According to the Department of Sustainability and Environment, it is not permissible to keep wild-caught specimens. However, you can create a frog-friendly garden and attract more of them to your yard, using the tips given on this website.

I am having a major issue with brown tree frogs whilsting during the evening and late night. Can you please provide some insight in how to deter these frogs away from my pool and backyard. My neighbours & myself have had to many sleepless nights. Recently I have been cutting tree branches down in my backyard & have been leaving them to dry out before removing. I think this might create a habitat for the frogs.

Keeping frogs away from a habitat they enjoy is challenging, especially when the frogs are as adaptable as these ones. As noted in the above article, it's not only watery environments that attract these frogs - a range of features of your yard may be "frog-friendly" ones. For further information about garden features that attract frogs, see the link provided in response to Mitchell's comment; might reversing some of these suggestions help?

I have seven Brown Tree Frogs that have formed from tadpoles what can i feed them and do they need a heat lamp?

Hi Brandon and thanks for your query. Brown Tree Frogs are predators and will begin feeding several days after metamorphosing and leaving the water. They will eat small insects (small enough for them to get in their mouths whole). Small crickets and cockroaches (commercially available) are ideal, but they can be fed wild caught insect such as flies and moths. Avoid feeding them stinging or biting species such as wasps or ants.  Please note: Although Brown Tree Frogs are a common local species, they are protected by law. Any frog kept in Victoria must be obtained from a legal source (breeder, pet shop, etc) and cannot be taken from the wild.

Hi Brandon.  Thanks for the further questions about your frogs.  We have again asked our Live Exhibits team for information for you.  Your frogs do also require ‘land’ are within the tank. A substrate of moist coco-peat, available from a hardware store, is suitable. The substrate will need to be changed periodically to prevent the build up of wastes. And you can expect your Brown Tree Frogs will grow to between 25 – 40mm.

i had no idea that brown tree frogs were in victria as i thought it was only the tropics. i had one in my shower recess it jumped onto the back of the bathroom door with its little suction caps then jumped onto my arm. i put it into my fernery where there is shelter and is moist. it didnt look like the striped one illustrated in the picture it was just a plain brown colour.

Hi, I think there is a/some Litoria ewingii in my yard after the hail storm yesterday (my backyard is flooded out) but its night and I cant see. I listened to the call and it was the same as the Litoria ewingii. Could these frogs pose a threat to my pets? I have two dogs. Also how can I move them safely? Is there a service to remove them?
reply

Jo, these frogs pose no threat to dogs whatsoever, and will probably disappear along with the floods. Please do not attempt to remove them in the meantime, as this is highly disruptive to the frog population. See this website for further info. Hope this helps!

We have caught a southern brown tree frog that our dog was trying to get. We can't let it go in our yard as the dog will just try to attack it again but we are very attached to him and are afraid to let him go in any of the places we know of as there are ferral cats that might eat him. We live in Tasmania and I am wondering if there is anywhere we could contact to help us with information on the safest place to let him go.

Hi Megan - thanks for your query. We recommend you contact the Tasmanian Parks and Wildlife Service for advice on releasing your Brown Tree Frog into the wild.

Just caught what I think is a Tyler's tree frog in my shower recess. We have no pond, a dog in the backyard and both neighbours have dogs, so we have no idea where to let it go. Would appreciate some advice. Meanwhile, we've put it in an old fish tank with some water in it to moisten its skin. Thank you.

Discovery Centre 30 Mar 2010 09:59

Hi Ping, we have contacted the Live Exhibits team for some advice for you.  As the frog has made its way into your house, there must be a suitable frog habitat somewhere nearby, perhaps a parkland or wetlands. Our Live Exhibits staff have suggested that such a habitat must be somewhere close to where you live.

Hi, we are getting what I think are brown tree frogs in our bathroom. We've had about 10 in the last few weeks. I don't mind them getting in there but the problem is they collect up all the fluff and hair off the floor onto their bodies, and if I don't see them in time to free them, they die. Do you have any ideas how they might be getting in and what to do to discourage them from coming in the house? One side of our garden is very nice and damp and we do have frogs living in there as I hear them at night, so I'm not sure why they'd be wanting to come inside! Thanks. :)

Hi, a friend of mine who lives in Torquay Victoria gave me two cuttings of Staghorn or Elkhorn Ferns. When I opened the green synthetic bag in Dandenong Victoria to take them out a Brown Tree Frog jumped out at me and landed on my chair and then jumped away but because I know there are no frogs in my area I caught him and put him in my carnivorious plant terrarium. Even though he can jump onto plants he just stays in the water. I need to know what I should do with him as my flat mate wants to flush him and I fear for his safety if I don't do something soon.

Hi Ruben, we have contacted the Live Exhibits Team and they have suggested you consider one of two things.  You could either return the frog to Torquay or alternatively contact the Lost Frogs Home, you can find details here: http://frogs.org.au/vfg/features/lostfrogs.html

i have 10 brown tree frogs all bought from the pet shop my tank is totally set up for breeding and i think one of my frogs has eggs in her belly she has got really fat all of a sudden and belly has gotten very dark but she wont lay! there is plenty of water and reeds and rocks and plants and water temp is perfect. just wondering what else i can do to encourage her to lay as i dont want her getting sick or her babies not surviving.... chloe

Hi Chloe - Your frog requires a mature male to grip her in amplexus before she will release the eggs, this usually occurs after the male has been calling. Hopefully you have a mature male or two in your enclosure. Increase the amount of mist spraying (rain) the frogs are getting, this may stimulate males to call and things to happen.

chloe 24 Jun 2010 00:06
thanks for that info, i think i have at least 2 calling males in the tank so ill start sraying tonight! they always call around midnight for some reason too, is this the time that it should "rain"?? chloe

Hello Chloe, We suggest you contact the Amphibian Research Centre regarding your frog eggs. This centre has a useful email contact address and website with an information page ‘A guide to Keeping Tadpoles’. Good luck. We hope the eggs are fertile.

Hi Taz, it's great that you are concerned for the frog but our Live Exhibits staff have said that the best thing you can do for the frog is release it. Keeping it in captivity increases the disease risks.

Hi Dion, the weekend weather was perfect for frogs, it was warm and damp.  The frog would be coming to the light to look for insects.

If you find 1 Brown frog around you`r property after it`s been raining,Do that mean there`s more frogs not just one?,Like what i mean is...Do they live with heaps of other ones too,Or i`m just lucky too see one and that`s it?,Cos i like too attract em too my pond.Thanks Dave from S.A

Hi Dave,

Usually one frog would mean that there are probably more in the area. Brown Tree Frogs (Litoria ewingii) breed in the winter months (June-Sept), so that is the best time to see and hear them, as they will come to small water bodies to breed.

Hi, Yesterday I found a 2.5 inch brown (striped) frog in a disused icecream container full of water. The container is sitting on concrete under a potted fiscus tree in the backyard. Should I leave the frog there or should I try and relocate it to the Editvale/Chelsea Wet lands where it may have come from? If relocation is the answer then should I put it in the water or just the grasslands?

I found a brown tree frog hoppin infront of my garage about a week ago. i tried to keep him (he was very very very tiny) so i went to the pet store and got some coco nut dirt stuff and some flightless fruit flies i had him in a container overnight and someone must have closed it overnight cause he died. anyways the same exact thing happened today. my question is is that do i feed him the flightless flies in his habitat or take him out into a container and feed him there? mind u his container is only about 3.5-4 in. wide and about 7 inches tall and i put a divider in there so all the coco nut stuff didnt get nasty. so do i take him out or just put the flies in that little container?

Unfortunately you should not keep your visitor as a pet. The Department of Sustainability and the Environment (DSE) states that it is not permissible to take frogs from the wild, or to keep native animals as pets without the correct licence. Some native animals can be kept as pets provided they are sourced from licenced breder. A list of the native species that may be kept by private collectors can be found at on DSE Private Wildlife Licences website.

Hi, I believe I have a bunch of these guys in tadpole form in my rain barrel, I live in a share house that is planned to be demolished in two months time and was wondering, how long it would take for them to grow into a form that will allow them to survive? If they wont grow in time I do have another option, there is a park nearby with a massive pond, If they wont be able to grow in time here I could possibly pour out my rain barrel into the pond. I know many will not survive because of fish and other predators, but I think it is better than just killing them outright. It's a minor annoyance as I use this water for gardening, but I'm not about to kill a bunch of baby frogs & I have other water sources anyway. Any help you could give in this situation would be grand. Thanks, Roben

Hi Robin,

We forwarded your question to Museum Victoria's animal keepers, who responded with the following:

Brown Tree Frogs (Litoria ewingi) have one of the shortest periods as tadpoles of all Australian frog species – coincidentally, about two months. This will vary on the ambient temperature and water temperature, as well as the availability of food, but means that they should have metamorphosed by the time the house is demolished. If they are still tadpoles at that time, they will at least have grown and become more robust in the intervening period, so if you need to transfer them they will have a better chance of surviving in a new habitat.

Hi We have some Tasmanian Brown Tree froglets at the Kindy where i work, some of them have only become frogs a few weeks ago and some only a few days ago. My question is should we be keeping them in separate environments? Also once the tadpoles are sitting on the 'land' in their enclosure, can we move them directly into the frog enclosure? Thanx
reply
Discovery Centre 29 Jan 2012 16:37
Museum Victoria

Hi Claire, the species you have is most likely the Southern Brown Tree Frog (Litoria ewingi). They can be kept together as a group when adults, so there is no need to separate them. Once the tadpoles have left the water they have less need to return to it, but water should be provided at all times for the adults as well. The adults have little need for water compared to other frog species, but should always be given access to some, even if it is a small water dish. In your situation you might as well keep the metamorphs in an area with water, just in case they feel the need for it.
