractive to termites. Controlling moisture helps protect the foundation while reducing conditions that attract termites. 5. Installation of Termite Barriers Physical termite barriers add an extra layer of protection by preventing termites from accessing the structure. Common types include: Stainless Steel Mesh Barriers – Placed beneath the foundation or around plumbing penetrations, these barriers block termite entry points. Sand or Crushed Rock Barriers – Certain soil compositions, such as coarse sand or crushed rock, make it difficult for termites to tunnel through. These barriers are particularly effective when combined with chemical treatments and other preventive measures. Post-Construction Termite Prevention and Maintenance Even with strong preventive measures during construction, ongoing maintenance is essential to keep termites at bay. Property owners should take the following steps to ensure long-term protection: Regular Inspections – Annual termite inspections help detect early signs of activity before significant damage occurs. Minimizing Wood-to-Soil Contact – Wooden structures, such as fence posts and deck supports, should be kept above ground and treated with a termite-resistant coating. Removing Wood Debris – Keeping the area around a building free of untreated wood, mulch, and other cellulose materials helps reduce termite attraction. Professional Monitoring Systems – Bait stations and monitoring systems can be installed around the perimeter of a building to track termite activity and prevent infestations. Routine inspections and maintenance are necessary to ensure that termite defenses remain effective over time. Why Preventive Measures Matter Ignoring termite prevention can lead to severe structural damage, costly repairs, and diminished property value. In South Louisiana, where termite populations thrive, taking proactive steps during the construction process is the best defense against infestations. By integrating termite-resistant materials, proper drainage, and ongoing maintenance, builders and property owners can protect their investments and extend the lifespan of their structures. Early planning and attention to detail make a significant difference in preventing termite damage. Prioritizing these measures during construction ensures that homes and commercial buildings remain structurally sound and protected against one of the most persistent threats in the region.
