2026 New York Pest Calendar: What to Expect Each Season in Albany, Saratoga & Kingston
Why Seasonal Awareness Helps Prevent Pest Infestations
Our New York pest calendar is a seasonal guide that explains when different pests become active throughout the year. In Upstate New York, pest activity follows predictable seasonal patterns driven by temperature, moisture, and shelter availability.
Understanding seasonal pests in NY can help homeowners:
- Identify pest risks before infestations begin
- Take preventative steps at the appropriate time of year
- Avoid emergency treatments caused by delayed response or lack of planning
In the Capital Region and Hudson Valley, seasonal awareness is one of the most effective tools for long-term pest prevention.
Winter (January–March): Rodents and Overwintering Pests
Winter pest activity in New York is primarily focused on indoor survival. Cold temperatures push pests to seek warmth, food, and shelter inside homes.
Common Winter Pests:
- Mice and rats
- Stink bugs and lady beetles
- Cluster flies
- Occasional spiders and pantry pests
Rodents are the most significant winter concern. Once inside, they can cause structural damage, contaminate food, and reproduce rapidly.
Early indicators of winter pest activity include:
- Scratching or movement inside walls
- Droppings in kitchens, basements, or garages
- Pests appearing near heat sources
Spring (April–June): Termites, Ants, and Ticks
Spring marks the beginning of peak pest reproduction in Upstate NY. As temperatures rise, insects emerge and colonies flourish.
Common Spring Pests:
- Termites during swarm season
- Ants entering homes in search of food
- Ticks becoming active in yards and wooded areas
Termite swarms are a key warning sign. Seeing winged insects indoors during spring often indicates a nearby colony, even if damage is not yet visible.
Spring is the most critical season for preventative pest control because early intervention reduces summer infestations later on.
Summer (July–September): Mosquitoes, Wasps, and Carpenter Ants
Summer is the highest pest pressure period in the Capital Region and Hudson Valley. Warm temperatures and humidity create ideal conditions for rapid pest population growth.
Common Summer Pests:
- Mosquitoes breeding in standing water
- Wasps and hornets building large nests
- Carpenter ants active in damp or damaged wood
Mosquito activity increases after rainfall, while stinging insects become more aggressive as nests grow. Carpenter ants are often mistaken for termites but can still cause substantial structural damage over time.
Unchecked summer pest activity often leads to recurring problems year after year, like clockwork.
Fall (October–December): Stink Bugs, Cluster Flies, and Rodents
Fall pest behavior in NY is driven by preparation for winter. Pests seek shelter in wall voids, attics, and basements before temperatures drop.
Common Fall Pests:
- Stink bugs clustering on exterior walls
- Cluster flies gathering near windows and attics
- Rodents returning to structures for warmth
Fall is the most effective time to focus on proactive exclusion and sealing entry points before pests move indoors. Preventative action during this season significantly reduces winter infestations.
