«Understanding Bed Bugs»
«Physical Characteristics of Adult Bed Bugs»
«Size and Shape»
Bedbugs are small, oval insects measuring 4–5 mm in length and about 2 mm in width when unfed. Their bodies are flattened dorsoventrally, allowing them to hide in narrow crevices. After a blood meal, they swell to roughly 6–7 mm and become more rounded, though the overall silhouette remains broadly oval.
Ticks exhibit a broader size range that depends on species and life stage. Unfed nymphs are typically 1–2 mm long, while unfed adult females of common species such as the American dog tick reach 3–5 mm. After engorgement, females can expand to 10–12 mm or more, becoming markedly spherical. The dorsal surface is shield‑shaped in hard ticks (Ixodidae) and more rounded in soft ticks (Argasidae). Legs extend laterally from the body, giving the tick a distinctive, eight‑legged appearance that contrasts with the six‑legged profile of bedbugs.
«Coloration»
Bedbugs display a uniform, flat body that ranges from dark reddish‑brown to mahogany. Their color deepens after a blood meal, turning a brighter, almost brick‑red hue as they swell. The abdomen may appear slightly translucent when engorged, revealing the ingested blood. Legs and antennae are lighter, typically tan to pale brown, contrasting with the darker thorax.
Ticks exhibit a broader spectrum of coloration that varies by species, developmental stage, and engorgement level:
- Larvae (seed ticks): translucent or pale cream, almost invisible on light surfaces.
- Nymphs: reddish‑brown to olive, often with faint scutum markings.
- Adults: species‑specific colors; for example, the American dog tick (Dermacentor variabilis) is brown with white or silver markings, while the blacklegged tick (Ixodes scapularis) is dark brown to black. Engorged adults become markedly swollen and may appear grayish‑blue or deep purple, reflecting the expanded blood volume.
Both insects rely on coloration for camouflage: bedbugs blend with mattress fabrics and furniture, whereas ticks match the host’s skin or vegetation, enhancing their ability to remain undetected.
«Body Segments»
Bedbugs are insects with a three‑part body plan. The head bears a pair of compound eyes, short antennae, and a beak‑like proboscis used for blood feeding. The thorax consists of three fused segments, each supporting a single pair of legs and a pair of wings that are reduced to tiny, non‑functional structures. The abdomen is composed of eleven visible dorsal plates (tergites) and contains the digestive tract, reproductive organs, and a series of spiracles for respiration.
Ticks belong to the arachnid class and display a two‑region body organization. The anterior capitulum includes the mouthparts: chelicerae, palps, and a barbed hypostome for attachment to hosts. The posterior idiosoma comprises the main body mass, divided into a series of dorsal shields (scutum in hard ticks or festoons in soft ticks) and a ventral plate. Eight legs emerge from the idiosoma, each attached to a distinct segment that allows flexible movement. The idiosoma also houses the digestive system, reproductive structures, and respiratory openings (spiracular plates).
«Antennae and Legs»
Bedbugs possess a pair of short, slender antennae located near the head, each segment visible as a series of tiny, bead‑like rings. Their legs are six in total, arranged in three pairs along the thorax. Each leg ends in a claw and a small pad that facilitates rapid movement across fabrics. The legs are relatively thin, with a pale, translucent coloration that matches the insect’s overall reddish‑brown body.
Ticks feature elongated, segmented mouthparts rather than true antennae; the sensory structures resemble short, hair‑like projections on the front of the idiosoma. Their legs are eight in number, grouped in four pairs, and are noticeably longer than those of bedbugs. Each leg is jointed, bearing a pair of claws and a specialized hook called a “palp” used for attachment to hosts. The legs display a dark brown to black hue, contrasting with the lighter scutum that covers the dorsal surface.
- Bedbug antennae: short, segmented, bead‑like, near the head.
- Bedbug legs: six, thin, translucent, clawed, pad‑ended.
- Tick sensory structures: hair‑like projections, not true antennae.
- Tick legs: eight, long, jointed, dark, with claws and palps.
«Identifying Bed Bug Nymphs (Immature Stages)»
«Appearance of Hatchlings»
Bedbug hatchlings, known as first‑instar nymphs, are markedly smaller than mature insects and lack fully developed wings. Their bodies measure roughly 1 mm in length, appear translucent to light brown, and display a flattened dorsal surface. The abdomen shows faint reddish‑brown spotting, and the three‑segmented antennae are proportionally longer than in later stages. Legs are slender, each ending in tiny claws that enable brief crawling on fabrics.
- Length: ~1 mm
- Color: translucent to pale brown, faint abdominal spots
- Body shape: flattened, elongated
- Antennae: three segments, relatively long
- Legs: thin, ending in minute claws
Tick hatchlings, termed larvae or “seed ticks,” emerge from eggs at about 0.5 mm in diameter. Their bodies are spherical, covered with a fine, silvery‑gray scutum that gives a glossy appearance. Each larva possesses six legs, in contrast to the eight legs of later stages, and lacks visible mouthparts for blood feeding. The coloration is uniformly pale, becoming darker only after the first blood meal.
- Size: ~0.5 mm diameter
- Color: silvery‑gray, glossy scutum
- Body shape: spherical, smooth
- Legs: six, short, not adapted for attachment
- Mouthparts: absent or vestigial
Comparatively, bedbug nymphs are elongated and lightly pigmented, while tick larvae are compact and uniformly silvery. Both stages are microscopic, requiring magnification for reliable identification, and their limited mobility restricts immediate host contact until later developmental phases.
«Changes During Molting»
Molting, or ecdysis, is the process by which arthropods shed their exoskeleton to grow. During each molt, the cuticle thins, expands, and hardens, producing noticeable alterations in size, coloration, and body segmentation.
In bedbugs, the transition from first‑instar nymph to adult involves three molts. After each shedding event the insect increases in length by roughly 30 % and its oval shape becomes more pronounced. The initially pale, translucent cuticle darkens to the characteristic reddish‑brown hue, and the wing‑case (hemelytron) becomes more defined. Antennae lengthen proportionally, and the dorsal abdominal plates acquire clearer punctate markings.
Ticks undergo four developmental stages—egg, larva, nymph, and adult—each separated by a molt. The larval stage presents a tiny, reddish‑brown sphere lacking visible legs. Following the first molt, the nymph displays eight legs, a more elongated body, and a slightly darker coloration. The second molt yields the adult, which attains a robust, oval silhouette, a scutum (shield) on the dorsal surface, and distinct segmentation. Color deepens to a darker brown or black, and the mouthparts become more prominent.
Key visual changes during molting:
- Increase in overall length and girth
- Darkening of cuticle pigmentation
- Development of distinct body structures (e.g., scutum in ticks, hemelytron in bedbugs)
- Lengthening of antennae and legs
- Emergence of species‑specific markings
These transformations provide reliable criteria for identifying the developmental stage of each parasite in field and laboratory observations.
«Signs of Bed Bug Infestation Beyond the Bugs Themselves»
«Fecal Spots»
Fecal spots serve as reliable visual indicators when assessing the presence of common ectoparasites. The deposits consist of digested blood and excreted waste, leaving characteristic stains on surfaces where the insects feed or rest.
Bedbug fecal spots appear as tiny, dark‑brown to black specks roughly 0.2–0.5 mm in diameter. They often form linear trails or clustered dots on mattress seams, pillowcases, and nearby walls. The spots are matte, lacking a glossy sheen, and may be surrounded by a faint reddish halo caused by residual blood.
Tick fecal spots are larger, typically 0.5–1 mm, and range from dark brown to reddish‑orange. They commonly occur on the undersides of animal hides, in bedding, or on vegetation where ticks detach after feeding. The deposits are often more irregular in shape, sometimes resembling small smears rather than discrete dots.
Detection relies on close visual inspection under adequate lighting. Distinguishing features include:
- Size: bedbug spots are smaller than tick spots.
- Color: bedbug deposits are uniformly dark; tick deposits may show reddish tones.
- Distribution: bedbug spots cluster on fabric seams; tick spots appear on animal fur or vegetation.
Recognizing fecal spots enables early intervention, preventing infestation escalation and reducing health risks associated with these parasites.
«Shed Skins»
Shed skins, or exuviae, are the primary evidence of recent activity by bedbugs and ticks and provide a reliable means of confirming their presence without needing live specimens.
When a bedbug molts, it leaves a translucent, parchment‑like shell about 4–5 mm long. The exuvia retains the insect’s characteristic oval shape and the distinct darkened wing pads that will later become the fully developed wings. The shell’s edges are smooth, and the coloration ranges from light brown to amber, matching the nymph’s cuticle before feeding.
Tick exuviae differ in size and texture. A tick’s cast skin measures 2–6 mm, depending on the species and developmental stage. The shed cuticle is rigid, often showing the scutum—a hardened plate on the dorsal surface—and the segmentation of the legs. The exuvia’s coloration is typically dark brown to black, with a glossy surface that contrasts with the softer, more matte appearance of a bedbug shell.
Key identification points for shed skins:
- Size: bedbug exuviae ≈ 4–5 mm; tick exuviae 2–6 mm, variable by stage.
- Shape: bedbug shells oval, smooth edges; tick shells elongated, with visible scutum and leg segments.
- Texture: bedbug exuviae parchment‑like, flexible; tick exuviae rigid, glossy.
- Color: bedbug shells light brown to amber; tick shells dark brown to black.
Collecting shed skins from mattress seams, furniture crevices, or pet bedding allows inspectors to differentiate between the two pests quickly and to target control measures appropriately.
«Bite Marks (General Appearance)»
Bite marks produced by bedbugs and ticks differ in size, shape, and surrounding skin reaction, allowing clinicians and pest‑control professionals to identify the culprit.
-
Bedbug bites are typically 2–5 mm, red, and appear as clustered groups or linear “break‑fast‑bar” patterns. The central puncture may be slightly raised, and the surrounding area often exhibits mild swelling that peaks within a few hours. Lesions are usually pruritic and may develop a central dark spot if the insect’s saliva triggers a localized hemorrhage.
-
Tick bites range from 3 mm to over 1 cm, reflecting the larger mouthparts of the arachnid. The bite site is often a single, round, erythematous papule with a clear or slightly raised margin. In many cases, a small central punctum, known as the “tick bite scar,” remains visible after the tick detaches. Some species, such as Ixodes scapularis, can produce a bull’s‑eye rash (erythema migrans) that expands outward from the initial puncture.
Key distinguishing characteristics:
- Arrangement: bedbug bites occur in groups; tick bites are solitary.
- Size: tick bites are generally larger, sometimes exceeding 5 mm.
- Central punctum: more evident in tick bites; often absent or faint in bedbug lesions.
- Temporal pattern: bedbug reactions develop rapidly (within minutes to hours); tick reactions may be delayed, with erythema appearing 24–48 hours after attachment.
Recognizing these patterns supports accurate diagnosis and informs appropriate treatment and eradication measures.
«Exploring Ticks»
«General Tick Anatomy»
«Body Shape and Size»
Bedbugs are small, flat‑ovoid insects measuring approximately 4–5 mm in length when unfed and expanding to about 6–7 mm after a blood meal. Their bodies are dorsally convex, with a distinct, shield‑like thorax and abdomen that appear almost seamless. Antennae consist of five segments, and each side bears three pairs of short, curved legs. Color varies from pale yellow to reddish‑brown after feeding.
Ticks are arachnids ranging from 2 mm in the unfed larval stage to 10 mm or more in adult females when engorged. Their bodies consist of two main sections: the anterior capitulum, housing the mouthparts, and the posterior idiosoma, which expands dramatically during blood ingestion. Legs are eight in number, long enough to grasp host fur or skin, and the dorsal surface is covered with a hard or soft scutum depending on species.
- Bedbug size: 4–5 mm (unfed) → 6–7 mm (fed)
- Tick size: 2 mm (larva) → up to 10 mm+ (engorged adult)
- Body shape: bedbug – flat, oval; tick – rounded, expandable idiosoma
- Leg count: bedbug – six; tick – eight
These dimensions and structural features enable both parasites to navigate host environments and remain concealed during feeding.
«Color Variations»
Bedbugs and ticks can be distinguished by a range of coloration that changes with age, feeding status, and species. Recognizing these variations aids accurate identification and effective control measures.
-
Bedbugs (Cimex spp.)
- Unfed adults: reddish‑brown, often described as “mahogany” or “cocoa” hue.
- After a blood meal: abdomen expands, color deepens to a darker, almost black shade.
- Nymphs: lighter tan or straw‑colored; each molt adds a subtle increase in pigmentation.
- Eggs: translucent white, rarely visible without magnification.
-
Ticks (Ixodida)
- Unengorged adults: shades range from light brown to dark brown, sometimes exhibiting a grayish or olive tint depending on species.
- Engorged females: abdomen swells, color shifts to a pale, almost ivory or reddish‑orange tone as they fill with blood.
- Nymphs and larvae: typically lighter, often golden‑brown or pale yellow, with distinct scutal patterns that may appear darker.
- Some species, such as the American dog tick (Dermacentor variabilis), display distinctive white or orange markings on the dorsal surface.
Understanding these color patterns, together with size and body shape, provides a reliable basis for distinguishing bedbugs from ticks in field inspections.
«Legs and Mouthparts (Capitulum)»
Bedbugs (Cimex lectularius) possess six short, robust legs attached to the thorax. Each leg ends in a pair of claws and a set of sensory hairs that detect host movement and temperature. The legs are positioned laterally, giving the insect a flattened profile that aids in navigating tight crevices.
Ticks (Ixodida) display eight legs, characteristic of arachnids. The first pair is longer than the remaining three pairs, enabling the organism to grasp hosts effectively. Legs are segmented into coxae, trochanters, femora, patellae, tibiae, and tarsal claws, each segment bearing sensory organs for detecting heat, carbon dioxide, and vibrations.
Both taxa share a specialized feeding apparatus known as the capitulum. In bedbugs, the capitulum consists of a beak‑like rostrum formed by a pair of elongated stylets enclosed within a sheath. The stylets penetrate the skin, inject saliva containing anticoagulants, and draw blood through a narrow canal.
Ticks feature a capitulum with a hypostome, chelicerae, and palps. The hypostome is a barbed, serrated structure that anchors the tick to the host’s flesh. Chelicerae assist in cutting the skin, while palps serve sensory functions, guiding the hypostome during insertion. The mouthparts are concealed beneath a dorsal scutum when not feeding, then extend outward during attachment.
Key comparative points:
- Leg count: six in bedbugs, eight in ticks.
- Leg function: bedbug legs aid in rapid crawling; tick legs provide grip and sensory detection for prolonged attachment.
- Capitulum design: bedbug rostrum is slender and needle‑like; tick capitulum includes a barbed hypostome and auxiliary chelicerae.
These morphological differences determine how each parasite locates, attaches to, and feeds from its host.
«Common Tick Species and Their Appearance»
«Deer Ticks (Blacklegged Ticks)»
Deer ticks, scientifically known as Ixodes scapularis, are small arachnids measuring 2–3 mm when unfed. Their bodies are oval, resembling a flattened, elongated seed. The dorsal surface is dark brown to reddish‑brown, while the ventral side is lighter, often grayish. Legs are long relative to body size, extending outward in a characteristic “outstretched” posture; each leg bears a small, darkened segment near the tip called a scutum in males and a partial scutum in females.
Key visual traits include:
- Size: 2–3 mm (unfed), expanding to 5–10 mm after a blood meal.
- Color: Dark brown to reddish‑brown dorsally; lighter ventrally.
- Shape: Oval, flattened body with a smooth, non‑hairy surface.
- Legs: Eight long legs, each ending in a small claw; males display a full scutum covering the entire back, whereas females have a partial scutum leaving most of the abdomen uncovered.
- Mouthparts: Short, forward‑projecting chelicerae used for piercing skin.
In contrast, common bedbugs (Cimex lectularius) are larger, 4–5 mm long, with a flattened, oval body that is reddish‑brown after feeding and light brown when unfed. They possess six legs, not eight, and lack the distinctive scutum seen in ticks. Bedbugs also have a more pronounced, bean‑shaped silhouette and visible antennae, absent in ticks.
Understanding these morphological differences aids accurate identification and appropriate control measures.
«American Dog Ticks»
American Dog Ticks (Dermacentor variabilis) are hard-bodied arachnids measuring 3–5 mm when unfed and expanding to 10 mm after a blood meal. The dorsal surface is brown to reddish‑brown, marked by a distinctive white or ivory scutum that forms a shield on the back of the adult female and a partial shield on the male. The scutum bears a pattern of pale, irregular patches and a dark central spot on the female. Legs are eight, segmented, and relatively long, giving the tick a sturdy, “spider‑like” silhouette.
Key visual traits of American Dog Ticks:
- Oval, compact body; not flat like bedbugs.
- Dark brown to reddish coloration with a lighter scutum.
- Presence of eyes on the sides of the head (two pairs in adults).
- Whitish, crescent‑shaped band on the dorsal surface of the female.
- Engorged females become markedly swollen, turning grayish‑white.
In contrast, bedbugs (Cimex lectularius) are flat, wingless insects about 4–5 mm long, with a reddish‑brown, oval shape and no scutum or visible eyes. Their bodies remain relatively thin after feeding, unlike the dramatic expansion seen in engorged ticks. These morphological differences enable reliable identification in field or clinical settings.
«Lone Star Ticks»
Lone Star ticks (Amblyomma americanum) are medium‑sized arachnids, typically 3–5 mm long when unfed and expanding to 10 mm after a blood meal. The dorsal shield (scutum) is dark brown to black, often with a pale, star‑shaped white spot near the anterior edge of the female’s scutum—hence the common name. Males lack the distinct spot but display a broader, more uniformly dark scutum. Legs are long, slender, and banded with alternating light and dark segments, giving a striped appearance. The ventral side is lighter, usually pale orange or yellow, and the mouthparts (chelicerae) are visible as small, dark projections at the front.
Key visual characteristics:
- Dark brown to black scutum with a single white “lone star” on females
- Long, banded legs with alternating light and dark rings
- Oval body shape, slightly flattened dorsally
- Engorged females become noticeably swollen and pale‑colored
These traits differentiate Lone Star ticks from other tick species and from common bedbugs, which are small, flat, reddish‑brown insects lacking a scutum and exhibiting a more oval, wingless body shape.
«Brown Dog Ticks»
Brown dog ticks (Rhipicephalus sanguineus) are small, flat arachnids ranging from 2 mm to 5 mm in length when unfed. Their bodies are oval and leathery, covered with fine, short hairs that give a brown‑gray appearance. The dorsal shield (scutum) is darker, often appearing as a distinct, slightly raised band. Legs extend laterally, each ending in a small claw that aids attachment to hosts.
In the engorged state, after feeding on blood, the tick expands dramatically, reaching up to 10 mm in length and becoming noticeably swollen and lighter in color. The abdomen stretches, and the overall shape changes from a compact oval to a more rounded, balloon‑like form.
Larval brown dog ticks measure about 0.5 mm, are translucent, and lack the pronounced scutum seen in adults. Nymphs are slightly larger (1–2 mm), retain a pale brown hue, and possess a less developed scutum. All stages exhibit a hard, protective cuticle that resists desiccation.
Key visual identifiers:
- Oval, flat body with a darker dorsal shield.
- Uniform brown‑gray coloration in unfed adults.
- Significant size increase and color lightening after engorgement.
- Short, sturdy legs ending in claws.
«Distinguishing Between Engorged and Unengorged Ticks»
«Appearance When Unfed»
Unfed bedbugs are flat, oval‑shaped insects about 4–5 mm long. Their bodies are reddish‑brown, becoming paler after feeding. The dorsal surface is smooth, lacking visible hairs, while the ventral side shows a pair of small, curved wing‑like extensions (the hemelytra). Antennae consist of six segments, each slender and dark. Legs are thin, ending in tiny claws that allow rapid movement across fabric.
Unfed ticks appear as small, rounded arachnids ranging from 2 mm in larvae to 5 mm in nymphs. Their exoskeleton is hard and brown to reddish‑brown, often displaying a patterned scutum (a shield on the dorsal side) in species such as the deer tick. Eight legs are clearly visible, each bearing a pair of sensory organs (palps) near the mouthparts. The body is divided into a capitulum (head) and idiosoma (body), with the latter expanding dramatically after a blood meal.
Key visual differences when both are unfed:
- Shape: bedbug – flat, oval; tick – rounded, shield‑like.
- Size range: bedbug – 4–5 mm; tick – 2–5 mm (larvae to nymph).
- Body covering: bedbug – smooth, hairless; tick – hardened scutum, often patterned.
- Legs: bedbug – six legs, short; tick – eight legs, longer relative to body.
- Mouthparts: bedbug – elongated beak (proboscis) hidden beneath head; tick – visible capitulum with chelicerae and palps.
«Appearance After Feeding»
After a blood meal, a bedbug’s body expands noticeably. The abdomen becomes rounded and swollen, often increasing in size by up to 2‑3 mm. The cuticle darkens to a reddish‑brown hue, especially along the edges of the abdomen, while the head and thorax retain their lighter, tan coloration. The insect’s legs may appear slightly more splayed as the abdomen pushes outward, and the overall silhouette changes from a flat, oval shape to a more dome‑shaped profile.
A fed tick exhibits a distinct transformation. The engorged specimen’s body length can increase severalfold, and the scutum (the hard shield on the dorsal surface) remains unchanged in size, creating a striking contrast between the rigid shield and the stretched, balloon‑like posterior. The coloration shifts to a deep, almost black shade, with the cuticle becoming glossy and taut. The legs spread outward to support the enlarged abdomen, and the tick’s overall outline becomes markedly convex rather than the flat, oval form observed before feeding.
«Key Differences Between Bed Bugs and Ticks»
«Habitat and Preferred Hiding Spots»
Bedbugs inhabit human dwellings, thriving in environments where people sleep or rest. They are most frequently encountered in:
- Mattress seams, box‑spring folds, and bed frames
- Headboards, nightstands, and furniture crevices
- Wall baseboards and electrical outlet covers
- Luggage, backpacks, and personal clothing left unattended
These insects prefer dark, protected zones close to a blood source, allowing them to feed without detection. Their flat, oval bodies enable them to squeeze into cracks no wider than a few millimeters.
Ticks occupy outdoor habitats but can also be found in indoor settings where hosts are present. Their typical locations include:
- Grassy fields, shrubs, and leaf litter where they wait for passing animals
- Forest understory and woodland edges, especially in humid microclimates
- Tall grasses and low vegetation in parks, gardens, and residential yards
- Pet bedding, carpets, and furniture in homes with infested animals
Ticks attach to hosts during the questing stage, positioning themselves on vegetation at shoulder height to latch onto passing mammals or birds. Their hardened exoskeleton protects them while they remain motionless for extended periods, awaiting a suitable blood meal.
«Feeding Behavior and Duration»
Bedbugs and ticks differ markedly in how they obtain blood and how long each feeding episode lasts.
Bedbugs locate a host primarily by detecting carbon dioxide and body heat. They emerge from hiding places at night, crawl onto exposed skin, and insert a needle‑like mouthpart to pierce the epidermis. The feeding process typically lasts five to ten minutes, after which the insect withdraws and drops off. Engorgement results in a swollen, reddish abdomen, but the insect does not remain attached to the host for an extended period. Multiple feedings are required throughout the insect’s life cycle, with each meal providing enough protein to support development and reproduction.
Ticks attach by inserting their barbed hypostome into the skin, anchoring themselves securely. Feeding begins with a brief attachment phase of a few hours, followed by a slow, continuous intake of blood that can extend from three days to more than two weeks, depending on species and life stage. During this period the tick’s body expands dramatically, becoming markedly distended. Saliva containing anticoagulants and immunomodulatory compounds is secreted throughout the feeding interval, facilitating prolonged attachment and pathogen transmission.
Feeding duration comparison
- Bedbugs: 5–10 minutes per meal; multiple short meals over lifespan.
- Ticks: 3 days to >14 days per attachment; single prolonged meal per life stage.
Understanding these distinct feeding behaviors clarifies why visual identification alone does not reveal the full risk profile of each parasite.
«Impact on Hosts»
Bedbugs are small, flat, reddish‑brown insects about 4–5 mm long, while ticks are arachnids ranging from 2 mm to over 10 mm, with a hardened, oval body and distinct scutum. Both species attach to warm‑blooded hosts to obtain blood meals, a behavior that directly influences host health.
- Dermatological effects: Bites produce itchy, red welts that may develop into secondary bacterial infections if scratched.
- Allergic responses: Some individuals experience pronounced swelling, hives, or systemic allergic reactions.
- Psychological impact: Persistent infestations generate anxiety, sleep disturbance, and reduced quality of life.
- Pathogen transmission: Ticks are proven vectors for Lyme disease, Rocky Mountain spotted fever, and other bacterial or viral agents; bedbugs can carry, though rarely transmit, pathogens such as hepatitis B and C.
In livestock and companion animals, the same mechanisms cause weight loss, anemia, and increased susceptibility to disease, leading to economic losses in agricultural settings and additional veterinary care requirements.
