Did You Know? 15 Incredible Common House Gecko Facts

Read these interesting common house gecko facts about these reptiles with a prehensile tongue

The common house gecko, or Asian house gecko, is a species of gecko found in southeast Asia, Africa, Australia, and America. Unlike other species, they are more aggressive and might attack other geckos if they enter their territory. They are called an invasive species, which means that they are harmful to the environment and their surroundings. Despite this, they are kept as a pet by many people.

Cannibalism has also been spotted in these geckos as there have been reports of adults feeding on smaller geckos, mainly juveniles in their native areas. As they are an invasive species, they do not get along with other species of geckos like the robust velvet gecko. They are often mistaken as Mediterranean house geckos (Hemidactylus turcicus).

They can grow to a length of 2.95-5.91 in (7.5–15 cm) and have an average lifespan of about five years. They are not harmful to humans and are not venomous. They may sometimes bite if they feel threatened. As the name suggests, they have a strong preference for houses and urban environments. They emerge out in the nights and get back to hiding in the early mornings.

How to get rid of common house geckos?

Many people do not like the presence of common house geckos in their homes. There are various remedies to get rid of them. Gecko house lizards cannot tolerate the smell of onion or garlic, so you can place some in corners or use things such as a small table fan to spread its smell. You can use naphthalene balls as they drive lizards and other bugs crazy, but you have to be cautious as they are hazardous and should be kept out of reach of children. You should clean cabinets regularly, especially under the sink, and try to keep them dry using newspaper as geckos prefer humid areas and can come if it becomes humid.

Apart from the smell of onions or garlic, they also hate the smell of eggshells, so you can place eggshells in your house to keep them away.

Do not keep exposed food or leftovers in the house. Leftovers are one of their favorite things and also helps them to breed. Open food attracts flies and other bugs, which attract lizards. So, in order to keep unwanted flies and bugs, and geckos, out of your house, you should always get rid of exposed food.

Can common house geckos be pets?

Common house geckos can be kept as pets, but they require a lot of care. They require housing space, and for them, a medium-sized terrarium is enough. Males are aggressive, and so you should keep only one in a tank. On the other hand, females are less aggressive, and two can be kept in a tank, but they also need separate spaces.

They need a humid environment and adequate temperature. 75-90 F (23-32 C) during the daytime and during the night it should be 65-75 F (18-23 C). You can also use a red bulb to provide heat during the night.

They also need to be provided calcium supplements two or three times a week and multi-vitamins once a week. Crickets are a significant portion of their diet. You can powder these supplements on cricket or worms to feed them. Adults can be fed every day, but juveniles need their food daily. You can spray water on plants for water, and the droplets remaining after mist work as a source of water for them.

The water and their droppings should be cleaned daily, and the tank requires cleaning once a week. The tank should be rinsed and scrubbed thoroughly so that no odors remain.
