It contains numerous glands known as parotid glands, which secrete a milky substance when the toad feels threatened or stressed. Toads are fascinating creatures that can be found in various habitats around the world. While many species of toads are harmless, there are certain types that can pose a serious threat to humans and pets.
Pet frogs and toads are commonly known to spread Salmonella to humans. Interestingly, the otters that eat these animals have learned to remove their skin first, in order to avoid ingesting the toxins. When an animal develops a defense response, its predator will surely learn to avoid it. To attract non-toxic toads to your garden, create a habitat with plenty of hiding spots, such as rocks, logs, and plants.
Colorado River Toads (Incilius Alvarius) are also known as Sonoran Desert Toads and are common in the southwestern United States and Northern Mexico. There is dark pigment visible on the chest and at the front of the back, close to the head. If you happen to touch a toad, ensure you wash your hands thoroughly before you touch anything else.
Yes, many toad species are poisonous to eat, though the level of toxicity varies by species. Most toads in the U.S., including the American Toad (Anaxyrus americanus), secrete toxins from parotid glands behind their eyes as a defense. These toxins, known as bufotoxins, can cause irritation if ingested or touched, affecting both predators and humans with symptoms like burning eyes, nausea, or skin irritation. However, bufotoxins from American Toads are generally mild and unlikely to be fatal to larger animals or pets, though they may still cause illness or discomfort if consumed.
How poisonous are true toads compared to other amphibians?
The toads you capture will need another, similarly-moist area to be relocated to, or they will not survive. This could be a nearby drainage, cattle tank, park, golf course, or anywhere you know there’s a little water and cover. If you know you could have some toads nearby, spend a little time on Google Maps to find an alternative place to take them.

While the efficacy of these treatments is still being debated, the use of toad toxins in medicine highlights the complex relationship between humans and amphibians. The good news is that most toads in the United States are only mildly toxic, though their secretions can cause some dramatic signs when they come into contact with a pet’s mouth. Excessive drooling, foaming at the mouth and pawing at the mouth are common signs of ingestion–if a toad is actually ingested, vomiting can occur as well. The Western toad can be fatal to humans if humans lick or try to eat the toad. They secrete poison from their glands and are very dangerous to dogs and cats.
- The exact mechanisms of this conversion are not fully understood, but it is believed to involve enzymatic reactions.
- In this article, we will discuss why it is important to be able to identify these toxic amphibians and provide you with some tips on how to do so.
- There’s no need to interact with a toad in nature, and any sort would likely cause the toad distress.
- Toads are thin-skinned and can easily be harmed or killed by chemicals in everyday products harmless to us.
- It is important to look for other indicators of toxicity as well.

All toads are poisonous, but some are more poisonous than others. Harlequin toad toxicity varies, and Common toads, American toads, and Midwife toads are mildly toxic. Almost all toads secret bufotoxin, with or without other toxins.
Bufotenin is a hallucinogenic with chemical properties similar to LSD. A standard-sized toad can eat around 3,200 insects per season, making them great for garden pest control. When they are tadpoles, they are herbivores and eat soft plant material or algae. Very similar in appearance to the Woodhouse’s Toad is the Great Plains Toad. It’s a stout-looking toad with a more reticulate, blotched pattern than the Woodhouse, but also often has a light colored stripe down the back.

They live in urbanized habitats and agricultural lands but also in some natural areas, including floodplain and mangrove swamps. Cane toads are native to South and Central America and were introduced into Palm Beach County to control pests in sugar cane fields, according to the University of Florida. The composition of sub-compounds in each toad’s unique bufotoxin mix can vary greatly.
- This allows the fast-acting toxin to directly enter the body and begin its wicked work.
- As long as your pet is conscious, rinse their mouth out with water for five to 10 minutes using a hose or other running water.
- The liver, in particular, can be highly toxic due to the accumulation of bufotoxins.
- In some cultures, toad venom has been used for centuries to treat various ailments, including skin conditions, pain, and even cancer.
- If you see a poisonous frog in your yard, you will want to move any pets and children away.
The severity of the symptoms depends on factors such as the type of toad and the amount of toxin ingested. In extreme cases, true toad poisoning can lead to respiratory distress and even death. While none of these pose the threat that the cane or Colorado River toads pose, all toads possess parotoid glands that secret a poisonous, milky substance to deter their predators.
In North America, the most precarious toads are the Cane Toad and the Colorado River Toad. See the below chart for descriptions of these two pernicious amphibians. The Colorado River toad is a native species, so its euthanasia isn’t sanctioned. There is no need to euthanize any other native toad species, as none poses a sufficient threat.
They can adapt to their environment, which is close to a semi-permanent water source. Tadpoles that ate shrimp were more likely to develop into aggressive, carnivorous forms. Over generations, this response appears to have become a fixed part of their development. To humanely euthanize a cane toad, generously apply benzocaine or lidocaine ointment or spray (found in drug and grocery stores) to the toad’s back or belly and freeze it overnight. Cane toads are currently found in central and south Florida, generally south of the I-4 corridor. You’re probably aware that Florida has battled invasive species for decades.
European green toads (Bufotes Viridis) are found in mountainous areas, deserts, urban areas, and other habitats in Europe, from France to Western Russia. Gulf coast toads (Incilius Valliceps) are native to eastern and southeastern Mexico and Central America. Their natural habitat includes pine flat woods, pine-oak woods, savannas with sandy soil, maritime forests, and oak scrub. They are common across the coastal plains of southeastern United States from Florida to southeast Virginia and eastern Louisiana. These toads are common from north Pakistan to Bangladesh to Sri Lanka, Thailand, Vietnam, Cambodia, Macau, and Malaysia, to name a few. They live up to 8,200 feet in the southern part of their range and are usually found in woodlands, wet locations, open countrysides, parks and gardens, and fields.
This can be exceptionally dangerous for your pet as some toads and frogs are more toxic than others and can cause serious harm. Males have a white belly and a loose flap of skin under the mouth, which is their vocal sac. If a dog bites or comes in contact with a cane toad, use a damp cloth or towel and wipe the inside of the dog’s mouth to make sure no toxins were swallowed, Gioeli told TCPalm. Symptoms of poisoning in pets include excessive drooling and extremely red what toads are poisonous gums, head-shaking, crying, loss of coordination and sometimes convulsions.
For this reason, toads have developed a defense in the form of toxins located on the skin, which makes them poisonous. While poisonous toads are not common in many regions, it is always a good idea to be cautious when encountering wild amphibians. Educating yourself about the local wildlife and taking precautions can help prevent accidental exposure to toxic species. Another trend is the rise in toad-related injuries among children and pets. In recent years, there have been numerous reports of children and pets becoming ill or even dying after coming into contact with poisonous toads.
