Most visitors never meet most of this. Florida is a big state and its wildlife changes a lot from region to region - a cane toad is a South Florida backyard problem, a black bear is a central and north Florida one, and a crocodile only matters in the far south. These guides are here for the encounter you do have, not because one is likely.
Fire ants are one of Florida’s most common outdoor pet hazards.
They can sting:
- Dogs
- Cats
- Livestock
- Wildlife
- People
A single sting is painful.
A pet that disturbs a mound can receive many stings quickly.
Florida Has Invasive Fire Ants
The red imported fire ant is one of Florida’s major pest species.
UF/IFAS describes it as:
- Aggressive
- Reddish-brown to black
- About 1/8 to 1/4 inch long
- Capable of painful stings
Fire Ants Attack When the Nest Is Disturbed
When a mound is disturbed, many workers can emerge rapidly and sting the intruder.
A dog may disturb a mound by:
- Digging
- Lying down
- Stepping on it
- Sniffing through grass
Florida Mounds Can Be Hard to See
UF/IFAS notes that Florida’s sandy soils can produce less obvious mounds than heavier clay soils.
Do not assume there are no fire ants because you cannot see a large mound.
Where Fire Ants Nest
They can nest:
- Lawns
- Around trees
- Around stumps
- Under pavement
- Near buildings
- In rotting logs
- Utility areas
Check Dog Parks and Rental Yards
Before letting a dog run:
- Scan the grass
- Check around trees
- Look at fence lines
- Watch recently disturbed soil
This is especially useful at:
- Vacation rentals
- Campgrounds
- Dog parks
- Rest areas
If Fire Ants Swarm Your Dog
Move the dog away from the mound immediately.
Brush ants off carefully while protecting yourself.
Do not stand in the mound while trying to help the dog.
Where Dogs May Be Stung
Common exposed areas include:
- Paws
- Legs
- Belly
- Nose
- Lips
A dog lying on a mound may receive stings across a large area.
Watch for Allergic Reaction
Multiple stings can be more serious than one sting.
Seek urgent veterinary care if your pet develops:
- Facial swelling
- Difficulty breathing
- Collapse
- Severe weakness
- Widespread swelling
- Repeated vomiting
Call Your Veterinarian for Treatment Advice
Do not automatically give human:
- Antihistamines
- Pain medicine
- Steroid creams
without veterinary guidance.
Drug choice and dose depend on the animal.
Keep Pets Away From Treated Mounds
Fire-ant control products can also create pet hazards if misused.
Follow the pesticide label exactly.
Keep pets away for the required period.
There Is No Permanent One-Time Fix
UF/IFAS says no method permanently eliminates fire ants from an area.
Control may require:
- Broadcast baits
- Individual mound treatment
- Ongoing monitoring
Flooding Creates a Special Hazard
UF/IFAS warns that flooded fire ants can form floating masses.
After:
- Hurricanes
- Tropical storms
- Floods
keep pets away from floating debris and ant rafts.
This is especially important in Florida disaster cleanup.
Fire Ants After Hurricanes
Storm-damaged yards can contain:
- Displaced colonies
- Flooded ants
- Hidden mounds
- Debris
Keep pets supervised until the area has been checked.
Best Fire-Ant Safety Checklist
- Scan yard
- Avoid mounds
- Supervise digging dogs
- Move pet away immediately if ants swarm
- Watch for breathing or facial swelling
- Call veterinarian after significant reaction
- Follow pesticide labels
- Be extra careful after flooding
