Formosan Subterranean Termites

If you’ve spent any time on social media lately, you’ve probably seen videos of massive termite swarms taking over porches, neighborhoods, and businesses along coastal counties. Maybe you’ve even experienced a swarm firsthand! 

These termites are not the same as the native termites found in Mississippi. Formosan subterranean termites are an invasive species found mainly in the southern half of the state, primarily in coastal counties. They are active primarily at night in May and June, especially after a rain. 

So, how are these termites different from native termites? There are clear signs:

Native Termites:

• Small in size
• Black bodies
• White wings
• Active during daytime

Formosan Subterranean Termites:

• Large in size
• Brown bodies
• Amber-colored wings
• Active at night, especially after a rain

If you’re still not sure about how to tell the two apart, the biggest difference is that Formosan termites are highly attracted to light. This is why they often swarm around porches, windows, or buildings where lights are. 

Sometimes these termites can fly into homes or crawl under doors. If you live in the southern, coastal counties where they are common, it’s recommended to turn off outdoor lighting and close your blinds at night to reduce attraction. Should you worry if you find them in your home? No! The good news is that finding swarmers in your home does not mean your home is infested. In most cases, termites that fly inside will die because they almost always need soil to start a colony. It is an indicator that there are colonies nearby though. 

Formosan termites are established in 26 counties in Mississippi. Homeowners are encouraged to maintain an annual termite contract with a reputable pest management company to keep an eye out for termites in your home. 

If you believe you’ve found Formosan termites outside of their known range, especially if you live in the central and northern parts of Mississippi, please fill out this form or contact the Mississippi State University Extension Insect ID Lab. This will be a huge help as we track their invasive spread over the state!
