Think Winter Kills Ticks? Here’s What the Latest Research Says

Ticks are now a year-round concern in the Northeast.  Learn more about what organic land care can do…

The Myth: Winter Gets Rid of Ticks  

Many homeowners, landscapers, and even property managers assume that cold New England winters naturally reduce tick populations. “Cold temperatures can and do impact survival in deer ticks, lone star ticks, and American dog ticks. When directly exposed to open air temperatures around 7-10°F, most individuals of these species will die within 2 hours. There is undoubtedly some degree of mortality that tick populations experience during the winter. It’s just not enough.”

Recent insights from UMass Extension highlight a growing reality: ticks are not just surviving winter; they can remain active throughout it.

The Reality: Ticks Are a Year-Round Pest

Research shows that certain tick species, especially deer ticks, can remain active whenever temperatures rise above freezing, even in the middle of winter.

Snow cover, rather than killing ticks, can actually protect them by insulating the ground and preventing extreme temperature swings. On top of that, species like the lone star tick are expanding their range northward, driven in part by changing climate conditions.

What This Means for Landscapers, Schools, and Municipalities  

“With ticks, it’s all a numbers game…Ticks lay about 2,000-10,000 eggs, depending on the species. Each female lone star tick lays about 3,000 eggs. Even if only a small percentage of her ticks survive the winter, the chances of some progeny surviving are increased through sheer volume.” (UMASS Extension)

Tick populations are heavily influenced by:

  • Habitat conditions
  • Moisture levels
  • Host availability (deer, rodents, etc.)
  • Landscape design and maintenance practices

This is where organic land care plays a critical role.

The Organic Land Care Perspective: Focus on Habitat, Not Just Treatment  

Instead of reacting to ticks with short-term chemical controls, organic land care takes a systems-based approach. We must understand the conditions that allow ticks to thrive in the first place.

Ticks prefer:

  • Damp, shaded environments
  • Dense vegetation and leaf litter
  • Overgrown edges between woods and turf

So the goal becomes simple: Make your landscape less inviting to ticks.

Practical Steps to Reduce Tick Habitat Naturally  

As tick activity becomes less seasonal and more climate-driven, the industry is shifting away from reactive treatments toward proactive landscape management. Organic land care provides a framework that addresses the root causes instead of just the symptoms. Whether you manage a school campus, municipal property, or residential landscape, these strategies make a measurable difference.

1. Manage Leaf Litter and Organic Debris  

Ticks rely on moist environments to survive. First,  reduce excess leaf litter, especially along edges, to limit their habitat.

2. Improve Sunlight and Airflow  

Prune back dense plantings and thin overgrown areas to allow more sunlight to reach the ground. Dry, sunny conditions are far less favorable for ticks.

3. Maintain Clear Edges Between Lawn and Woods  

Define transitions between turf and wooded areas using mulch, gravel, or maintained borders. Notably, this reduces the “edge habitat” where ticks are most concentrated.

4. Avoid Overly Dense, Damp Turf  

Healthy, balanced turf is key. We don’t want turf overly thick or constantly wet. Organic soil management helps regulate moisture and improve resilience.

5. Support Biodiversity and Ecological Balance  

Healthy ecosystems can help regulate pest populations over time. An organic approach supports soil biology, plant health, and long-term stability — all of which contribute to a less hospitable environment for ticks.

6. Use Targeted, Organic Pest Management When Needed  

In higher-risk areas, targeted applications can help reduce tick pressure as part of a broader strategy. As such, rather than relying on synthetic chemicals, products like Cedar Cure utilize cedarwood oil — a minimum-risk, plant-based active ingredient — work by:

  • Exposure to cedarwood oil triggers the erosion of the exoskeleton
  • Interfering with insect sensory systems and stifling their ability to detect food
  • Disrupting breeding cycles
  • Encouraging pests to relocate away from treated areas

When used consistently and in combination with habitat management, this type of approach can help reduce tick populations while maintaining a safer environment for people, pets, and pollinators.

PJC’s Practical Approach  

At PJC Organic, we focus on building healthier landscapes from the ground up, while also offering tools to manage pest pressure when needed.

Therefore, our approach includes:

  • Soil health programs that improve turf resilience
  • Organic fertility that supports balanced growth
  • Cultural practices that reduce tick habitat
  • Targeted organic pest management solutions like Cedar Cure for added protection

We don’t rely on heavy chemical treatments. We combine prevention, habitat management, and organic inputs to create landscapes where ticks are less likely to thrive.
