Subterranean termites are a significant pest problem in Central and Eastern Florida, causing extensive damage to homes and businesses. Each year, termites are responsible for more than $500 million in damage in Florida alone. These pests feed on the cellulose found in wood and other organic materials, making them a constant threat to any structure with wood framing or support. Unfortunately, their presence often goes unnoticed for years, allowing the damage to accumulate without any visible signs. Homeowners may not realize the extent of the destruction until it becomes serious, such as when walls buckle, doors stick, or wooden floors sag.
How Subterranean Termites Go Unnoticed
Subterranean termites live underground, making it easy for them to infiltrate homes through cracks in foundations, gaps in utility conduits, or other small openings. They build extensive tunnel systems to travel from their nests to food sources. These tunnels, known as mud tubes, allow termites to move between the soil and the structure without being exposed to light or predators. Because they live and operate out of sight, the damage they cause can go unnoticed for years. By the time termites are spotted or signs of their activity become visible, such as blistered wood or hollowed-out beams, significant damage may already have occurred.
Subterranean termites play a crucial role in nature, acting as one of the primary decomposers of dead and decaying wood. While these insects are notorious for causing significant damage to homes and buildings, their ecological role in forests and other natural habitats is essential. Termites contribute to the breakdown of cellulose, the main component of wood, returning nutrients to the soil and aiding in the recycling of organic matter. In this way, subterranean termites help maintain the balance of ecosystems by facilitating the decomposition process and contributing to the nutrient cycle.
Subterranean Termites as Nature’s Decomposers
In their natural environments, subterranean termites primarily feed on dead or dying trees, logs, and other plant material that contains cellulose. Without termites and other decomposers, forests and ecosystems would become overwhelmed with dead plant material, inhibiting new growth. Termites break down this plant matter into smaller particles, which are then consumed by other microorganisms, further contributing to the nutrient cycle. This process enriches the soil, promoting healthier vegetation and supporting plant life.
Termites are particularly efficient at breaking down tough cellulose, which many other organisms cannot digest. Their ability to digest wood is due to a symbiotic relationship with microorganisms in their gut. These bacteria and protozoa produce enzymes that break down cellulose into simpler compounds, which the termites can then absorb as nutrients. By decomposing dead trees and other plant material, termites help prevent the accumulation of detritus, making room for new growth and maintaining the health of ecosystems.
Historical Evidence
Termites have been around for millions of years, with evidence of their existence dating back to the Cretaceous period, more than 100 million years ago. Fossilized termite nests and wood with termite damage have been found, showing that termites have long played their role as decomposers in ancient ecosystems. In ancient cultures, termites were often observed but not well understood. Some early texts from Egypt and Mesopotamia reference termites, noting their destructive potential when they infested stored wood or building materials.
The damage caused by termites also influenced the design of ancient buildings. In some regions, architects would raise structures on stone foundations to deter termites, as the insects typically avoid stone or other non-cellulose materials. Even the Greeks and Romans took note of termite infestations, and some ancient writings warned against storing wood near the ground, where termites might find it.
Consumption of Wood in Natural Habitats
While termites can cause extensive damage to man-made structures, the amount of wood they consume in nature is impressive. Estimates suggest that a single subterranean termite colony can consume about one pound of wood per day. Over the course of a year, this can total hundreds of pounds, depending on the size of the colony. Given that subterranean termite colonies can contain hundreds of thousands, or even millions, of termites, the collective amount of wood consumed by termites in forests each year is substantial. This consumption, while harmful in urban settings, is vital for the decomposition and renewal of forests.
The Life Cycle of Subterranean Termites
A subterranean termite colony consists of a caste system with distinct roles: workers, soldiers, and reproductives.
- Workers are responsible for feeding the colony, tending to the eggs, and building and maintaining tunnels.
- Soldiers protect the colony from threats, particularly ants.
- Reproductives include the king, queen, and alates (winged termites). The queen’s primary role is to lay eggs, ensuring the colony’s growth and survival.
A termite queen is created during the swarming process, when alates leave the colony to establish new ones. Once a male and female alate find each other, they shed their wings and burrow into the ground to start a new colony. The female becomes the queen and begins laying eggs, initially in small numbers, but as the colony matures, her egg production increases dramatically. The queen can live for several decades, producing millions of eggs over her lifetime.
If the queen dies, the colony may begin to collapse. However, some colonies are capable of producing secondary reproductives to continue reproduction and sustain the colony. Without a queen, the colony’s growth and stability are threatened, making it easier to control or eradicate.
Sentricon Termite Bait Stations: An Effective Solution
One of the most effective treatments against subterranean termites is the Sentricon Termite Bait Station, which uses an innovative approach to termite control. Sentricon relies on an insect growth regulator (IGR) called Recruit HD, which interferes with the termites’ molting process—a critical stage in their development. Molting is necessary for termites to grow and continue their life cycle, but when they consume the bait from a Sentricon station, the IGR stops them from molting, causing them to die. Without molting, the entire colony, including the queen, will eventually perish.
After termites consume the bait, it typically takes a few weeks for the effects to spread throughout the colony. Since termites share food through a process called trophallaxis, the bait is passed to other members of the colony, ensuring that the insect growth regulator affects the majority of the population.
How Sentricon Is Installed and Maintained
Sentricon is installed by placing bait stations in the soil around the perimeter of a home or building. These stations are placed strategically to intercept termites as they forage for food. Once installed, the stations are monitored regularly by pest control professionals, who check for termite activity and replenish the bait as needed. The process is non-invasive, and there is no need for drilling or trenching, unlike traditional liquid treatments.
Environmentally Friendly Approach
Sentricon is considered environmentally friendly compared to liquid insecticides, which can leach into the soil and potentially affect non-target organisms. The Sentricon system is designed to target only termites, and because it uses a growth regulator rather than a broad-spectrum insecticide, it minimizes the environmental impact. The bait stations are contained and monitored, reducing the risk of harmful chemicals spreading into the surrounding ecosystem.
The Process for Using Liquid Termiticide
A liquid termiticide treatment is a common method for protecting homes from subterranean termites. This process involves creating a chemical barrier around the foundation of the home to prevent termites from entering. Here’s how it works:
1. Inspection: The pest control technician begins with a thorough inspection to identify termite activity and determine the best treatment areas. This includes locating points of entry, such as cracks in the foundation or around plumbing lines.
2. Trenching and Drilling:
- Trenching: The technician digs a shallow trench around the perimeter of the home, typically about 6 inches deep. The trench allows the liquid termiticide to reach the soil where termites travel.
- Drilling: In areas where there are concrete slabs, driveways, or patios adjacent to the house, the technician must drill small holes (about 1/2 inch in diameter) through the concrete to apply the liquid termiticide beneath the surface. These holes are typically spaced about 12-18 inches apart.
3. Application of the Termiticide: Once the trench is dug and the necessary holes are drilled, the liquid termiticide is applied. The technician injects the chemical deep into the soil to create a continuous barrier. In the drilled areas, the termiticide is pumped into the ground beneath the concrete.
4. Filling Trenches and Sealing Holes: After the application, the trenches are filled back in with soil, and the drilled holes in the concrete are sealed. This restores the landscape or flooring to its original condition.
5. Monitoring: Liquid treatments often come with a warranty, so technicians may periodically inspect the property to ensure termites are not breaching the barrier.
Advantages and Disadvantages of Sentricon Bait Stations vs. Liquid Termiticide
Sentricon Bait Stations
Advantages:
- Environmentally Friendly: Sentricon uses targeted termite bait rather than spreading chemicals in the soil. The bait system only affects termites, reducing the risk of harming other wildlife or plants.
- Non-invasive: There is no need to drill through concrete or dig trenches around the home, which means less disruption to the property.
- Long-lasting Protection: Sentricon bait stations are regularly monitored and can continue to protect the home for years without degrading.
- Kills the Entire Colony: Sentricon targets the entire termite colony, including the queen, by disrupting the molting process, which eventually leads to the colony’s collapse.
Liquid Termiticide
Disadvantages:
- Invasive Installation: Drilling through concrete and trenching around the home can be disruptive to landscaping and patios.
- Degrades Over Time: Liquid termiticides can break down in the soil due to moisture, heat, and microbial activity, meaning the protection may degrade over time and require reapplication.
- Environmental Concerns: Chemicals may leach into the soil and potentially affect non-target organisms, including beneficial insects and plants.
Both Sentricon bait stations and liquid termiticide treatments have their advantages and disadvantages. Sentricon offers a long-term, eco-friendly solution with less disruption, but it works more slowly and requires monitoring. Liquid treatments, while fast-acting and highly effective, can degrade over time and involve more invasive installation procedures. The best choice often depends on the homeowner’s specific needs, the severity of the termite problem, and environmental considerations.
