What Are Termites?
March 08, 2023 - Termites
Termites are small, soft-bodied insects that feed on wood and other cellulose-containing materials. They live in colonies and are known for their ability to cause significant damage to wooden structures and other materials. There are several different types of termites, including subterranean, drywood, and dampwood termites, each with their unique behaviors and characteristics.
What Is The Significance Of Termites?
Termites are significant for several reasons. Due to the crucial role they fill in the ecosystem by breaking down dead wood and other organic matter, which helps to enrich the soil and promote new growth, termites are capable of causing extensive damage to wooden structures and other materials. This can result in significant financial losses. Termites can serve as indicators of environmental health, as changes in their populations or behavior can signal underlying issues in the ecosystem. The study of termites has led to important scientific discoveries and advancements in fields such as biomimicry and biotechnology.
What Are The Three Main Kinds Of Termites?
There are three main types of termites: subterranean, drywood, and dampwood termites.
Subterranean termites live in the soil and build their nests underground, which can extend to over 300 feet in length. They require moisture to survive and usually enter buildings through wood that comes into contact with the soil. Subterranean termites are the most destructive of all the termite species, causing damage worth billions of dollars each year. They are also the most common type of termite found in the United States.
As their name suggests, drywood termites do not require as much moisture as subterranean termites and can survive in relatively dry environments. They infest dry, sound wood, including furniture, framing, and flooring. Unlike subterranean termites, drywood termites don't build mud tubes or nests in the soil. Instead, they build their colonies inside the wood they infest, making them harder to detect and control.
Dampwood termites thrive in moist wood, such as decaying logs and stumps, and are less common than subterranean and drywood termites. They prefer wood that is in direct contact with the ground or close to a source of moisture. Dampwood termites do not usually infest buildings unless there is a significant moisture problem.
Each type of termite has its unique behaviors, characteristics, and preferred habitats, which affect the way they are treated and controlled. Learn more: What types of termites are there?
What Is The Life Cycle Of Termites?
The life cycle of termites typically includes three stages: egg, nymph, and adult.
Termite eggs are small, oval-shaped, and translucent or white in color. The size of a termite egg varies depending on the species, but it's usually less than one millimeter in length. Termite eggs are typically laid in clusters, and they are tended by worker termites until they hatch. The queen termite is responsible for laying eggs, and she can lay thousands of eggs per day. The eggs hatch into larvae, which then molt into nymphs before becoming adult termites. The time it takes for termite eggs to hatch depends on the temperature and humidity levels in the colony, but it usually takes a few weeks. Termite eggs are an essential part of the termite life cycle, and their successful hatching is critical to the growth and survival of the colony.
Termite nymphs are young termites that have recently hatched from eggs. They are small, pale, and soft-bodied, and they do not have wings. Nymphs are responsible for performing many tasks in the colony, including caring for the eggs, tending to the young, and building and maintaining the nest. As they grow, nymphs go through a series of molts, shedding their exoskeleton and growing larger with each molt. After several molts, the nymphs develop into adult termites. The time it takes for a termite nymph to develop into an adult varies depending on the species, but it can take anywhere from a few weeks to a few years. Nymphs play a crucial role in the termite colony and are responsible for ensuring the growth and survival of the colony.
Termite adults, also known as "reproductives" or "swarmers," are responsible for reproducing and establishing new colonies. They have two pairs of wings that are equal in size, a broad waist, and straight, bead-like antennae. Termite adults are typically black or brown in color, and their bodies can range in size from 1/4 inch to 1 inch in length, depending on the species.
Once a termite colony reaches maturity, it will produce winged adults that will leave the colony in swarms to mate and establish new colonies. After the swarming flight, the male and female termites shed their wings and start to burrow into soil or wood to begin their new colony. The queen then begins to lay eggs, and the cycle starts anew. Termite adults do not feed on wood, but instead rely on other members of the colony to provide them with food.
The exact length of the termite life cycle can vary depending on the species and environmental conditions. For example, subterranean termites can reach maturity in as little as two years, while drywood termites can take several years to reach maturity. Additionally, the size of the colony can also affect the rate of growth and development.
What Different Roles Are There In A Termite Colony?
Termites are social insects that live in colonies with a caste system made up of different types of individuals. The different castes of termites are:
Termite workers are the most numerous and important caste in a termite colony. They are responsible for carrying out most of the tasks necessary for the survival and growth of the colony.
Termite workers are usually small, pale in color, and wingless. They are blind and spend their entire lives in the dark, humid environment of the colony. Their primary role is to gather food, feed the other members of the colony, and care for the young. They also build and maintain the nest, tunnel through soil and wood, and defend the colony against intruders.
Termite workers are able to digest cellulose, the main component of wood, with the help of symbiotic protozoa in their gut. They feed on a variety of materials, including wood, paper, and fabric. In order to locate food sources, they communicate with each other using chemical signals called pheromones.
Termite workers are not capable of reproduction and do not have functional wings. They rely on the reproductive caste, consisting of the king and queen, to produce offspring and maintain the colony's population. Termite workers can live for several years, and their constant activity and hard work are essential to the success and survival of the colony.
Termite soldiers are one of the three main castes in a termite colony, along with workers and reproductive termites. They are responsible for defending the colony against predators and other threats.
Soldiers have larger heads and mandibles than workers, which they use to defend the colony. They also have a hardened exoskeleton and are typically darker in color than workers or reproductive termites.
There are different types of termite soldiers depending on the species, but in general, they can be classified as either mandibulate or nasute. Mandibulate soldiers have large, powerful mandibles that they use to crush and attack predators. Nasute soldiers, on the other hand, have long snouts that they use to spray a sticky defensive substance at attackers.
Soldiers are sterile and cannot reproduce. Instead, their sole purpose is to defend the colony and its members, including the queen and workers who are responsible for feeding and caring for the colony.
Reproductive termites, also known as alates or swarmers, are responsible for starting new termite colonies. They have wings and are the only members of the termite colony that can reproduce. (Learn more: Do termites have wings?) When conditions are right, such as during warm and humid weather, these termites will swarm and mate. After mating, they will shed their wings and seek out a suitable location to start a new colony. The female reproductive termites, known as the queen, will lay eggs and the new colony will begin to grow. The reproductive termites are larger than the worker and soldier termites, and they have dark brown or black bodies with straight antennae.
Not all termite species have the same castes, and some may have additional or different types of castes depending on their behavior and habitat.
What Are The Behaviors Of Termites?
Termites exhibit a variety of behaviors that are essential to the functioning of their colonies. Here are some of the most important ones:
- Nesting: Termites build elaborate nests that serve as their homes and provide protection from the outside environment.
- Feeding: Termites are primarily cellulose feeders, meaning they feed on wood, paper, and other plant-based materials. They use their strong jaws and digestive enzymes to break down the cellulose into simpler compounds that can be absorbed by their bodies.
- Communication: Termites communicate with one another using a variety of chemical signals, including pheromones. These signals help them to coordinate their activities and respond to changes in their environment.
- Social organization: Termites have a complex social structure, with different castes of individuals specialized for different tasks. For example, workers are responsible for foraging, feeding the other members of the colony, and caring for the young, while soldiers are responsible for defending the colony from predators.
- Reproduction: Termite colonies produce reproductive individuals known as alates, which have wings and can fly to start new colonies. Once they find a suitable mate, they shed their wings and begin to establish a new nest.
Termites exhibit highly organized and coordinated behaviors that allow them to function as successful colonies.
How To Find Signs Of Termites
Termites are small, white, and soft-bodied insects that often go unnoticed until they have caused significant damage to structures or objects. Here are some tips on how to identify termites:
- Look for termite swarms - Swarming termites are a group of winged termites that fly in search of a new location to start a colony. Swarms usually occur in the spring or early summer and can be a sign of an active termite infestation.
- Inspect wooden structures - Termites feed on cellulose, which is found in wood, and can cause significant damage if left unchecked. Look for mud tubes or tunnels made of soil and saliva that termites use to travel from their nests to food sources. Also, look for hollowed-out or damaged wood, especially in areas that are damp or have poor ventilation.
- Check for termite droppings - Termites leave behind tiny pellets of frass, which are their droppings. These pellets look like small grains of sand or sawdust and can be found near the damaged wood.
- Listen for clicking sounds - Soldier termites make a clicking sound when disturbed, and this can be heard when tapping on a piece of infested wood.
- Look for discarded wings - After swarming, termites shed their wings, which can often be found near windowsills, door frames, or light fixtures.
- Get a professional inspection - If you suspect you have termites but are unsure, it's best to contact a licensed pest control professional to conduct a thorough inspection. They have the tools and expertise to identify the presence of termites and recommend the best course of action.

Termite Control Methods
Termite control is the process of managing or eliminating termite infestations in a building or property. There are several methods of termite control. To effectively control termites, it's essential to identify the type of termite and extent of the infestation to determine the most effective treatment method. Regular inspections and preventative measures, such as reducing moisture and eliminating food sources, are also important in termite control.
Professional Termite Inspections
Professional termite inspections are conducted by licensed pest control professionals who are trained to identify the signs of termite activity. During an inspection, the technician will thoroughly inspect the property, both inside and outside, including the foundation, walls, attic, basement, and crawl spaces. They may use specialized equipment such as moisture meters and thermal imaging cameras to detect any termite activity or damage that may not be visible to the naked eye. After the inspection, the technician will provide a report detailing any termite activity or damage found, as well as recommendations for treatment and prevention. Professional termite inspections are recommended at least once a year to catch any potential infestations early and prevent costly damage.
Liquid Termite Treatments
Liquid termite treatments involve applying a termiticide to the soil around a building's foundation or in areas where termites are present. The termiticide creates a barrier that prevents termites from entering the structure and kills any termites that come into contact with it. The treatment typically involves drilling small holes in the foundation or slab and injecting the termiticide into the soil. The termiticide then spreads through the soil to create a continuous barrier. This method is one of the most effective ways to control termites and prevent future infestations. It is important to have a professional pest control company perform the liquid termite treatment to ensure proper application and effectiveness.
Installing Termite Bait Stations
Termite bait stations are a type of termite control method that involve placing bait stations around the perimeter of a home or building. These stations contain a slow-acting poison that is consumed by the termites, who then carry it back to the colony and share it with other termites. Over time, the poison can eliminate the entire colony.
Bait stations are designed to be non-invasive and do not require drilling into walls or foundations. They are typically installed in the ground around the home, with the idea being that the termites will be attracted to the bait and leave the structure alone.
Bait stations are generally considered to be a more environmentally friendly option than liquid treatments, as they use a smaller amount of pesticide and target only the termite colony rather than the entire area surrounding the home. However, they can take longer to achieve complete colony elimination compared to other methods. Regular monitoring and maintenance of bait stations is necessary to ensure their effectiveness.
Wood Treatments With Borates
Treating wood with borates is a common method of preventing termite infestation. Borates are naturally occurring mineral salts that can be dissolved in water and applied to wood. When the borates penetrate the wood, they create a barrier that prevents termites from feeding on the wood. This method is effective because it not only kills existing termites but also prevents future infestations. Borate-treated wood is commonly used for framing, flooring, and other structural components in buildings. However, it is important to note that borate treatments are typically not effective for existing termite infestations and are best used as a preventative measure. Professional pest control companies can apply borate treatments to wood during construction or as a retrofit to an existing structure.
