What You'll Learn
Australian house geckos are nocturnal hunters
The Asian house gecko, an invasive species in Australia, is also nocturnal. It was first introduced to the country in the 1960s through the accidental transport of goods and has since spread across the northern and eastern regions, including Darwin, Townsville, and Coffs Harbour. This species is highly adaptable and thrives in urban environments due to the abundance of food sources and sheltered spaces. They are often found on house walls and windows, hunting insects attracted to artificial lighting.
The Asian house gecko's diet consists mainly of small insects and spiders, but they are not picky eaters. They are known to consume a variety of food sources, including paper wasp larvae, other geckos, sap, nectar, and small invertebrates. Their varied diet contributes to their resilience and ability to adapt to different environments.
Native Australian geckos are also nocturnal hunters and can be found across various habitats in the country, including mountains, deserts, forests, shrublands, and coasts. They primarily feed on insects, such as cockroaches, spiders, and mosquitoes, making them welcome guests in many homes. Additionally, they may consume other invertebrates like earthworms and even small lizards.
The nocturnal hunting behaviour of both the invasive Asian house gecko and native Australian geckos plays a crucial role in controlling insect populations. Their ability to navigate and hunt in the dark effectively reduces the number of insects that can be pests or nuisances to humans.

They eat insects, spiders, and small invertebrates
Australian house geckos are primarily insectivores, and their diet consists of a variety of insects, spiders, and small invertebrates. They are skilled hunters, using their long, sticky tongues to catch prey. Their diet includes small insects like cockroaches, mosquitoes, and moths, attracted to artificial lighting in human habitations. This makes them effective pest controllers, reducing insect populations.
In addition to insects, Australian house geckos also consume spiders, which can include huge spiders like the Huntsman. They are known to eat other invertebrates, such as earthworms, and even small lizards or geckos. Their adaptability in diet and resilience as predators contribute to their success in various environments.
The Asian house gecko, in particular, has a varied diet, including insects, spiders, and other invertebrates. They are not picky eaters and will consume paper wasp larvae, sap, and nectar. Their ability to exploit diverse food sources enables them to thrive in different habitats, including urban settings, where they compete with native geckos for resources.
The impact of the Asian house gecko's feeding habits on the ecosystem is a concern for conservationists. Their presence can lead to a decline in native insect populations and competition with native geckos, disrupting the balance of ecosystems. These geckos have been observed eating native skinks and tackling the nests of stinging paper wasps, posing a potential threat to native species.
Overall, the Australian house geckos' diet of insects, spiders, and small invertebrates plays a crucial role in their survival and contributes to their ecological interactions within their habitats.

They are considered pests
Asian House Geckos are considered pests in Australia due to their impact on native gecko species and the broader ecosystem. They were first introduced to Australia unintentionally through the transportation of goods and have since established themselves in various urban and suburban areas. Their ability to thrive in human habitats is attributed to factors such as the availability of food sources, including insects attracted to artificial lighting, and the abundance of sheltered spaces.
Asian Geckos are highly adaptable and aggressive, competing with native geckos for resources and territory. They have been observed fighting with local geckos and displacing them from their habitats. This competition for resources has led to a decline in native gecko populations, disrupting the delicate balance of ecosystems and negatively impacting the food chain.
Additionally, Asian Geckos have a varied diet and are not picky eaters. They primarily feed on small insects and spiders, but they are also known to consume paper wasp larvae, nectar, honey, and even other geckos. Their broad diet can further impact the ecosystem, potentially causing declines in urban populations of some native insects and spiders.
Another reason why Asian Geckos are considered pests is their ability to damage electrical appliances and infrastructure. They have been known to chew on electrical wiring, short-circuiting electrical items, and causing issues with air conditioners and computers. This behaviour adds to the nuisance they can create inside residences, further contributing to their perception as pests.
The invasion of Asian House Geckos in Australia has raised concerns among conservationists and researchers, and measures are being implemented to address their spread and minimise their impact on native species and ecosystems.

They compete with native geckos for resources
The Asian House Gecko, also known as the Common House Gecko or Pacific House Gecko, is an invasive species in Australia. They were first introduced to the country accidentally in the 1960s through the transportation of goods and have since spread across various regions, including Queensland, the Northern Territory, New South Wales, and Western Australia.
One of the significant concerns regarding the Asian House Gecko's presence in Australia is their competition with native gecko species for resources and territory. They are highly adaptable and aggressive, which allows them to outcompete native geckos. This competition for resources has led to a decline in the populations of native geckos, raising concerns for their conservation.
Asian House Geckos have a varied diet, mainly consisting of small insects and spiders. They are skilled hunters, using their long, sticky tongues to catch prey. Their diet also includes other food sources such as sap, nectar, and small invertebrates. This adaptability in their feeding habits contributes to their success in various environments and makes them resilient predators.
Native Australian geckos, on the other hand, also primarily feed on insects and small invertebrates. They are nocturnal hunters, with eyes that are 350 times more sensitive than humans, aiding in their night-time hunting. They are known to consume insects such as cockroaches, spiders, and mosquitoes, making them welcome guests in many homes.
The competition for food resources between the invasive Asian House Gecko and native Australian geckos has disrupted the delicate balance of ecosystems. The Asian House Gecko's ability to outcompete native species for food has negatively impacted the food chain and led to concerns about the conservation of Australia's native gecko populations.

They are invasive and impact the ecosystem
Asian house geckos are considered one of the most successful invasive species in Australia. They were first discovered in Brisbane in 1983, having stowed away in shipping containers, and have since spread across the country. Their ability to thrive in urban settings can be attributed to factors such as the availability of food sources and the abundance of sheltered spaces.
The invasion of Asian house geckos in Australia has raised concerns among conservationists and researchers. These geckos compete with native species for resources and territory, leading to a decline in native gecko populations. This disruption can negatively impact the delicate balance of ecosystems and the food chain. The large number of Asian geckos and their feeding habits, which include insects, spiders, and even small invertebrates, can have broader impacts on the ecosystem.
Native Australian geckos have been observed to display aggression towards invasive Asian house geckos, suggesting that they will aggressively defend their resources when necessary. However, the tolerance of the invasive species for others in close proximity may contribute to its success. The invasive Asian house geckos have also been known to exhibit aggressive behaviour towards other species of geckos, often resulting in fights to establish dominance.
The spread of Asian house geckos in Australia has led to concerns about the conservation of native gecko species. Conservationists and researchers are retracing their steps to tally the number of Asian house geckos and measure their impact. While there is evidence that Asian geckos are outcompeting native geckos, the specific effects on native species are challenging to predict.
