Gecko survey

Our 12 month community science project to map where people have spotted Asian House Geckos in their homes, was completed in July 2010. More than 4,000 people participated in the project.

Participants followed the identification key below to identify the difference between native geckos and Asian House geckos in their home.

Community results

The results show that Asian House Geckos have moved into people's homes. More than half the participants reported that Asian House Geckos have appeared in their home since 2005.

Some comments from participants include:

"They reduce the cockroach population"

"I enjoy watching geckos as I find them interesting with regard to their mobility, calls, territorial stance and their food requirements."

"Asian house geckos make a mess"

"They are not native to Australia and have become a very big problem like cane toads" Science for life!

Investigate geckos in your home

Have you seen geckos scampering through your house at night? Or heard their call? Do you think you can you identify an Asian House Gecko?

  1. Use the identification key and photos to compare and identify the geckos you see around your house.

Identification key

(from our Wildlife of Greater Brisbane, 2nd ed. 2007)

  • Geckos are readily identified by their soft velvety skin and large lidless eyes.
  • Most have expanded pads beneath their fingers and toes to assist climbing.
  • Geckos hide by day and emerge at night to hunt insects. They are most often seen feeding near outdoor lights.

Tips for living with Asian House Geckos around your home

Thanks to survey participants, we will be able to compare and see how far Asian House Geckos have spread. It is unlikely that their populations will decline, and so instead we can learn to adapt having them around.

Asian House Geckos eat insects and so are attracted to areas where insects gather – for example, around outdoor and indoor lights.

  • Ensure you switch off all unnecessary lights
  • Where possible, install insect screens on windows and doors
  • Use yellow light bulbs in outdoor lights as insects are not as attracted to these

Asian House Geckos like to live in warm areas – for example, behind electrical appliances such as air conditioners.

  • Ensure you switch off and unplug all electrical appliances when they are not in use

Using poisons around your home can be very dangerous for you, your children and pets.

  • Never use poisons to kill Asian House Geckos

Queensland Museum does not endorse harming Asian House Geckos or any other animal.
