Understanding the Behavior and Habits of Subterranean Termites

Termites, often referred to as silent destroyers, are insects that can cause extensive damage to wooden structures if left unchecked. Among the various types of termites, subterranean termites are one of the most common and destructive species. It is crucial to understand their behavior and habits to prevent and control infestations effectively. In this article, we will delve into the fascinating world of subterranean termites, exploring their behavior, habits, and answering some frequently asked questions.


Subterranean termites are highly social insects that live in large colonies. These colonies consist of different castes, each with specific duties and responsibilities. The three primary castes are workers, soldiers, and reproductive individuals.

Workers make up the majority of the termite colony. They are responsible for constructing tunnels, foraging for food, and taking care of the young termites. Workers are creamy-white in color and are blind, but possess a well-developed sense of touch and smell.

Soldiers have larger heads and powerful jaws compared to workers. Their primary responsibility is to defend the colony against potential threats, such as predators. Soldiers cannot feed themselves and rely on workers for sustenance.

Reproductive individuals are responsible for perpetuating the colony. They include the queen, king, and alates (winged termites). The queen is the largest termite in the colony and can lay thousands of eggs each day to ensure the colony's growth.


1. Foraging: Subterranean termites are constantly searching for food sources, mainly cellulose-based materials like wood. They construct mud tubes to protect themselves from predators and maintain a moist environment while foraging above ground.

2. Nesting: These termites build their nests underground, providing them with a safe and stable environment. The nests consist of interconnected tunnels and chambers, allowing the termites to travel and access food sources efficiently.

3. Moisture Dependence: Subterranean termites require moisture to survive. They are more prevalent in areas with high humidity levels or in structures with moisture problems. Moist wood is more susceptible to termite infestation.

4. Swarming: During the spring, reproductive termites emerge from their colonies in swarms. These winged termites, also known as alates, mate and establish new colonies. After mating, alates shed their wings and search for a suitable nesting site.

5. Destruction: Subterranean termites feed on cellulose, causing significant damage to wooden structures. They can weaken the structural integrity of buildings, leading to costly repairs if left untreated.


1. How can I identify a subterranean termite infestation?
Signs of infestation include mud tubes on walls or foundation, discarded wings near windows, sagging floors or doors, and hollow-sounding wood.

2. Are subterranean termites harmful to humans?
While termites do not directly harm humans, their presence can lead to extensive damage to homes and other structures.

3. How can I prevent subterranean termite infestation?
Prevention measures include reducing moisture sources, fixing leaks, removing wood-to-soil contact, and regular inspections by pest control professionals.

4. Can I treat a termite infestation myself?
DIY termite treatments are rarely effective. Professional assistance is recommended to ensure proper identification and effective treatment.

5. Are subterranean termites found in all climates?
Subterranean termites thrive in warm and humid climates. However, they can adapt to a wide range of environments.

6. How long does a subterranean termite colony live?
A well-established colony can survive for several years, with the queen potentially living for over a decade.

7. Can termites be eradicated completely?
Complete eradication of termites is challenging due to their widespread nature. However, effective pest control treatments can significantly reduce their population.

8. Are there natural methods to control subterranean termites?
While some natural remedies like orange oil and boric acid may have limited effectiveness, professional treatment is usually necessary for complete control.

9. How quickly do termites cause damage?
The rate of damage depends on various factors, including the termite species, colony size, and environmental conditions. However, significant damage can occur over several months or years.

10. Can termites be prevented in new construction?
Yes, preventive measures can be taken during construction, such as using termite-resistant building materials, implementing physical barriers, and applying chemical treatments.

In conclusion, understanding the behavior and habits of subterranean termites is essential for effective termite control. Being aware of their behavior patterns, nesting habits, and preventive measures can help homeowners protect their properties from these destructive insects. Regular inspections by professionals and prompt action upon detecting signs of infestation are vital to minimize damage and maintain the integrity of structures.
