Drywood termites are relatively small compared to other termite species. The workers, responsible for feeding and nest maintenance, measure around 3/8 to 1/2 inch in length. Soldiers, tasked with defending the colony, have larger, elongated heads with powerful mandibles. Reproductive termites, also known as swarmers or alates, have wings and can vary in size.
B. Signs of Drywood Termite Infestation
Detecting signs of drywood termite infestation early is crucial in preventing widespread damage. Homeowners should be vigilant and look for the following indicators:
Presence of Termite Pellets
Drywood termites produce tiny, hexagonal-shaped pellets, commonly referred to as “termite frass.” These pellets are the excrement of the termites and are usually found beneath infested wood or in piles near termite exit holes.
Swarmers, or reproductive termites, shed their wings after finding a new site for establishing a colony. Discarded wings near windowsills, doors, or other entry points are a clear indication of termite activity.
Drywood termites tunnel through wood, creating chambers and galleries for nesting and feeding. Look for blistering, sagging, or hollow-sounding wood, as well as small holes on the surface.
III. Geographic Distribution
Drywood termites have a global distribution, although their prevalence varies across different regions. Understanding the geographic distribution of these pests can help homeowners assess the likelihood of encountering infestations.
A. Global Distribution of Drywood Termites
Drywood termites are found in various parts of the world, including North America, South America, Europe, Africa, Asia, and Australia. Their distribution is influenced by climate, as they tend to thrive in warmer regions with lower humidity levels.

In the United States, drywood termites are particularly prevalent in coastal areas and southern states with a warmer climate. States such as California, Florida, Texas, and Hawaii have reported significant drywood termite infestations. However, it is important to note that these pests can be found in other regions as well, even if they are less common.
IV. Life Cycle of Drywood Termites
Understanding the life cycle of drywood termites is essential for effective control strategies. By knowing the different stages and durations of their life cycle, homeowners can target vulnerable points and disrupt the reproductive cycle.
A. Stages in the Life Cycle of Drywood Termites
The life cycle of drywood termites consists of three main stages:
- Egg Stage: After mating, the reproductive termites lay eggs within the galleries of the infested wood. These eggs hatch into nymphs.
- Nymph Stage: Nymphs are young termites that undergo a series of molts, gradually developing into adult termites. They assist in expanding the colony and contribute to the damage inflicted on the wooden structure.
- Adult Stage: Once the nymphs complete their development, they become adult termites. Adults are responsible for reproduction, foraging for food, and expanding the colony.
B. Duration of Each Life Stage
The duration of each life stage in drywood termites can vary depending on environmental conditions and termite species. On average, the egg stage lasts around two weeks, while the nymph stage may span several months. The adult stage can last for years, with reproductive termites periodically swarming to establish new colonies.
V. Damage Caused by Drywood Termites
Drywood termites pose a significant threat to wooden structures, causing extensive damage if left untreated. Understanding the potential consequences of an infestation emphasizes the importance of swift action.

How can you tell if you have drywood termites?
Detecting a drywood termite infestation early is crucial in preventing extensive damage. Here are some signs to look out for:
- Termite Pellets: Drywood termites produce tiny, hexagonal-shaped pellets, known as “termite frass.” These pellets are the fecal matter of the termites and are typically expelled from their galleries and accumulated near the infested wood. The presence of termite pellets is a clear indication of an active infestation.
- Discarded Wings: During their swarming phase, reproductive termites shed their wings after finding a new site for establishing a colony. Finding discarded wings near windowsills, doors, or other entry points can indicate the presence of drywood termites.
- Wood Damage: Drywood termites tunnel through the wood, creating chambers and galleries for nesting and feeding. This activity can result in blistering or hollow-sounding wood, small holes on the surface, or even structural weaknesses. Tapping or knocking on the infested wood may produce a distinct hollow sound.
If you suspect a drywood termite infestation based on these signs, it is crucial to contact a professional pest control service for a thorough inspection and confirmation.
How do drywood termites start?
Drywood termite colonies typically start when reproductive termites, also known as alates or swarmers, leave their existing colony to establish new ones. These winged termites fly out in large numbers during the swarming season, which usually occurs in the spring or summer.
The reproductive termites seek out suitable wood sources, such as exposed or untreated wooden structures, furniture, or dead trees. Once they find a suitable site, they shed their wings and pair up to start a new colony. The pair, consisting of a king and a queen, excavates a small chamber in the wood and begins to lay eggs. Over time, as the eggs hatch and the nymphs develop into workers and soldiers, the colony grows and expands within the infested wood.
Drywood termites can also be introduced to a structure through infested wooden items, such as furniture or lumber. These termites can remain hidden within the wood, slowly multiplying and causing damage over time.
Do drywood termites swarm at night?
Drywood termites typically swarm during the daytime, especially in the warmer months. Swarming is a reproductive behavior exhibited by the winged reproductive termites when they leave their existing colony to mate and establish new colonies. They are attracted to light sources and may be seen flying around windows, doors, or other openings.
While drywood termites primarily swarm during the day, it is not uncommon for swarming to occur in the early evening or at twilight when there is still sufficient daylight. Swarming activity is influenced by environmental factors such as temperature, humidity, and light conditions.
Do drywood termites eat wood?
Yes, drywood termites feed on wood as their primary source of nutrition. They extract cellulose, the main component of wood, for sustenance. Unlike subterranean termites that rely on moisture and soil contact, drywood termites can directly infest dry wood without needing contact with the ground.
Drywood termites excavate tunnels and galleries within the wood, consuming the cellulose-rich material as they create their nests. Over time, their feeding activity weakens the wood structure and can lead to significant damage if left untreated.
How does vinegar get rid of drywood termites?
Vinegar is often suggested as a natural remedy for eliminating termites; however, its effectiveness in controlling drywood termites is limited. While vinegar has some acidic properties that can be detrimental to termites, it is not a reliable standalone solution for eradicating an infestation.
Vinegar can be used as a household cleaner to wipe off termite trails or remove surface frass. However, it does not penetrate deep into the wood or reach the hidden galleries where the termites reside. Drywood termite infestations typically require targeted treatments that directly address the colonies within the wood.
To effectively control drywood termites, it is advisable to consult with professional pest control services that can provide appropriate treatment methods based on the extent of the infestation and the specific circumstances.
