Tick Issues and Common Tick Species in North Central New Jersey

North Central New Jersey  including areas such as Morris County, Somerset County, Hunterdon County, and surrounding communities is well known for consistent tick activity. Wooded neighborhoods, rolling terrain, preserved open space, and suburban development combine with humid summers and mild shoulder seasons to create ideal conditions for ticks to thrive.

Tick encounters are common from early spring through late fall, particularly for residents, pet owners, hikers, and those spending time outdoors near wooded or brush-heavy areas.

1. Blacklegged Tick (Deer Tick)

 The most common and medically significant tick species in North Central New Jersey.

Key traits:

• Prefers wooded areas, leaf litter, and shaded yard edges 
• Nymphs are extremely small and most active in spring and early summer 
• Adult ticks peak again in fall 
• Known to transmit Lyme disease, anaplasmosis, and babesiosis 

Frequently found in areas with deer and small mammal activity

2. American Dog Tick

 Widespread throughout North Central New Jersey, especially in open and grassy areas.

Key traits:

• Most active from late spring through summer 
• Found in grassy fields, park edges, trails, and roadside vegetation 
• Primary vector for Rocky Mountain spotted fever in New Jersey 

Larger size makes it easier to detect on people and pets

3. Lone Star Tick

 An increasingly common tick species across New Jersey.

Key traits:

• Adult females display a distinctive white “lone star” marking 
• Aggressive host-seeking behavior compared to other tick species 
• Expanding northward and becoming more established in the region 
• Known to transmit ehrlichiosis 
• Associated with alpha-gal syndrome, a red meat sensitivity linked to tick bites

Several regional factors contribute to ongoing tick activity:

• Extensive wooded areas and leaf litter that retain moisture 
• High deer and rodent populations that support tick life cycles 
• Humid summer conditions that extend tick survival 
• Mild spring and fall temperatures that lengthen active seasons 
• Suburban neighborhoods bordering natural areas increasing exposure 

These conditions allow multiple tick species to remain established throughout the region
