South Florida’s hot, humid climate is a haven for unique wildlife, but some creatures—like the Bufo toad—can pose serious risks to pets, children, and even adults. Understanding these invasive amphibians and how to protect your household is key to staying safe in this tropical region. Here’s a deep dive into the dangers of Bufo toads and practical steps to manage their presence.
What Is a Bufo Toad?
The Bufo toad, also known as the cane toad, marine toad, or giant toad (Rhinella marina), is a large, invasive amphibian not native to Florida. Introduced in the 1930s to control pests in sugar cane fields, they’ve since exploded in population, thriving in South Florida’s warm, wet environment. These toads are typically 4 to 9 inches long, with grey-brown skin, slightly yellow bellies, and large, triangular glands on their shoulders. Unlike native Southern toads, which are smaller (3-4 inches) and have cranial crests, Bufo toads are stocky, poor jumpers with short legs, making them easy to identify.
Why Are Bufo Toads Dangerous?
Bufo toads are highly toxic at all life stages—eggs, tadpoles, and adults. They secrete a milky-white venom called bufotoxin from glands behind their eyes as a defense mechanism when threatened. This toxin is a potent neurotoxin and cardiotoxin, posing a severe threat, especially to pets:
- Risk to Pets: Dogs and cats often lick, mouth, or bite these toads, triggering the release of bufotoxin. Even a small amount can be lethal if untreated. Puppies are particularly vulnerable due to their playful nature. Symptoms include excessive drooling, red gums, head-shaking, crying, loss of coordination, seizures, and, in severe cases, death within hours.
- Risk to Humans: While the poison hasn’t been known to kill humans, it can cause skin and eye irritation if handled without protection. Ingesting toads or their eggs (e.g., eating boiled toad eggs) can be deadly.
- Ecological Impact: Bufo toads compete with native species for food and breeding grounds, eating anything from insects to small mammals. They lay 10,000 to 30,000 eggs per clutch, leading to population explosions that disrupt local ecosystems.
How to Recognize Bufo Toad Poisoning
If your pet has been outside, especially at night or after rain when Bufo toads are most active, watch for these signs of poisoning:
- Profuse drooling or foaming at the mouth
- Red, inflamed gums
- Difficulty walking or lack of coordination
- Seizures or convulsions
- Whining or distress
If you suspect exposure, act fast: rinse your pet’s mouth and paws with water (avoid letting them swallow the water), wash your hands thoroughly, and rush them to a vet. Time is critical—bufotoxin can kill a pet in as little as 30 minutes if untreated.
Why Are Bufo Toads So Common in South Florida?
South Florida’s climate—hot, humid, and rainy—creates ideal conditions for Bufo toads. They breed year-round in standing water like canals, ponds, and ditches, often found in urban, suburban, and agricultural areas. Recent reports, such as those from Palm Beach Gardens in 2019, highlight their rapid spread, with thousands clogging pools and yards after heavy rains. They’re drawn to light sources at night (which attract bugs) and pet food left outdoors, making residential areas prime targets.
How to Protect Your Home and Pets
While On Demand Pest Control does not offer Bufo toad removal services, here are proactive steps to reduce the risk:
- Remove Attractants: Feed pets indoors—Bufo toads are drawn to dog and cat food, leaving toxins in bowls. Clear bushy plants, clutter, and wood piles where toads hide.
- Eliminate Water Sources: Remove standing water from your yard, as toads breed in it. Cut grass regularly and fill holes around structures.
- Supervise Pets: Keep pets indoors at night and after rain, when toads are most active. Supervise outdoor play, especially with curious puppies.
- Install Barriers: A fine mesh fence extending 6 inches underground can block toads from entering your yard.
- Handle with Care: If you must remove a toad, wear latex, rubber, or nitrile gloves and eye protection. Florida law allows humane euthanasia on private property but prohibits relocation. The University of Florida recommends applying 20% benzocaine gel to the toad’s belly before freezing for humane disposal.

Final Thoughts
Bufo toads are a serious threat in South Florida, especially to pets, due to their toxic secretions and invasive nature. While they play a role in the ecosystem by eating pests, their impact on native wildlife and domestic animals outweighs their benefits. Staying vigilant, removing attractants, and knowing who to call for removal can keep your household safe. If you spot a Bufo toad, act cautiously—it’s a danger you don’t want to underestimate.
