Keene's Hidden Tick Calendar: Why Spring AND Fall Are High-Risk Seasons for NH Families
Most people picture tick season as a single stretch of hot summer days when kids are running through tall grass and dogs are bounding through the woods. It is a reasonable assumption, but in New Hampshire, it is also a dangerously incomplete one. If you live in or around Keene, the reality is that blacklegged deer ticks are active during two distinct windows every year, and missing either one puts your family and pets at real risk.
Keene Pest Control LLC has been helping Monadnock Region homeowners understand and respond to this two-season threat, and the data behind it has never been more urgent.
Why New Hampshire Has One of the Country's Highest Lyme Disease Rates
New Hampshire consistently ranks among the top states in the country for Lyme disease cases per capita. The reason is straightforward: the state's wooded landscape, abundant deer population, and increasingly mild winters create near-perfect conditions for blacklegged tick survival and reproduction.
A landmark study published by Dartmouth researchers in January 2025 found that 50% of adult blacklegged ticks in Northeastern states, including New Hampshire, carry the bacteria that causes Lyme disease. Even younger nymph ticks, which are roughly the size of a poppy seed and nearly impossible to spot on skin, carry it at a rate of up to 25%. These numbers are not meant to alarm, but they do make a compelling case for treating tick prevention as a year-round priority rather than a summer afterthought.
The Two Tick Seasons You Need to Mark on Your Calendar
Season One: Spring (Peaks in May)
As temperatures climb above freezing and the landscape around Cheshire County starts greening up, adult blacklegged ticks that survived the winter become active. These are the larger ticks that are somewhat easier to spot, but they are also the ones most likely to be carrying Lyme disease bacteria.
The spring season typically peaks in May, which aligns almost perfectly with the time Keene families are heading back outside for gardening, yard work, and hiking on trails like those around Surry Mountain Lake.
Season Two: Fall (Peaks in October)
This is the season most homeowners completely overlook. After a summer of feeding and developing, a new generation of nymph and adult ticks becomes active again in the fall. October is the second peak of tick activity in New Hampshire, and because people tend to drop their guard after summer ends, it is arguably the more dangerous of the two seasons. Cooler temperatures do not eliminate ticks. Blacklegged ticks remain active in temperatures just above freezing, and they will continue seeking a host on mild fall days well into late November.
Your Property Is a Tick Habitat If You Are Not Managing It
It is easy to think of ticks as a "woods problem," but the truth is that the edge zones between your lawn and any wooded areas, shrubs, leaf piles, or overgrown ground cover are exactly where ticks prefer to wait for a passing host. In Keene and surrounding towns like Walpole and Swanzey, properties with mature trees, stone walls, and natural landscaping are particularly inviting environments for tick populations to establish themselves close to the home.
Simple habitat adjustments can reduce tick pressure:
- Keep grass trimmed short, especially along fence lines and wooded borders
- Remove leaf litter and brush piles from near the home
- Create a mulch or gravel barrier between lawn areas and wooded sections
- Check pets thoroughly after every outdoor trip
These steps help, but they do not eliminate the problem on their own.
Why Timing Your Professional Treatment Matters
Because of the two-season tick pattern, the most effective tick control in Keene NH follows a two-treatment schedule aligned with each peak period. A spring application targeting active adult ticks (ideally in April, ahead of the May peak) paired with a fall application before the October surge gives your yard consistent protection during the windows when exposure risk is highest.
Professional treatments are designed to reach the shaded, humid microhabitats where ticks actually spend most of their time. This includes wooded edges, under decks, around stone walls, and along fence lines. Store-bought repellent sprays and perimeter products applied casually around a yard rarely penetrate these zones effectively enough to make a meaningful difference in tick populations.
Modern pest management approaches also lean heavily on Integrated Pest Management (IPM) principles, a method actively promoted by the New Hampshire Department of Agriculture. IPM focuses on targeted, ecologically responsible treatments that reduce chemical use while achieving long-term pest reduction. This means solutions that are safer for children, pets, and the local wildlife that makes this region so appealing to live in.
Protect Your Family Before Both Seasons Hit
Tick awareness has come a long way, but the two-season reality is still something many Keene-area homeowners learn about only after someone in the family has been bitten. Getting ahead of both the spring and fall peaks with professional yard treatment is one of the most practical steps you can take to reduce your family's risk throughout the year.

Frequently Asked Questions
When are ticks most active in New Hampshire?
Blacklegged ticks in New Hampshire have two active seasons. The first peaks in May during spring, and the second peaks in October during fall. Ticks can remain active on mild days well into late November, so it is important not to let your guard down after summer ends.
How likely is a tick in my yard to carry Lyme disease?
According to a Dartmouth study published in January 2025, approximately 50% of adult blacklegged ticks in the Northeast carry the bacteria that causes Lyme disease. Nymph ticks carry it at a rate of up to 25%.
Are tick treatments safe for my kids and pets?
Yes. Professional tick treatments using Integrated Pest Management (IPM) methods are designed to be targeted and low-impact, minimizing exposure risks to children, pets, and beneficial wildlife while still delivering effective control.
How often should I have my yard treated for ticks?
For homes in the Keene area, a two-treatment schedule is recommended: one in spring (April is ideal) and one in early fall (September to early October). This timing aligns with the two peak activity seasons for blacklegged ticks in New Hampshire.
Can I just use store-bought tick sprays?
Over-the-counter products can offer some surface-level repellency, but they rarely reach the shaded, humid areas where ticks actually hide and breed, such as wooded edges, stone walls, and under decks. Professional treatments are formulated and applied specifically to target these zones.
