Southeastern Louisiana, including New Orleans, Metairie, Kenner, River Ridge, Gretna, Harvey, Chalmette, and surrounding Jefferson and Orleans Parish communities, provides ideal conditions for tick activity. Tree-lined neighborhoods, wetlands, shaded residential areas, and expanding suburban development combine with long, humid summers and generally mild winters to support tick populations for much of the year.
Ticks are frequently encountered by residents, pet owners, outdoor enthusiasts, and yard maintenance crews—especially in backyards, parks, walking paths, and properties that border wooded areas, tall grass, or dense vegetation.
One of the most medically significant tick species found in the New Orleans area.
Key traits:
Prefers wooded areas, leaf litter, shaded yard edges, and dense ground cover
Nymphs are extremely small and most active in spring and early summer, making them easy to overlook
Adult ticks often show increased activity again in fall
Known to transmit Lyme disease, anaplasmosis, and babesiosis
Frequently associated with areas that have deer populations and small mammal activity
Common throughout coastal Louisiana, particularly in open grassy areas and along transitional edges between lawns and wooded spaces.
Key traits:
Most active from late spring through summer
Frequently found in grassy fields, park perimeters, trails, roadside vegetation, and unmanaged lots
Known vector for Rocky Mountain spotted fever in Louisiana
Larger size makes it easier to detect on people and pets compared to smaller tick species
Lone Star Tick (Amblyomma americanum)
A very common and well-established tick species throughout New Orleans and coastal Louisiana.
Key traits:
Adult females display a distinctive white “lone star” marking on their backs
Known for aggressive host-seeking behavior compared to many other tick species
Thrives in warm, humid climates and is widespread across the South
Known to transmit ehrlichiosis
Associated with alpha-gal syndrome, a red meat sensitivity linked to tick bites
Residents are more likely to encounter ticks in:
Tree-lined neighborhoods and shaded property edges
Parks, walking paths, and neighborhood green spaces
Overgrown yards and unmanaged fence lines
Areas near bayous, canals, drainage ditches, and wetlands
Properties with frequent raccoon, rodent, or other urban wildlife activity
Dog parks and outdoor recreation areas
Early Spring: Nymph-stage blacklegged ticks become increasingly active as temperatures and humidity rise
Late Spring–Summer: American dog ticks and lone star ticks are common in open grassy areas and landscaped yards
Fall: Adult blacklegged ticks and lone star ticks remain active as long as temperatures stay mild
Winter: Activity slows during cooler periods, but Southeast Louisiana’s mild winters allow ticks to remain active on warmer days, especially beneath leaf litter, mulch, and dense ground cover
