Certain foods should not be given to your pet crested gecko in its diet as they can have long-term negative impacts on its health. Here are items that are toxic to crested geckos.

5 Toxic Vegetables and Food To Crested Geckos

Cucumber

The leaves and skin of a cucumber can cause impaction in your crested gecko – this is a health condition in which the food ingested by your crested gecko gets stuck in its intestine and your pet is unable to pass it through its body via defecation.

Lettuce

Lettuce leaves can again lead to impaction if not given properly – and they don’t have enough nutritional value either.

So, it’s best to find alternatives to lettuce that have a good content of vitamin A and can be fed to your crested gecko without the risk of impaction.

Spinach

Spinach is high in concentration of oxalic acid and should not be used in the diet of crested geckos.

This is because a higher concentration of oxalic acid or oxalates leads to an obstruction in the absorption of calcium in the body of crested geckos.

This leads to the deficiency of calcium in crested geckos and can lead to health conditions like metabolic bone disorder.

Ants

Ants should not be fed to your crested gecko as firstly they have almost no nutritional value, but also the stings or bites of ants can hurt your pet.

Baby Foods With Citric Acid

Baby foods with high content of citric acid or vitamin C should also be avoided.

Higher levels of acidity lead to poor digestion and gastrointestinal problems in crested geckos, and a high concentration of Vitamin C can cause diarrhea.

5 Chemicals Toxic To Crested Geckos

Certain chemicals present in everyday items like cleaning solutions or some food items can be toxic to crested geckos.

Phenols

Phenols are present in cleaning solutions and are toxic to crested geckos.

Cleaning solutions containing phenols should be avoided when cleaning the enclosure of your pet crested gecko or the room in which the enclosure is kept. Also, avoid any cleaners that have a pine scent.

Some people may use cedar or pine shavings to make the bedding of the tank for their pets – crested gecko owners should avoid this as well because both these materials have high levels of phenols.

And even if accidentally ingested by your pet, it can lead to fatal health conditions and even death.

Insecticides

Insecticides are brimming with chemicals that are meant to be toxic to insects and pests.

Considering how many of these insects are actually food for crested geckos, the same chemicals can be harmful to the health of crested geckos too.

So, avoid using insecticides in the enclosure or the room where the enclosure is kept.

Bleach

Bleach – both in powder form and as vapors – is harmful to both humans and crested geckos. But the intensity of harm caused is greater in crested geckos.

Bleach is hazardous to crested geckos and inhaling the vapors or fumes of bleach can cause respiratory problems in crested geckos.

Persin

Persin is a chemical compound found in avocados. Ingesting high levels of persin via avocados can lead to fatal health conditions, and in worst cases, even death.

This effect is seen in birds and small reptiles like crested geckos, leopard geckos, and other kinds of smaller pet reptiles as well.

Formaldehyde

Formaldehyde, again an active ingredient in most cleaning solutions, has a high level of toxicity when it comes to the health of crested geckos.

Instead of using common cleaners that have a high concentration of formaldehyde, it is recommended to go for reptile-safe disinfectants to clean the enclosure and the room in which the enclosure is kept.

5 Plants Toxic To Crested Geckos

Some certain plants and seeds should not be fed to crested geckos as those are toxic and cause problematic health conditions in the short or long term.

Morning Glories

The morning glory plant and flower contain high levels of hallucinogens and a toxic level of nitrates. So, if accidentally ingested by your pet crested gecko, it can lead to fatal health conditions.

Hyacinths

Hyacinth bulbs are poisonous even to human beings – even we are advised to use gloves when handling hyacinth.

This makes it all the more dangerous for crested geckos. Moreover, hyacinths have a very high level of oxalic acid content.

Too much oxalic acid impedes the absorption of calcium in crested geckos – which means that if your crested gecko accidentally ingests even a small amount of hyacinth, it can lead to health problems.

Periwinkles

Even small amounts of periwinkle being ingested by your pet crested gecko can cause symptoms like vomiting and intestinal problems.

When ingested in larger quantities, periwinkle can cause severe health problems like nerve damage, kidney damage, liver failure, and a sudden drop in blood pressure.

English Ivy

English ivy berries and leaves are toxic to humans and many animals alike – including crested geckos. If your pet crested gecko ingests the leaves or berries of English ivy, it can cause severe vomiting.

Oak Trees

Oak is harmful in two ways – firstly, oak leaves can cause choking or impaction in crested geckos, and secondly, oak contains a substance called gallotannin or oak tannins, which can be poisonous and toxic when ingested by crested geckos.

5 Fruits Toxic To Crested Geckos

While crested geckos are frugivorous, certain fruits need to be avoided at all costs as they can be very toxic to them.

Citrus Fruits

Citrus fruits have a higher concentration of oxalic acid and vitamin C.

High levels of oxalic acid in the body impede the absorption of calcium in the body of a crested gecko, leading to calcium deficiency and subsequent health conditions such as metabolic bone disorder or unviable, improperly calcified eggs while breeding.

Moreover, too much vitamin C in the diet of a crested gecko can lead to diarrhea.

So, it is always better to avoid citrus fruits altogether – the nutritional requirements of oxalic acid and vitamin C in the crested gecko’s body are fulfilled comfortably by other fruits that have lower concentrations of these substances.

Fruits With High Content Of Oxalic Acid

Many non-citrus fruits also have a very large content of oxalic acid – at least higher than what is required by a crested gecko.

Fruits like raspberries and dried fruits like walnuts, macadamia nuts, pistachios, almonds, and cashews are known to have high concentrations of oxalic acid.

These fruits should also be kept out of the diet plan of a crested gecko.

Avocado

While avocados have a lower concentration of oxalic acid and are a good source of healthy fats, these should also be avoided when charting a diet plan for your pet crested gecko.

The reason behind this is the presence of a substance called persin – a fungicidal toxin – that can harm the health of crested geckos.

Avocados

The research done till now has shown that not only is persin toxic to birds and crested geckos, but when ingested in large amounts, it can even lead to the death of your pet crested gecko.

Rhubarb

Even rhubarb should be avoided due to the higher content of oxalic acid.

Even rhubarb in the diet can lead to obstructions in the absorption of calcium in the body, leading to calcium deficiency and related disorders and health conditions.

Tomato Fruit And Plant

Tomato fruit and plant are again very closely related to citrus fruits and must not be included in the diet of your pet crested gecko as it can harm the long-term health of your pet.

Tomatoes are not native to the natural habitat of crested geckos, i.e., the rainforests of New Caledonia.

Moreover, owing to the higher acidity and unsuitable calcium to phosphorus ratio (less than 2:1), it’s best not to feed this fruit or its plant to your pet crested gecko.

What Can Kill Geckos Instantly?

Several factors and substances can cause the death of a crested gecko in an hour or less. Some things that can cause an instant or near-instant death of crested geckos are:

  • Bleach vapors
  • Very high temperatures
  • Very low humidity
  • A high content of persin being ingested
  • Periwinkle petals
  • Poison ivy
  • Phenols in pine or cedar shavings

Summary

As a crested gecko pet owner, you must be aware of all the possible things that are poisonous or toxic to your pet.

This will help you make informed decisions when it comes to creating a diet plan, maintaining the cleanliness of the enclosure and its surroundings, as well as maintaining a comfortable and safe enclosure for your crested gecko.

Certain toxins have mild or severe unpleasant symptoms like diarrhea and vomiting – and certain toxins can lead to the death of your pet.

So, it is important to be well informed about what is toxic to your pet – and find safer alternatives.
