Current Situation in Nevada
Nevada is the driest state in the nation, which naturally limits tick activity. However, the tick forecast for Nevada warns that "low risk" does not mean "no risk." The Rocky Mountain Wood Tick is found in the mountain ranges (like the Rubies and Sierra Nevada) and along river corridors. A unique risk in Nevada comes from soft ticks (*Ornithodoros*) found in rodent burrows and rustic cabins, which can transmit Relapsing Fever.

Where Ticks Hide in Nevada
Riparian zones (Truckee, Carson, Humboldt rivers) are the primary habitat for hard ticks. Mountain brush and pinyon-juniper woodlands also support populations. Soft ticks are found in caves, mines, and old cabins, feeding quickly at night. Lake Tahoe and the Spring Mountains (near Las Vegas) are recreational areas with tick presence.
Seasonal Activity Pattern
Spring (April-June) is the main season for hard ticks. Soft ticks can be active year-round if they are in a sheltered environment (like a cabin). The extreme heat of summer suppresses outdoor tick activity.

Local Vector Analysis
Understanding which ticks are active in Nevada helps you identify threats and take appropriate precautions.
Rocky Mountain Wood Tick
Dermacentor andersoni
Appearance: Brown with gray/white mottling, similar to dog tick but found at higher elevations.
Peak Season: March-July
Habitat: Shrublands, lightly wooded areas, and grasslands at 4,000 to 10,500 feet elevation.
Diseases: Rocky Mountain Spotted Fever, Colorado Tick Fever, Tularemia, Tick Paralysis
Note: Saliva contains neurotoxin that can cause Tick Paralysis (reversible after removal).
American Dog Tick
Dermacentor variabilis
Appearance: Brown with white/grey mottling. Ornate white patterns on shield.
Peak Season: Spring and Summer
Habitat: Grassy fields, walkways, and trails. More tolerant of dry conditions than Deer Ticks.
Diseases: Rocky Mountain Spotted Fever, Tularemia
Soft Tick (O. hermsii)
Ornithodoros hermsii
Appearance: Soft-bodied, leathery texture, no hard shield. Looks like a raisin. 5-8mm.
Peak Season: Active in mountain cabins year-round
Habitat: Rustic cabins, rodent burrows in coniferous forests at 900-2,000m elevation.
Diseases: Tick-Borne Relapsing Fever (TBRF)
Note: 🌙 Feeds at night for 15-30 minutes. Painless bite. Found in mountain cabins with rodent infestations.
Lyme Disease
Vector: Deer tick (Ixodes scapularis)
Lyme Disease
Lyme disease is a bacterial infection transmitted by deer ticks. If caught early, it's highly treatable with antibiotics. Left untreated, it can cause serious complications affecting joints, heart, and nervous system.
Early Warning Signs
- Erythema migrans (EM) rash - appears in 70-80% of cases
- Bullseye rash (circular red rash with clear center)
- Rash appears 3-30 days after bite
- Fever and chills
Progression & Symptoms
- Severe headaches and neck stiffness
- Facial palsy (loss of muscle tone on one or both sides of face)
- Arthritis with severe joint pain, especially knees
Prevention Strategies
The best way to avoid tick-borne diseases is to prevent tick bites in the first place. These strategies work together to create multiple layers of protection.
Permethrin-Treated Clothing
Permethrin is an insecticide that kills ticks on contact. When applied to clothing, it remains effective through multiple washes.
Daily Tick Checks
Since disease transmission typically requires 24-48 hours of attachment, finding and removing ticks quickly dramatically reduces infection risk.
Landscaping Defense
Creating a tick-hostile environment in your yard reduces the chance ticks will be waiting when you step outside.
Shower Within 2 Hours
Showering after outdoor activity gives you a chance to wash off ticks before they bite.
Tick Bite Protocol
Acting quickly and correctly is your best defense against infection.Follow these 6 critical steps.
Don't Panic
Most tick bites do not transmit disease, especially if removed quickly.
- Infection rates vary by region (20-50%)
- Transmission usually takes 24-48 hours
- Stay calm and use proper technique
Gather Tools
Use fine-tipped tweezers. Avoid fingers or chemicals.
- Fine-tipped tweezers are best
- Rubbing alcohol for cleaning
- Small container to save the tick
Grasp & Pull
Grasp close to skin and pull upward with steady pressure.
- Grab mouthparts near skin (not body)
- Pull straight up—don't twist
- Maintain steady, even pressure
Clean Area
Disinfect the bite site and your hands thoroughly.
- Wash with soap and water
- Apply rubbing alcohol
- Wash hands well
Save Tick
Keep the tick in a sealed container for potential testing.
- Seal in bag or container
- Label with date and location
- Bring to doctor if symptoms appear
Monitor (30 Days)
Watch for rash or flu-like symptoms for a month.
- Check for expanding rash daily
- Watch for fever or fatigue
- Seek care if you feel unwell
