New Jersey Is Tick Country
Ticks are established throughout New Jersey, and the risk is not limited to deep woods or midsummer hikes. Homeowners can encounter ticks along lawn edges, trails, brush, leaf litter, pet routes and other places where people, wildlife and shaded vegetation overlap.
Rutgers identifies the blacklegged tick, lone star tick and American dog tick as the three species in New Jersey most associated with human disease transmission. The invasive Asian longhorned tick is also established in the state and can become abundant in grassy areas and on animals.

Common Tick Species in New Jersey
Blacklegged Tick
Also called the deer tick. It is the tick associated with Lyme disease in New Jersey and can also transmit pathogens associated with anaplasmosis, babesiosis, hard tick relapsing fever and Powassan virus.
Lone Star Tick
An aggressive human-biting tick that has expanded northward in New Jersey. It is associated with ehrlichiosis and can also be relevant to alpha-gal syndrome.
American Dog Tick
A familiar larger tick that often uses grassy or brushy habitat and can transmit the agent of Rocky Mountain spotted fever.
Asian Longhorned Tick
An invasive tick first recognized as established in the U.S. in New Jersey. It can reproduce without mating and may build very large populations on livestock and other animals.
When Is Tick Season in New Jersey?
There is no single start and stop date for all ticks. Different species and life stages peak at different times. Rutgers notes that lone star ticks are active in New Jersey from roughly March through October, while blacklegged ticks can remain active during cool weather and winter warmups.
That means “tick season” is better thought of as a changing year-round risk than as one short summer window. Spring and early summer are especially important for tiny nymphal blacklegged ticks, while adult blacklegged ticks can be encountered in cooler months.
Why Ticks Show Up in Residential Yards
Ticks do not fly or jump into a property. They arrive on wildlife and pets, or they are already present in suitable habitat. Deer are important hosts for adult blacklegged ticks, while mice and other small mammals can play important roles in the tick life cycle and in maintaining pathogens such as the bacteria that cause Lyme disease.
Ticks are vulnerable to drying out, which is why shaded, humid areas matter. Leaf litter, overgrown groundcover, brush lines, woodlines and tall vegetation can create protected microhabitats.

Yard Control Does Not Replace Personal Tick Prevention
Even a well-maintained or professionally treated property cannot prevent every tick encounter. People and pets can pick up ticks at parks, trails, sports fields, vacation properties and other outdoor locations.

What If You Find an Attached Tick?
The CDC advises removing an attached tick as soon as possible rather than waiting for medical care just to remove it. Use tweezers close to the skin and pull with steady, even pressure. Watch for rash, fever or other concerning symptoms afterward and contact a healthcare professional if they develop.

Reducing Tick Pressure Around Your New Jersey Home
Good yard maintenance and targeted professional treatment can reduce tick habitat and add a layer of protection around the areas your family uses most. Bite Back focuses on common tick zones such as wooded edges, fence and brush lines, shaded landscaping, groundcover, under decks and pet routes.
FAQs About Ticks in New Jersey
Are ticks active in New Jersey during winter?
Some ticks can be active during mild winter weather. Blacklegged ticks in particular may become active when conditions are favorable, so prevention should not be limited to summer.
What tick spreads Lyme disease in New Jersey?
The blacklegged tick, also known as the deer tick, is the tick associated with Lyme disease transmission in New Jersey.
Do deer cause Lyme disease?
Deer are important hosts for adult blacklegged ticks and help support tick reproduction, but deer do not infect ticks with the Lyme disease bacteria. Small mammals such as white-footed mice are important reservoirs.
Where are ticks most likely to be in a yard?
Ticks are often associated with wooded edges, leaf litter, brush, tall vegetation, dense groundcover and other shaded, humid transition zones.
