A tiny tick bite can trigger Lyme disease, Rocky Mountain spotted fever, or dozens of other potentially fatal illnesses. These microscopic arachnids carry more diseases than any other vector except mosquitoes, and wilderness travelers are prime targets. Understanding tick behavior, proper removal techniques, and disease recognition can prevent months of debilitating illness.
Understanding Tick-Borne Disease Risk
Major Tick-Borne Diseases in North America:
Bacterial:
- Lyme Disease (most common)
- Rocky Mountain Spotted Fever
- Anaplasmosis
- Ehrlichiosis
- Tularemia
- Southern Tick-Associated Rash Illness (STARI)
Viral:
- Powassan Virus
- Colorado Tick Fever
- Heartland Virus
Parasitic:
- Babesiosis
- Relapsing Fever
Disease Transmission Timeline:
- Powassan Virus: 15 minutes – 4 hours
- Rocky Mountain Spotted Fever: 6-10 hours
- Lyme Disease: 36-48 hours
- Anaplasmosis: 12-24 hours
Key Point: Faster removal dramatically reduces infection risk
Tick Species and Disease Risk
Black-Legged Tick (Deer Tick) – Ixodes scapularis:
Size: Poppy seed (nymph) to sesame seed (adult)
Diseases: Lyme, Anaplasmosis, Babesiosis, Powassan
Peak Activity: May-July (nymphs), October-November (adults)
Habitat: Wooded areas, tall grass, leaf litter
American Dog Tick – Dermacentor variabilis:
Size: Watermelon seed when engorged
Diseases: Rocky Mountain Spotted Fever, Tularemia
Peak Activity: April-early September
Habitat: Grassy areas, trails, wood edges
Lone Star Tick – Amblyomma americanum:
Size: Similar to dog tick

Rocky Mountain Wood Tick – Dermacentor andersoni:
Diseases: Rocky Mountain Spotted Fever, Colorado Tick Fever
Habitat: Western US mountain regions
Peak Activity: March-July
Tick Behavior and Habitat
Quest Behavior:
Ticks don’t jump or fly—they "quest":
- Climb to tips of grass/shrubs
- Extend front legs
- Wait for host to brush against them
- Transfer instantly to host
Prime Tick Territory:
- Edges: Where woods meet grass
- Trails: Especially narrow paths through vegetation
- Tall grass: Above knee height
- Leaf litter: Fallen leaves in forests
- Stone walls: In wooded areas
- Overgrown areas: Unmaintained landscapes
Peak Risk Times:
- Season: May through September
- Daily: Dawn and dusk
- Weather: After rain, humid conditions
- Temperature: Above 45°F
Prevention Strategies
Clothing Protection:
Optimal Clothing:
- Light-colored clothing (easier to spot ticks)
- Long sleeves and pants
- Pants tucked into socks
- Closed-toe shoes
- Hat with brim
Fabric Treatment:
- Permethrin-treated clothing (lasts 70+ washes)
- DIY permethrin treatment for gear
- Remains effective when wet
- Kills ticks on contact
Repellent Application:
DEET (20-30% concentration):
- Apply to skin and clothing
- Reapply every 4-6 hours
- More effective than other options
- Safe when used as directed
Picaridin:
- Less odor than DEET
- Doesn’t damage synthetic materials
- Effective for 8-12 hours
- Pleasant to use
Natural Alternatives (Less Effective):
- Lemon eucalyptus oil
- Cedar oil
- Rosemary oil
Environmental Awareness:
- Stay on center of trails
- Avoid tall grass when possible
- Don’t sit directly on ground
- Check for ticks frequently during hike
- Avoid areas with deer sign
Tick Checks: Your Best Defense
During Activity Checks:
Every 2 hours, check:
- Arms and legs visible areas
- Clothing for crawling ticks
- Gear and packs
- Hiking partner’s back
Post-Activity Full Body Check:
Systematic approach:
- Scalp and hair – use mirrors or partner
- Behind ears – common attachment site
- Neck and collar area
- Armpits – warm, hidden areas
- Arms and forearms
- Chest and back
- Waist and belt line
- Groin area – high-risk location
- Behind knees
- Between toes
Use magnifying glass if available – nymphs are tiny
Proper Tick Removal Technique
The ONLY Correct Method:
Equipment:
- Fine-tipped tweezers (not fingers)
- Rubbing alcohol
- Magnifying glass if available
Step-by-Step Removal:
- Clean area around tick with alcohol
- Grasp tick with tweezers as close to skin as possible
- Pull steadily upward with even pressure
- Don’t twist or jerk – may leave mouthparts
- Don’t squeeze tick body – may inject pathogens
- Remove completely – check for mouthparts
- Clean bite site with rubbing alcohol
- Save tick in sealed container for identification
What NOT to Do:
Never use:
- Petroleum jelly
- Nail polish
- Heat (matches, cigarettes)
- Soap
- Essential oils
These methods:
- Don’t make tick detach
- May cause tick to regurgitate into wound
- Increase disease transmission risk
Post-Removal Documentation
Information to Record:
- Date and time of bite discovery
- Location where exposure likely occurred
- Tick identification (take photo if possible)
- Duration attached (estimate based on engorgement)
- Symptoms if any develop
- Removal method used
Tick Identification:
- Take clear photo before disposal
- Save tick in sealed bag with date/location
- Consider sending for testing if available
- Compare to online identification guides
Early Disease Recognition
Lyme Disease Warning Signs:
Stage 1 (3-30 days):
- Erythema migrans rash (bull’s-eye appearance)
- Flu-like symptoms
- Fever and chills
- Headache
- Muscle and joint aches
Stage 2 (weeks to months):
- Additional rashes
- Facial paralysis
- Heart problems
- Severe headaches
Stage 3 (months to years):
- Arthritis
- Neurological problems

The Bottom Line
Tick-borne diseases are increasing in incidence and geographic range. Climate change extends tick seasons and expands their habitat. Prevention through protective clothing, repellents, and frequent tick checks remains your best defense.
Remember: The smaller the tick, the greater the disease risk. Nymphal ticks are most dangerous because they’re hardest to spot but carry the highest pathogen loads. A tick bite isn’t an automatic sentence to illness, but vigilance and proper removal techniques can prevent weeks of suffering.
Check early, check often, remove properly, and seek medical care for any suspicious symptoms.
