Generally speaking, geckos are not poisonous. Geckos are common reptiles that belong to the order Lizards. They have the ability to adhere and can walk on vertical surfaces such as walls and ceilings. Geckos mainly feed on insects and other small invertebrates and are not directly harmful to humans. In some places, people often regard geckos as a symbol of good luck and are popular because of their ability to catch pests.

However, while geckos themselves are not poisonous, it is important to note that some geckos may carry bacteria or parasites, so personal hygiene should be observed when handling or handling geckos. If you are bitten by a gecko or experience discomfort such as redness and itching after touching a gecko, it is recommended to seek medical advice promptly.
