Why My Tree Frog Peed On Me

I’m sure almost everyone out there is familiar with a lot of myths on Frog peeing. Tree frog owners come across this incident quite often. There are a lot of reasons why your frog puts you into this unwanted situation.

Tree Frog peeing on your hand is a defensive mechanism. They do so to flee away from your hand. 

Since it’s a very common incident, every tree frog owner should know about every aspect of tree frog peeing. Continue reading this article if you want to know more about it.

Why Do Tree Frogs Pee When You Hold Them?

Here’s the major reason. When you hold a tree frog, it becomes afraid. It tries to escape from your captive. But when you don’t allow it to move or escape, the last thing it does is peeing on your hands.

Amphibians use different types of tactics to avoid predators. Poisonous toads and frogs secret poisons through their skin and mouth. But amphibians that are not poisonous tend to squirt fluid out of their body to scare the predators.

This is what happens when you hold a tree frog in your hands. It freaks them out and they consider you a potential threat. Except for these, there are other physiologic factors associated with their renal system and body fluid maintenance.

Why Do Tree Frogs Urinate Frequently?

Not only tree frogs. Every frog species possesses this physiological condition. Frogs have thin skin and they intake a lot of water. Since they leave inside or by the water bodies, the number of fluids present in their bodies sometimes exceeds their weight.

Research on frogs carried out by researchers of Charles Darwin University proved that frogs excrete foreign bodies through urine. As they are light weighted and jump frequently, many sharp elements penetrate their skin. Surprisingly enough, these foreign particles are engulfed and excreted through urine. Their Gall Bladder plays a vital role in this case.

For these reasons, they store a significant amount of urines and it becomes really tough for them to hold on to their pees when they are scared. The sphincters loosen and BOOM! Your hands faced a disaster.

Compositions Of Tree Frog Urine

The composition of tree frog urine is the same as other amphibians. Their kidneys eliminate harmful toxins and foreign particles through urine. They largely contain Urea and other nitrogenous waste products.

Since they intake a lot of water, their urine is hypotonic, diluted, and lower osmotic pressure.

How Does Tree Frog Pee look like?

If their kidneys are functioning properly, their urine looks almost like water. They smell bad and taste the worst. But during renal diseases or other metabolic dysfunctions, their urine may appear orange in color.

Is Tree Frog Pee Poisonous?

No. Tree frog urine is not poisonous because it doesn’t contain any harmful components. If we look at its composition, we will find components that are non-toxic and harmless. They excrete ammonia through Urea, which is chemically neutral.

They do not contain any parasite or harmful bacteria since they are purified in the kidneys, So here’s the assurance, if your pet frog pees on your hand, don’t freak out, it won’t kill you.

But ingesting Tree frog urine may have some effects. They include vomiting, stomachache, or other inflammations in your stomach.

Can Tree Frog Pee Make You Blind?

There’s no proof of this fact. By the data collected by scientists, Tree frog urine wouldn’t probably cause severe injury to your eyes. But it can cause some inflammation and irritation since urines are a bit acidic due to the presence of nitrogenous waste products.

So if it goes into your eyes, simply rinse your eyes thoroughly with water.

Is Tree Frog Pee Dangerous For Your Skin?  

There are a lot of myths about the effects of touching frogs or other amphibians. Many people believe that it can cause warts. But dermatologists and scientists have blown away this myth saying wart isn’t a result of amphibian Bacteria. Human bacteria are the major culprit of warts.

But Tree frogs and other frogs may have a parasite on their skin called ‘Salmonella’. Salmonella can cause some severe to chronic inflammation to the human body.

 In severe cases, it can also cause death. It causes vomiting, diarrhea, and abdominal cramps. Salmonella mainly spreads through the droppings of tree frogs.

Should You Touch Your Tree Frogs Often?

Frogs and amphibians are not the kind of pet you can touch every day. The frog’s skin is very sensitive to touches. They absorb literally everything through their skin. So it’s always risky to touch frogs.

  • If you freak them out they will pee on your hand.
  • They can spread Salmonella Bacteria through feces and urine.
  • Some frogs may be poisonous, they can even cause death.

Frogs are very vulnerable to touches because:

  • It can cause serious stress.
  • They will absorb any chemical substance from your skin. It can be soap, any kind of powder, chemicals that can eventually cause death.
  • If you squeeze them hard it may cause internal injuries.
  • If they jump from a height, it will have abrupt effects on the frogs’ organs.

If a frog pees on you, it’s generally not a cause for concern, as frog urine is typically harmless to humans. However, you may want to take some basic precautions and follow these steps:

  1. Wash the affected area: Use soap and clean water to wash the area where the frog urinated. This will help remove any potential contaminants and reduce the risk of infection. Make sure to rinse thoroughly.
  2. Avoid touching your face: After handling the frog or the area where it urinated, avoid touching your face, especially your eyes, nose, and mouth, until you have thoroughly washed your hands.
  3. Clean your clothing: If the urine got on your clothing, wash the affected garments as soon as possible to remove any residue.
  4. Monitor for any adverse reactions: While it’s unlikely, some people may have skin sensitivities or allergies that could lead to mild skin irritation after contact with frog urine. If you notice any unusual skin reactions or discomfort, consult a healthcare professional.
  5. Handle frogs with care: If you’re handling frogs, whether in the wild or as pets, do so gently and avoid any sudden movements that could startle them. Frogs may urinate as a defense mechanism when they feel threatened or stressed.

do frogs pee when scared?

Frogs can release urine when they are scared or feel threatened. This behavior is part of their defense mechanism. When a frog perceives a potential threat, it may release urine as a way to deter predators or to make itself less appealing as prey. The sudden release of urine can be a distraction or cause discomfort for a potential predator, giving the frog a chance to escape.

where do frogs pee from?

Frogs, like most amphibians, do not urinate in the same way that mammals do. They lack specialized structures like kidneys and a urinary bladder. Instead, frogs excrete waste, including ammonia and urea, primarily through their skin.

Frogs have a pair of small structures called “urostyle” located at the base of their cloaca, which is a common opening for both excretion and reproduction. The waste products diffuse through the frog’s skin and are expelled into the environment. This process is called “cutaneous respiration” and is essential for maintaining their water and electrolyte balance.


Tree frogs are the best kind of frog you can pet. The problems that you are facing with your tree frog are common in other frog species too. So before their natural instincts freak you out, try to learn more about them.

Peeing is a natural defensive mechanism of frogs. So do not worry about this too much. Try to avoid things that will lead to this problem. Let your frog live happily in that dark corner of your tank and you are good to go.
