Deer Tick — Identification Guide

• Deer tick (Ixodes scapularis) — primary vector of Lyme disease and anaplasmosis. Small, reddish-brown legs, dark body. Peak nymph activity in spring/early summer.
• American dog tick (Dermacentor variabilis) — larger, brown with light patterned markings. Main NC vector of Rocky Mountain spotted fever.
• Lone star tick (Amblyomma americanum) — reddish-brown with a single white spot on the female's back. Vector of ehrlichiosis, STARI, and — notoriously — alpha-gal syndrome (a red-meat allergy triggered by tick saliva).
• Brown dog tick (Rhipicephalus sanguineus) — reddish-brown, primarily a dog-associated indoor tick, capable of establishing indoor populations.

Correct identification matters because disease risk varies significantly by species. Save any tick removed from a person or pet in a sealed bag for potential identification and testing.

North Carolina reports several thousand tick-borne disease cases per year across all species. The most consequential for Triangle residents:

• Lyme disease — from deer tick bites. Early rash (often but not always a bullseye), fever, fatigue; if untreated, joint, cardiac, and neurological complications.
• Rocky Mountain spotted fever — from American dog tick bites. Fever, rash, headache; can be severe if not treated early.
• Ehrlichiosis — from lone star tick bites. Fever, chills, muscle aches, low platelets.
• Alpha-gal syndrome — a delayed red-meat allergy triggered by lone star tick saliva. Once acquired, can be lifelong.

Prompt tick removal (within 24 hours) dramatically reduces disease transmission risk. Any fever or rash within a few weeks of a tick bite warrants medical evaluation.

Ticks do not fly or jump — they climb up onto low vegetation and wait for a host to brush past (a behavior called questing). In the Triangle, high-risk tick habitat includes:

• Wooded lot edges and yard-to-forest transitions.
• Tall grass, ground cover, ivy, and leaf litter along fence lines.
• Deer trails through neighborhood green space.
• Around bird feeders (small mammals visiting the feeders bring ticks).
• Wooded parts of Duke Forest, Umstead, Eno River, and any Triangle property backing onto natural areas.

Deer are the primary reproductive host, and the growing suburban deer population in the Triangle has driven a corresponding increase in tick pressure over the past decade.

• Ticks found on pets after outdoor time — often the earliest warning that yard pressure is high.
• Ticks attached to family members after yard time, gardening, or walks.
• Deer regularly visible in the yard — a strong indicator ticks are being deposited.
• Rodent activity near the perimeter — mice and chipmunks are important intermediate hosts.

If you are pulling multiple ticks off pets or family in a single season, professional outdoor tick control is worth considering.

Castle’s flea and tick yard treatment targets the wooded edges, leaf litter, tall grass and pet resting areas where ticks wait for a host. Products are EPA-registered and applied according to label directions, and we will tell you how long to keep people and pets off treated areas when the label requires it. Yard treatment works best alongside veterinary prevention for pets and the CDC’s tick-bite prevention advice.

• Use EPA-registered repellents (DEET, picaridin, permethrin-treated clothing) when in wooded areas.
• Tuck pants into socks in tick-heavy areas.
• Do a tick check after every outdoor session — armpits, groin, scalp, behind ears, waistline. Nymphs are poppy-seed sized.
• Shower within two hours of coming inside — this dislodges unattached ticks.
• Toss outdoor clothing directly into the dryer on high heat for ten minutes before washing — kills any ticks on fabric.
• Keep pets on year-round tick preventatives from your vet.
• Maintain the yard: mow regularly, remove leaf litter, keep ground cover away from active zones, consider a three-foot mulch or gravel border along woodline.
• If a tick is attached, remove promptly with fine-tipped tweezers, straight upward, without twisting. Save the tick in a sealed bag.
