The Complete Guide to Termite Behavior and Swarming in Louisiana
Louisiana’s warm and humid climate makes it a prime location for termite activity, with infestations causing significant structural damage each year. This guide provides an in-depth look at termite behavior, including their diet, how they spread, their swarming habits, and strategies for preventing infestations. By understanding these key factors, homeowners can take proactive steps to protect their properties from costly termite damage.
Termite Diet and Behavior
Why Do Termites Eat Wood?
Termites are detritivores, meaning they consume decomposing plant material. Their primary food source is cellulose, an organic fiber found in wood, paper, and plant matter. Termites digest cellulose using specialized microorganisms in their guts, allowing them to break down this tough material. Unfortunately, this dietary requirement leads them to consume structural wood in homes, causing significant damage over time. Learn more about termite diet from the Louisiana State University Agricultural Center.
Can Termites Survive on Water Alone?
While termites require moisture to survive, they also need cellulose for proper nutrition. Some species can persist for short periods with only water, but a lack of cellulose would eventually lead to colony collapse.
What Types of Wood Do Termites Eat?
Termites consume various dead wood types, but some species also feed on living trees. Their diet includes:
- Structural lumber
- Paper and cardboard
- Drywall
- Bark and leaves
- Plastic (if cellulose is present)
Worker termites distribute digested cellulose to the colony through a mouth-to-mouth feeding process, ensuring that immature termites, soldiers, and reproductives receive essential nutrients.
How Termites Spread
How Do Termites Enter Homes?
Subterranean termites, the most common species in Louisiana, construct mud tubes made from soil, wood, and grass to travel between their underground nests and food sources. These tubes provide moisture and protection, allowing them to invade homes undetected.
Common entry points include:
- Wooden structures in contact with the soil (decks, door frames, and siding)
- Cracks in foundations and walls
- Openings around plumbing and wiring

Do Termites Spread Quickly?
Yes, termites multiply rapidly. Once inside, they establish new tunnels and colonies, which can lead to full infestations in just a few weeks. Since termites work silently, homeowners often don't realize there's a problem until significant damage has occurred.
Termite Swarming and Reproduction
Why Do Termites Swarm?
Swarming is the process by which termites establish new colonies. When a termite colony matures, it produces alates (winged reproductive termites) that leave the nest to mate and find new nesting locations. This ensures the species' survival and expansion.
When Do Termites Swarm in Louisiana?
Termites swarm seasonally, typically in spring and early summer, when humidity is high. Warm temperatures and recent rainfall create ideal conditions for swarming activity.
What Happens When Termites Lose Their Wings?
Once a male and female pair up, they shed their wings and seek a secluded, moist environment to establish a new colony. If they fail to find suitable conditions, they die within hours due to dehydration.
How Many Termites Are in a Swarm?
Swarm sizes vary based on colony maturity, ranging from a few individuals to millions emerging simultaneously across multiple colonies. Louisiana's warm and humid climate allows for massive termite swarms that can be seen throughout the state.
Are Termites Attracted to Light?
Yes, alates are drawn to light sources, making swarming termites visible around outdoor lights, windows, and street lamps. This behavior presents a unique opportunity for homeowners to detect potential infestations. If you notice swarming termites indoors, it's a strong indicator of an active infestation within your home. More details on termite swarming can be found in the Environmental Protection Agency’s Termite Guide.
Termite Nesting and Infestations
Why Do Termites Build Nests Inside Homes?
Certain termite species, such as Formosan termites, are capable of building carton nests within walls, attics, and other hidden areas. Unlike most subterranean termites that require contact with soil, Formosan termites can establish aerial colonies, making them particularly difficult to detect and eradicate.
Signs of a Termite Infestation
Homeowners should look for the following signs:
- Mud tubes on foundations, porches, and tree trunks
- Discarded wings near windowsills or doorways
- Hollow-sounding wood when tapped
- Soft or warped floorboards
- Clicking noises inside walls (termites communicate by banging their heads)
- Accumulated dried mud around doors and windows
How to Prevent Termite Infestations
Preventing termites involves eliminating moisture sources and sealing potential entry points. Effective prevention measures include:
- Ensuring proper drainage around the foundation
- Keeping firewood and mulch away from the home
- Sealing cracks and gaps in walls and foundations
- Using termite-resistant building materials
- Scheduling annual professional termite inspections
Homeowners can protect their properties from costly infestations by understanding termite behavior and taking proactive steps. Regular inspections and professional pest control in New Orleans are essential, as termites thrive year-round.
