What Is a Termite Mound? Structure, Height, and Uses
A termite mound is an above-ground structure built by social termite colonies from soil, saliva, and feces, serving as a climate-regulated nest that supports colony respiration, temperature control, and protection. Mounds range from small domes under a meter to towering structures several meters high, and they function as ecosystem engineers that alter soil fertility, water movement, and plant communities. This article explains mound composition, typical heights, internal architecture, and the practical uses of mounds in agriculture, construction, and ecological research, with attention to what mound presence near a house means for property management.
What Defines a Termite Mound
Termite mounds are constructed by eusocial insects in the order Blattodea, family Termitidae and related families. Several species across Africa, Asia, Australia, and South America collectively construct large, meter-sized, porous mound structures that regulate mound temperature, humidity, and gas concentrations [4]. The mound is not a random pile of dirt but a functional extension of the colony, built through the coordinated action of workers that carry soil particles from below ground and cement them with saliva and fecal material.
The term "mound" applies specifically to epigeal nests, meaning nests built above ground level. Subterranean termites that nest entirely below the surface do not produce mounds, although they may create mud tubes on foundations and walls. Mound-building species belong to multiple functional groups, including fungus-farming Macrotermitinae, soil-feeding Termitidae, and wood-feeding species such as Coptotermes and Nasutitermes [7][11]. The functional group determines mound architecture, soil source, and the internal organization of chambers and galleries.
Animal architecture of this type is widespread taxonomically, and termite mounds are among the most prominent examples, rivaling human skyscrapers in size relative to the body size of the architects [9]. The mound is a product of collective behavior without a central blueprint, emerging from local interactions between termites and their physical environment [4].
Mound Composition and Building Materials
Termite mounds are composed primarily of soil particles selected and transported by worker termites. The exact composition depends on the local soil type, the termite species, and the depth from which soil is excavated. In the Colombian Amazon, soil-feeding termites such as Patawatermes turricola construct mounds that significantly alter soil properties compared with unmodified topsoil [11]. Mound soil in that region showed higher macro-porosity, greater aggregate stability, and higher concentrations of cations, available phosphorus, and organic carbon than surrounding topsoil [11].
The binding agents in mound soil include termite saliva, which contains polysaccharides and proteins, and fecal material that acts as a cement. These organic binders give mound soil its characteristic hardness and resistance to erosion. The result is a biogenic aggregate structure distinct from the surrounding soil matrix [10]. Termites form unique soil biogenic aggregates and resource heterogeneity patches that affect microbial community structure, extracellular enzyme activity, and soil physicochemical properties [10].
Mound soil is not uniform. The outer wall is typically denser and harder than the inner core, which contains the nursery, royal cell, and fungus gardens in fungus-growing species. The outer wall protects against predators and weather, while the inner structure manages airflow and humidity. In soil-feeding mounds, the outer wall showed higher weighted mean diameter for aggregate stability (3.88 mm) compared with unmodified topsoil (3.57 mm), and macro-porosity was higher in the mound (18.49 percent versus 11.47 percent) [11].
Internal Architecture and Ventilation System
The interior of a termite mound contains a network of chambers and galleries that serve distinct functions. The central nest area holds the queen, king, brood, and workers. In fungus-farming species, specialized chambers house fungus gardens that digest plant material. Peripheral chambers and tunnels connect the nest to foraging areas and manage airflow.
The ventilation system of termite mounds combines internal main and attached chambers, a configuration that maintains a stable internal environment for large-volume structures [3]. This passive ventilation system relies on the porous mound wall, the chimney-like central structure, and the temperature gradient between the mound interior and the outside air. Wind passing over the mound surface creates pressure differences that draw air through the porous walls, while warm air rising from the nest creates a buoyancy-driven flow that exhausts carbon dioxide and draws in oxygen [3][6].
Research on mound climate control has used X-ray tomography and flow field simulations to understand how mound properties control ventilation and thermoregulation [6]. These methods reveal the three-dimensional structure of chambers and tunnels without destroying the mound, allowing researchers to model airflow patterns and temperature distribution. The mound environment, including internal structure and external factors such as temperature and season, can influence gas exchange between the mound and the atmosphere [7].
The internal environment also supports microbial communities that affect mound function. Termite mounds host bacterial communities that differ from surrounding soils, and these communities participate in nutrient cycling and greenhouse gas dynamics [25][27]. In methane-emitting species, mound methanotrophs can oxidize methane before it reaches the atmosphere, although the effect varies by species and environmental conditions [7].
Typical Mound Heights and Dimensions
Termite mound height varies widely by species, soil type, climate, and colony age. Small mounds built by soil-feeding termites may be less than 30 centimeters tall, while large mounds built by Macrotermes species in African savannas can exceed 3 meters in height and 10 meters in diameter at the base. The largest mounds are built by fungus-farming termites, which require substantial nest volume to support fungus gardens and large colony populations.
Mound volume correlates with colony size and age. A mature Macrotermes mound may contain millions of workers and represent decades of construction activity. The mound grows as the colony expands, with workers adding soil to the outer surface and excavating new chambers inside. Mound morphology is not fixed but responds to environmental conditions, including external temperature oscillations and internal odor concentrations [4].
In northern Australia, UAV laser scanning detected an average of eight mounds per hectare in a woodland savanna site, with mound height and volume extracted from the point cloud data [19]. The detection rate was 81 percent in high-resolution data (1800 points per square meter) and 72 percent in lower-resolution data (680 points per square meter) [19]. This study demonstrates that mound dimensions can be measured remotely, providing a scalable method for monitoring mound populations across large areas.
Compass termites in northern Australia build wedge-shaped mounds oriented north-south, with the broad face oriented to the east and west. The shape of compass termite mounds has biological significance related to temperature regulation, with the thin north-south profile minimizing midday solar exposure and the broad east-west faces capturing morning and afternoon sun [22]. These mounds can reach 3 to 4 meters in height but are only 1 to 2 meters wide.
Mound Functions Within the Colony
The mound serves multiple functions for the termite colony. Primary among these is climate regulation. The mound buffers the nest against external temperature fluctuations, maintaining the narrow temperature range required for brood development and fungus growth. In savanna ecosystems, shading from vegetation and the mound structure itself regulate internal temperature [5].
Gas exchange is a second critical function. Termites produce carbon dioxide through respiration and, in some species, methane through digestion. The porous mound wall allows these gases to diffuse outward while oxygen diffuses inward. The ventilation system enhances this exchange, particularly in large mounds where diffusion alone would be insufficient [3][6].
The mound also provides defense against predators and environmental stress. The hard outer wall resists digging by aardvarks, pangolins, and other predators, while the internal maze of tunnels confuses intruders. The mound elevates the nest above flood level in seasonally inundated areas, protecting the colony during wet seasons [26].
Mound-building activity modifies the surrounding environment. Termite mounds create resource heterogeneity patches that affect plant growth, community composition, and vegetation productivity [10]. In savannas, mounds support distinct plant communities because mound soil has higher nutrient concentrations and better water infiltration than surrounding soils. Trees such as Pterocarpus erinaceus in West Africa are found near termite mounds, with 21 percent of inventoried trees in the Sahelian zone and 13 percent in the Sudanian zone growing close to an anthill [23].
Mound Soil Fertility and Agricultural Uses
Termite mound soil is recognized for its fertility and is used in agriculture as a soil amendment and potting medium. The unique physicochemical and biochemical properties of mound soil make it highly fertile [16]. A study of potting media using mound soil from Odontotermes obesus found that a mixture of termite mound soil, sand, and farmyard manure in a 1:1:2 ratio produced the best results for pH (7.15), organic carbon (2.13 percent), available nitrogen (526.02 kg per hectare), available phosphorus (56.60 kg per hectare), and available potassium (708.19 kg per hectare) [16].
Mound soil improves soil physical properties as well as chemical fertility. In the Colombian Amazon, mound soil showed higher macro-porosity and aggregate stability than surrounding topsoil, improving water infiltration and root penetration [11]. The higher organic carbon content in mound soil (27.1 g per kg versus 23.3 g per kg in surrounding soil) supports microbial activity and nutrient cycling [11].
Farmers in tropical regions collect mound soil for use in crop production, particularly in areas with poor, acidic soils. The mound soil acts as a fertility amendment, providing nutrients and improving soil structure [10]. However, mound soil should be used judiciously because the nutrient content varies by termite species, soil type, and mound age. Testing mound soil before large-scale application is recommended to match nutrient supply to crop demand.
Termites as Poultry Feed
Termites are harvested and used as poultry feed in several regions of Africa and Asia. In Burkina Faso, poultry farmers collect termites from mounds and use them as a protein supplement for chickens. A study identified twenty termite species used in poultry feed across eight regions of Burkina Faso, belonging to two families, six subfamilies, and thirteen genera [13]. The largest number of species, eleven, was collected in the Cascades region [13].
Poultry farmers recognize termites by the shape, size, and color of the insects, by the termite mounds, and often by the location of the nest [13]. This indigenous knowledge allows farmers to locate and harvest termites efficiently. The most commonly used species belong to the family Termitidae, including the subfamilies Macrotermitinae, Nasutitermitinae, and Cubitermitinae [13].
Termites provide a high-protein feed source that is locally available and requires no purchased inputs. For smallholder poultry producers, termite harvesting can reduce feed costs and improve bird growth. However, sustainable harvesting practices are important to avoid depleting local termite populations. Farmers should rotate harvesting sites and avoid destroying entire mounds, which can take years to rebuild.
Construction Materials From Mound Soil
Termite mound soil has been used as a construction material for centuries. In Gambella, Ethiopia, the community uses indigenous knowledge of mixing termite mound soil with locally available straw to build mud houses [17]. Houses constructed with termite mounds are comparatively stronger than those prepared with other soils, but they have durability issues due to shrinkage cracks that require regular maintenance [17].
Research on adobe blocks made with termite mound soil found that adobe prepared with mound soil, 1.5 percent straw, and 2.5 percent binder provided excellent strength and durability, with a compressive strength of 2.6 MPa [17]. The adobe blocks showed reduced shrinkage (17 percent), low initial rate of absorption (0.29), and low water absorption (0.26) [17]. These results indicate that adobe is a sustainable solution for house construction in regions where termite mound soil is available.
In eastern Nigeria, researchers have modeled the compressive strength of concretes incorporating termite mound soil using multi-layer perceptron networks [18]. This work aims to predict the performance of mound soil as a partial replacement for conventional construction materials, potentially reducing the cost and environmental impact of concrete production.
The use of mound soil in construction must account for variability in soil properties. Mound soil from different termite species and different geological settings will have different particle size distributions, clay mineralogy, and organic matter content. Testing mound soil for suitability before large-scale construction is essential to ensure structural performance.
Mound Detection and Monitoring
Termite mounds can be detected and monitored using a range of techniques, from visual inspection to advanced remote sensing. Visual inspection is the simplest method, relying on the distinctive shape and color of mounds against the surrounding landscape. However, visual inspection is time-consuming and limited to accessible areas.
Ground-penetrating radar, acoustic detection, and electrical resistivity imaging are physical sensing methods that enable non-invasive localization of subsurface anomalies [15]. These techniques are particularly useful for detecting termite activity in embankments and levees, where tunneling can create internal voids that lead to water leakage or structural failure [15]. Biological characteristic-based methods, including electronic noses, sniffer dogs, and UAV-based image analysis, detect volatile compounds and surface activity signs associated with termites [15].
UAV laser scanning provides a precise and scalable tool for termite mound detection and morphological characterization [19]. In a study from Litchfield National Park in Australia, UAV laser scanning detected 81 percent of mounds in high-resolution data and 72 percent in lower-resolution data, with accurate extraction of mound height and volume [19]. This technology allows rapid mapping of mound populations over relatively large areas with higher spatial detail than airborne or spaceborne remote sensing [19].
For property owners, mound detection near buildings is important for assessing termite risk. The presence of a mound near a house does not automatically mean the house is infested, but it indicates that termites are active in the area. Professional inspection is recommended to determine whether termites are entering the structure and to identify conditions that may attract termites, such as wood-to-soil contact, moisture problems, or mulch against the foundation.
Mound Ecology and Ecosystem Services
Termite mounds are ecosystem engineers that create habitat heterogeneity and influence ecosystem structure and function. In savannas, mound-building fungus-farming Macrotermitinae are key determinants of savanna structure and function [5]. Mounds create islands of fertility that support distinct plant communities, and they provide habitat for a range of invertebrates and small vertebrates.
The relationship between termites and large herbivores is complex. In a Kenyan savanna, experimental exclusion of large mammalian herbivores over 20 years showed that termite mound abundance and cover respond to herbivore-mediated changes in vegetation [8]. Termite mound abundance was positively associated with the presence of cattle but not with wild mesoherbivores or megaherbivores [8]. Herbaceous productivity and tree density, both affected by herbivore treatments, were positive predictors of termite mound abundance [8].
Ungulate grazing can also affect mound internal temperature. In a study of Macrotermes subhyalinus mounds, ungulates selectively fed on the eastern side of mounds, reducing vegetation cover and exposing that sector to the warming morning sun [5]. Soil sodium concentration was high on the eastern open mound sector, while plant nutrients accumulated on the western side, facilitating vegetation growth that shaded mounds from the hot afternoon sun [5]. When large herbivores were excluded, trees established on the eastern side and eventually covered the mounds completely, reducing internal mound temperature by 1.6 degrees and creating sub-optimal conditions for termite colonies [5].
Termites also contribute to greenhouse gas dynamics. Termites emit methane as they digest plant material, and global estimates of termite-derived methane are calculated using termite emission factors and estimated biomass [7]. However, this approach overlooks how the mound environment influences emissions to the atmosphere. In a study of three mound-building termite species in northern Australia, methane emissions increased with temperature and were highest in the wet-to-dry transition season [7]. Mound structure, bacterial methanotroph communities, and pmoA abundance had no effect on methane emissions in that study [7].
Termite Mound Near House: Risk Assessment
A termite mound near a house requires assessment to determine whether the colony poses a risk to the structure. The presence of a mound indicates an established termite colony in the area, but the risk depends on the termite species, the distance from the house, and the construction of the house.
Subterranean termites that build mounds are the primary concern for homeowners. These termites forage underground and can enter buildings through cracks in foundations, expansion joints, and utility penetrations. They build mud tubes on foundation walls to maintain moisture as they travel between the soil and the wood they consume. The mound itself is the colony center, but the foraging territory can extend 50 meters or more from the mound.
Wood-feeding termites such as Coptotermes species are particularly destructive. Coptotermes acinaciformis had the highest termite emission factors in a northern Australian study, and Coptotermes species are known for their ability to infest buildings [7]. These termites can cause significant structural damage before they are detected because they consume wood from the inside, leaving a thin outer shell.
Soil-feeding termites, in contrast, pose little direct risk to buildings because they consume soil organic matter instead of wood. Their mounds are common in tropical pastures and forests, and they improve soil fertility without threatening structures [11]. However, their presence indicates soil conditions that may also support wood-feeding species.
Professional inspection is recommended when a mound is found near a house. The inspector should identify the termite species, assess the distance from the mound to the structure, and check for conditions that facilitate termite entry. Treatment options include soil barriers, bait systems, and wood treatment, depending on the species and the extent of the problem. Regular inspection is important because termite colonies can expand and new colonies can establish.
Mound Management and Conservation
Termite mounds are valuable components of tropical and subtropical ecosystems, and their conservation should be considered in land management decisions. Mounds enhance soil fertility, support biodiversity, and contribute to ecosystem resilience [10]. Removing mounds for agriculture or development should be weighed against these ecological benefits.
In agricultural systems, mounds can be integrated into field management instead of removed. Mound soil can be spread on fields as a fertilizer, and mounds can be preserved as refuges for beneficial organisms. In pasture systems, mounds provide shade and forage for livestock and support plant diversity [11].
In embankment and levee management, termite activity is a serious concern because tunneling can create internal voids that compromise structural integrity [15]. Detection and monitoring are essential for early warning and rapid response. Integrated multi-sensor frameworks and artificial intelligence algorithms are emerging solutions to enhance detection accuracy and automation [15].
For termite species used as poultry feed, sustainable harvesting practices are important to maintain local populations. Farmers should avoid destroying entire mounds and should rotate harvesting sites to allow colonies to recover. Research on termite diversity and identification can support the sustainable use of termites as feed [13].

Practical Assessment of Mounds on Your Land
Assessing termite mounds on your land requires a systematic approach that identifies the termite species, evaluates the mound condition, and determines the risk to structures or crops. The following steps provide a practical workflow for land managers, farmers, and property owners.
First, identify the termite species if possible. Collect a few worker termites from the mound surface or from a broken section of the wall. Note the color, size, and shape of the workers and soldiers. Compare your observations with local identification guides or consult an extension service. Species identification matters because wood-feeding species pose a structural risk while soil-feeding species do not.
Second, measure the mound dimensions. Record the height, the longest and shortest diameters at the base, and the condition of the outer wall. A mound with an intact, hard outer wall is likely active. A mound with eroded surfaces, vegetation growing on it, or holes from predators may be abandoned or declining. Active mounds typically have fresh soil at the surface and visible termite activity at openings.
Third, assess the distance from the mound to any structures. Subterranean termites can forage 50 meters or more from the mound, so a mound within this range warrants inspection of the building foundation, crawl spaces, and any wood-to-soil contacts. Look for mud tubes on foundation walls, damaged wood, and termite swarmers inside the building.
Fourth, evaluate the soil and drainage conditions around the mound. Termites require moisture, so areas with poor drainage, leaking pipes, or excessive mulch can support termite activity. Correcting moisture problems reduces the attractiveness of the area to termites.
Fifth, decide on management action based on the assessment. If the mound is built by soil-feeding termites and is not near structures, no action is needed. If the mound is built by wood-feeding termites near a house, professional pest control is recommended. If the mound is in a crop field, consider using the mound soil as a fertility amendment instead of destroying the mound.
Records and Measurements for Mound Monitoring
Maintaining records of termite mound observations supports long-term monitoring and informed management decisions. The following measurements and records are useful for tracking mound populations and assessing changes over time.
Record the location of each mound using GPS coordinates or a map reference. Note the date of observation and the observer. Photograph the mound from a consistent angle to document changes in size and condition.
Measure mound height using a measuring pole or laser rangefinder. Measure the longest and shortest diameters at the base. Estimate mound volume using the formula for an ellipsoid or cone, depending on the mound shape. For accurate volume measurements, UAV laser scanning provides precise data [19].
Record the vegetation around the mound, including the dominant plant species and the percentage of ground cover. Vegetation affects mound temperature and termite colony health [5]. Note any signs of herbivore activity, such as grazing, trampling, or digging.
Record soil conditions, including soil type, drainage, and any recent disturbances such as plowing, burning, or construction. These factors influence termite activity and mound persistence.
Record termite activity by observing the mound surface for fresh soil, openings, and foraging trails. Note the presence of soldiers at the surface, which indicates colony defense activity. If possible, estimate colony size by observing the number of workers at foraging sites.
Review records annually to identify trends in mound abundance, size, and activity. Declines in mound numbers may indicate environmental stress, while increases may indicate favorable conditions or reduced predation.
Common Failure Patterns in Mound Management
Several common mistakes occur in termite mound management. Recognizing these patterns helps avoid ineffective actions and unintended consequences.
The first failure pattern is misidentifying the termite species and treating all mounds as structural threats. Soil-feeding termites improve soil fertility and pose no risk to buildings [11]. Destroying their mounds reduces soil quality and biodiversity without protecting structures. Correct species identification is the foundation of appropriate management.
The second failure pattern is ignoring the mound near a house until structural damage appears. Termite damage is often hidden inside walls and structural timbers, and by the time it is visible, the colony may have caused significant harm. Regular inspection of foundations, crawl spaces, and wood-to-soil contacts is essential when mounds are present.
The third failure pattern is relying on a single treatment without addressing the conditions that attract termites. Moisture problems, wood-to-soil contact, and excessive mulch create favorable conditions for termites regardless of treatment. Correcting these conditions is as important as applying termiticides or bait systems.
The fourth failure pattern is destroying mounds without considering their ecological value. Mounds support biodiversity, enhance soil fertility, and contribute to ecosystem resilience [10]. In agricultural landscapes, mound soil can be used as a fertility amendment instead of discarded [16].
The fifth failure pattern is failing to monitor after treatment. Termite colonies can recover, and new colonies can establish. Ongoing monitoring is necessary to detect reinfestation early and to adjust management strategies.
Limitations and Knowledge Gaps
Current understanding of termite mounds has several limitations that affect practical applications. Mound structure and function vary widely among species, and findings from one species or region may not apply to others. The morphological diversity of mounds ranges widely in size and shape, and the mechanisms controlling this diversity are not fully understood [4].
The relationship between mound structure and climate control is still not fully understood. Although there has been extensive interest in this topic, especially for designing energy-efficient buildings, it is still not clear how mound properties are controlled [6]. Interdisciplinary approaches combining X-ray tomography and flow field simulations are needed to deepen understanding of mound structure and its climate-regulating functions [6].
Methane emission estimates from termites are uncertain because they overlook how the mound environment influences emissions to the atmosphere [7]. Termite feeding habits, mound methanotrophs, and mound structure, as well as temperature and season, can influence net methane emission but remain unparameterized [7]. Improved estimates require accounting for these factors.
The effects of land-use change on termite mounds and their associated microbial communities are poorly understood. Forest conversion to plantations alters termite gut microbiomes, with effects varying across host species [14]. These changes may affect ecosystem functional resilience under anthropogenic disturbance [14].
Remote sensing methods for mound detection have trade-offs between area coverage and detection accuracy. High-resolution data provide more accurate estimates but cover less area, while lower-resolution data cover more area with reduced detectability [19]. Choosing the appropriate resolution requires balancing these trade-offs for specific monitoring objectives.
Safety and Regulatory Context
Termite mound management involves safety considerations for workers, property owners, and the environment. Termite control products are regulated in most jurisdictions, and their use must comply with label instructions and local regulations. Pesticide applications should be performed by licensed professionals where required.
When collecting mound soil for agricultural or construction use, workers should be aware of potential hazards. Mound soil may contain sharp particles, and digging into active mounds can disturb aggressive soldier termites. Protective gloves and eye protection are recommended. In areas with venomous snakes or other wildlife, caution is needed when working around mounds.
Termite mounds in embankments and levees pose a structural safety risk. Termite tunneling can create internal voids, water leakage, or even dam failure [15]. Detection and monitoring are essential for early warning and rapid response [15]. Engineers and maintenance personnel should follow established protocols for termite detection and management in critical infrastructure.
The use of termites as poultry feed is a traditional practice in some regions, but food safety considerations apply. Termites should be collected from areas free of pesticide contamination. In Burkina Faso, poultry farmers use termites as feed, and research supports the promotion of this practice [13]. However, the nutritional quality and safety of termites as feed depend on the species and the collection environment.
Professional Escalation Criteria
Certain situations require professional assessment and intervention. Property owners and land managers should seek professional help when they observe any of the following conditions.
Contact a licensed pest control professional if you find a termite mound within 50 meters of a house or other wooden structure. The professional can identify the species, assess the risk, and recommend treatment options. Do not attempt to treat a mound yourself without proper training and equipment.
Contact a structural engineer or embankment specialist if termite activity is detected in a dam, levee, or other critical infrastructure. Termite tunneling can compromise structural integrity, and professional assessment is essential to prevent failure [15].
Contact an agricultural extension service or soil scientist if you plan to use mound soil as a fertility amendment on a large scale. Soil testing can determine the nutrient content of the mound soil and guide application rates to match crop demand [16].
Contact a wildlife or conservation authority if you are managing land with significant termite mound populations. Mounds provide important ecosystem services, and conservation planning should consider their value [10].
Contact a termite researcher or university specialist if you observe unusual mound morphology, rapid mound decline, or other phenomena that suggest environmental stress or emerging threats. Research on mound ecology and climate control is ongoing, and observations from the field can contribute to scientific understanding [4][6].
Frequently Asked Questions
How tall can termite mounds get?
Termite mounds range from small domes under 30 centimeters to large structures exceeding 3 meters in height. The largest mounds are built by fungus-farming Macrotermes species in African savannas, which can reach 4 meters or more. Mound height depends on species, colony age, soil type, and environmental conditions. Compass termites in Australia build wedge-shaped mounds up to 3 to 4 meters tall but only 1 to 2 meters wide [22].
What are termite mounds made of?
Termite mounds are made of soil particles transported by worker termites and cemented with saliva and fecal material. The composition reflects the local soil type and the termite species. Mound soil typically has higher organic carbon, available phosphorus, and exchangeable cations than surrounding topsoil [11]. The outer wall is denser and harder than the inner core, which contains the nest chambers and galleries.
Do termite mounds indicate a house infestation?
A termite mound near a house indicates that termites are active in the area, but it does not automatically mean the house is infested. The risk depends on the termite species and the distance from the mound to the structure. Wood-feeding subterranean termites can forage 50 meters or more from the mound and may enter buildings through cracks and utility penetrations. Professional inspection is recommended to assess the risk.
Can termite mound soil be used as fertilizer?
Termite mound soil is fertile and can be used as a soil amendment. It has higher organic carbon, available nitrogen, phosphorus, and potassium than surrounding soils [16]. A potting medium with mound soil, sand, and farmyard manure in a 1:1:2 ratio showed the best results for nutrient content and enzyme activity [16]. Soil testing is recommended before large-scale application to match nutrient supply to crop demand.
Are termites used as poultry feed?
Termites are used as poultry feed in several regions of Africa and Asia.
