Geckos are a familiar sight to most of us living in South East Queensland. At night, we see them scuttling across our walls and ceilings in pursuit of prey. These reptiles are a remarkably diverse group and have a broad distribution through tropical and warm temperate regions of the world.
The gecko that we most commonly see in our homes is the Asian Gecko, Hemidactylus frenatus. Also called the Common House Gecko or Pacific House Gecko.
Are Asian Geckos a pest?
They are the reptile we tend to see the most. Humans normally form a ‘love or hate’ relationship with our gravity defeating friends. Some regard them as a useful pest controller that eats spiders, moths and cockroaches for free. Others get annoyed with their chucking noise, droppings, shorting their air-conditioner unit and the unsettling appearance on the ceiling of a lizard directly above them.
How to control Asian geckos
For professional pest control companies in Australia, there are not a lot of options available to control geckos. There is no registered poison designed specifically for geckos. To confuse the matter, there are many urban myths and homemade cocktails to supposedly eradicate them. Eradication by direct application of these potions will not be the best long term approach.
By various methods listed below, you will be able to reduce the numbers of geckos. But you must understand that you will never completely eradicate them, overtime they will re-colonize from surrounding homes and find recently unoccupied harbourages around your home. It’s an ongoing battle.
- Get your home pest control at least every 12 months. If you reduce the availability of likely prey, you reduce the gecko population.
- Seal up cracks and holes where you see geckos. They too can be prey and normally hunt near a hole were they can scuttle into to escape. If they feel too vulnerable, they won’t hang around.
- Ensure there are insect screens on the windows you open at night. As we mentioned, moths are the most desired prey for Asian geckos.
- Turn off outdoor lights and pull the curtains. If there isn’t any lights to attract their prey at night, they will move on.
Second step – not for the fainthearted
- Glue boards and sticky cards, available through hardware stores or Coles & Woolworths, will catch and eventually kill geckos. Glue boards should be placed near lights and windows or outdoors surfaces where geckos prefer to congregate. Warning, glue traps are not for the soft-hearted, and does not kill the gecko quickly or allow for a humane release.
- Glue boards with a UV attractant light. The UV light will attract moths and other flying insects to the glue board. The captured moths will attract the geckos. We recommend to place a certain distance away from your home so the moths and geckos aren’t drawn near your place.
Some More Interesting info about the Asian Gecko
Being nocturnal, the Asian gecko loves to prey on moths, but being opportunist in its diet, it will dine on any insect that is slow enough to be captured. They tend to pounce rather than chase it’s prey. This is why you will see most of the geckos and their droppings near lights.
Asian geckos, as a lizard, don’t urinate. They only have a single opening for both the faeces and urine called the cloaca. You can easily identify gecko poo by a small white portion on their dropping, which urine expelled as uric acid.
Geckos don’t have eyelids. To keep their eyes moist, they lick them continuously with their tongue.
Geckos will drop their tails when a predator grabs hold. Obviously an escape ploy that comes at a cost. But they do have the ability to grow it back, but never the same colour or markings.
Asian geckos are noisy. Asian geckos are much louder and more talkative than natives geckos. Their “chuk-chuk-chuk” is aptly described as ‘scolding’ and usually their attempt to protect their territory. Native geckos tend to chatter softly.
Geckos have an amazing ability to walk vertically up walls and then across ceiling! I think it best you listen to Sir David Attenborough explanation in his BBC video.
