Fall in Central Florida signals a shift—not just in the weather, but in the behavior of local wildlife, especially squirrels. While Florida’s winters are mild compared to other states, squirrels still gear up for the cooler months by storing food, nesting in cozy spots, and even invading attics and garages. For homeowners, this means an increased risk of squirrel encounters, property damage, and potential pest control challenges.
Squirrel Behavior in Central Florida During Fall and Early Winter
1. Food Hoarding: The Squirrel Pantry
Squirrels are preparing for scarcity, even in Florida’s mild climate. As fall arrives, they intensify their food hoarding behavior, burying nuts, seeds, and even fruits in multiple locations. This instinct is called caching, and it’s essential for their survival during cooler months when food sources become less abundant.
What they hoard: Acorns, hickory nuts, pecans, and even birdseed from feeders.
Where they hide it: Lawns, gardens, flower pots, and even under roof shingles.
2. Nesting in Cozy Spots
As temperatures drop, squirrels seek warm, sheltered nesting sites. In Central Florida, this often means:
Attics and garages (especially in residential homes)
Wall voids and crawl spaces (common in older buildings)
Tree cavities and dense foliage (for tree squirrels)
Unlike some rodents, squirrels don’t hibernate, but they do reduce activity during the coldest weeks, relying on their stored food and insulated nests.
3. Increased Aggression and Territorial Behavior
Fall is also mating season for some squirrel species, leading to increased aggression as males compete for mates. You may notice:
Chattering and tail-flicking as squirrels warn off intruders.
More visible activity during daylight hours as they search for food and nesting sites.
4. Preparing for “Winter” in Florida
While Florida’s winters are far from harsh, squirrels still adapt their behavior to conserve energy:
They spend more time resting in nests during cooler days.
They rely on stored food rather than foraging as frequently.
Fun Facts About Central Florida Squirrels
Super Memory: Squirrels have an incredible ability to remember where they’ve hidden thousands of food items, even months later.
Built-in GPS: They use landmarks, scent, and even the position of the sun to navigate back to their caches.
Teeth That Never Stop Growing: A squirrel’s incisors grow continuously, so they must gnaw on hard objects (like nuts and wood) to keep them trimmed.
Swimming Pros: Gray squirrels are excellent swimmers and can cross water bodies to escape predators or find food.
Social Climbers: Squirrels often live in communities and communicate with chirps, tail signals, and even scent markings.
Why Squirrels Become a Pest Control Issue in Fall and Winter
Property Damage: Squirrels chew through wood, insulation, wiring, and even drywall to create nests or access attics.
Fire Hazards: Gnawed electrical wires can lead to short circuits or fires.
Noise and Disturbance: Scurrying in walls or attics can be loud and disruptive, especially at night.
Health Risks: Squirrel droppings can carry histoplasmosis, a fungal lung infection.
Garden and Landscape Damage: Their digging and caching can ruin lawns and flower beds.
How to Protect Your Property from Squirrels This Fall and Winter
For Homeowners:
Seal Entry Points: Inspect your home for gaps in the roof, soffits, vents, and chimneys. Use steel mesh, caulk, or metal flashing to block access.
Trim Tree Branches: Keep branches at least 10 feet away from your roof to prevent squirrels from jumping onto your home.
Install Chimney Caps: Prevent squirrels from nesting in your chimney by using a secure cap.
Use Squirrel-Proof Feeders: If you feed birds, use weight-sensitive feeders that close when a squirrel climbs on.
Store Firewood Away: Keep firewood at least 20 feet from your house and elevate it off the ground.
Check Attics and Crawl Spaces: Look for signs of nesting (chewed holes, droppings, or nests) and remove them promptly.
For Commercial Properties:
Inspect Roofs and Vents: Focus on loading docks, storage areas, and HVAC systems, where squirrels often enter.
Secure Trash Bins: Use rodent-proof bins with locking lids to deter squirrels from scavenging.
Install Door Sweeps: Ensure all exterior doors, including garage doors, have tight-fitting sweeps.
Schedule Regular Inspections: Partner with a pest control professional to monitor and prevent squirrel activity.
When to Call a Professional
If you notice:
Persistent scratching or scurrying in your walls or attic
Chewed entry points or nests in hidden areas
Squirrel droppings or urine stains in your home
A licensed pest control expert can safely remove squirrels and seal entry points to prevent future infestations.
