Living with possums isn’t always easy, but there are a few things we can all do to live in harmony with possums in our shared urban spaces. Let’s face it… we are never going to get rid of them all together, and why should we? They were here long before we were, and it is our destruction of their habitat that has forced them into our houses, our gardens, and lives. So, what steps can we take to make sure we can all get along together?

Possums in the roof?

There is one reason that possums will shift in to our roof spaces… lack of hollows in their habitat. You see, Common Brushtail possums utilise tree hollows for resting and nesting during the day, and are pretty happy to do so. But, the removal of remnant trees in urban areas has severely diminished the number of hollows available, and thus, we end up sharing our houses with them. So, what can we do to help them… and us? If you currently have possums in the roof, here are a couple of tips that should encourage them back into the wild:

1. Make or buy a suitable nest box for the Common Brushtail possum, and install it in your garden to act as an alternate den site for our furry friends. For more info on nest boxes, check out www.baag.com.au for more info.

2. Locate the nest the possum has built in your roof, remove it (when the possum is out and foraging) and place this inside the nest box. This will encourage the possum to move to its new location.

3. Place a piece of fruit inside the nest box. Apple or bananas seem to work best. This will entice the possum to investigate the nest box, and hopefully decide to stay. It should be stressed that feeding of possums is not recommended (except as a one off during relocation).

4. Block of access to your roof. This can be done by loping any overhanging branches, and placing collars around the trunks of trees that possums utilise to access the roof. Collars can be made from a number of products, but 60cm wide sheet iron seems to work pretty well.

5. Place camphor blocks OR mothballs in the roof space, particularly around the area where the nest site was. DON”T place both! Possums really dislike these smells, and will be reluctant to return.

6. If possible, pop a light up in the roof space, and leave it there for a few days (on of course!). The combination of alternate nesting site, bad smells and light should be sufficient to discourage them.

7. Once you are satisfied that the possum has left the building, block any known entrance points. Wiping around the entrance points with household bleach will remove possum scent, and make re-entry pretty unappealing!

Possums eating your plants?

Even the most patient and wildlife friendly gardeners tear their hair out over this one, but, after significant research, I can tell you that there are solutions to stop your precious plants being gobbled by hungry possums! Possum repellents work by two methods: taste and smell! Research conducted has shown that smell deterrents are somewhat more effective than taste, but also suggests that a starving possum will eat just about anything! So, here is a list of some tried and true methods of deterring possums.

1. Net affected plants with shade cloth or white bird netting at night time. Quick, cheap, and darn effective! This is absolutely the best way to protect young plants and seedlings from possum attack. Why not supplement this with a hanging cat scare face or two? Available from nurseries, these scare faces look like cats and have reflective eyes, pretty scary if you are a possum!

2. Sprinkling blood and bone fertiliser around the base of ornamental plants and fruit trees can act as a significant possum deterrent. They hate the smell, and will be less inclined to munch on treated plants!

3. A home made garlic spray of 2 tablespoons of crushed garlic in one litre of hot water, left to stand over night, strained and sprayed onto foliage, fruits and tasty growing tips is an old favourite of mine, and it seems to work. Subsequently, try chillies or Indonesian fish sauce. Just remember to wash your produce before eating!

4. A spray made from Quassia chips (chips of bark from a South American tree). Add 100 g chips to 2 litres water and heat for one hour before straining. Add one tablespoon detergent. Dilute at rate of 1 part of solution to four parts water and apply as a spray. Quassia chips are available at many nurseries, and are pretty affective, forming the base ingredient of many commercially available possum repellents (e.g.: Poss-Off).

5. My grandmothers’ personal favourite, and one she swears by, is the tea-based deterrent. Boil two litres of water; add 4 heaped teaspoons of Lapsang Souchong tea and leave to cool. Strain of liquid and apply from a plastic spray bottle directly onto affected plants. Reapply every two weeks and always after rain. Make a fresh brew every time.

6. Wack a bit of undiluted Tabasco sauce on affected plants……a sure solution unless your possum likes it hot!

7. A watered down solution of a little detergent and some English mustard sprayed directly onto the foliage and fruits of tasty plants.

8. Commercially available possum deterrents such as Poss-Off or Scat, work by emitting an unpleasant odour, so, when used according to the instructions on the products, claim to deter the little blighters!

It should be remembered that no one solution is guaranteed, and reapplication of sprays should be a regular and on-going activity. It is recommended that most sprays be re-applied every two to three weeks, and after rain. Try using these repellent sprays along “possum highways” as well (e.g.: tops of fences, well used tree branches). As possums are creatures of habit, any disruption to there regular routine can be really upsetting, and will often result in the possum moving away to seek a feed elsewhere.

Persistence is the key! A habit (as we all know) is not broken in a day, so keep up the spraying, re-apply, and over time the undesirable behaviour should dissipate. Good luck!

  1. Just read through all the tips on stopping possums eating your trees as we have a resident mother and baby who strips most anything. We live on over 2000 acres and have a large orchard that doesn’t seem to suffer from over possum use. When we moved in here the possum lived on the hot water system at the house we have being successful in moving it away from the house but it regularly comes back to see what is new to eat. I have found the only way is to put my garden behind an electric fence made for chickens. It comes in 50m lengths. It not only keeps out the possum but also the wallabies and other little furry creatures. This way I get to grow produce for my family and not have to cover everything with wire or spray stuff which I would be bound to forget. I don’t know if this is a viable option for city living I guess it depends on how much room you have, Hope this helps someone.

  2. we have about three or four brush tail possums come every night, we feed them apples and any left overripe fruit but sometimes they still eat my plants, I cover them with those mesh food covers which usually works. We also have a couple of ring tails who live in nests in our front garden, I also feed them. I was a little disappointed this morning as the brush tails have eaten all the flowers and leaves off my new petunia which is in a hanging basket, didn’t think they could get to it but they did. I will trim the petunia and tonight cover it with mesh, hopefully it will recover.

  3. Anyone got any suggestions on how to stop brushtail possums eating our liquid amber tree? Every year they decimate all the new growth night after night by feasting and gorging themselves on the new leaf shutes before they have a chance to open. The tree is dying more and more each year that goes by as a result. HELP!!

    • You could try spraying the tree with something bitter like Quassia solution (made by boiling Quassia bark) or even good old fashioned Bordeaux. If the tree is larger a metal collar about 600mm wide fitted around the trunk would deny them access to the tree from the ground. Providing ‘sacrificial’ food such as apples may also help but may be expensive if there are a number of possums. Seconds and throw outs from fruit shops may help.

  4. I’ve tried all of the above deterrents but none seem to work at all. Our resident possum family have taken to liking garlic, chilli and actually seem to relish it! Last year most of my peach and plum blossoms vanished overnight and I was pretty devastated.

    Then I got this idea from one of the forums. The ONLY thing that works really well for me making sure the possums are fed their favourite meal every night. I have set up two feed stations sitting on the fence on either side of my backyard. I divide 1 and a 1/2 thinly sliced apples (get them a 1-2$/kg at the farmers market) equally and leave them for the possums. I do this only when trees are filled with blossoms and when fruits are beginning to ripen until I harvest. Once the possums have eaten the apples they just leave my garden alone. Do give it a try.

    • This approach seems suitable – our article suggests a similar method of placing fruit in a nest box well away from the trees they are targetting.

  5. “And it is our destruction of their habitat that has forced them into our houses, our gardens, and lives”. I would suggest the reason they are so prolific is the abundance of food around our homes and farms has caused the populations to explode. If you travel to undisturbed bush you will see that their numbers are miniscule compared to the urban and rural environment. It’s a pity we don’t have the same attitude as NZ to possums.

  6. Thanks Bec (5/7/2017)
    I have planted a Lilly Pilly exactly for that reason. Our local possum loves it and appeared to be quite happy munching on the new leaves that sprung up .

    However, we may have an intruder because our beautiful potted Dipladenias of 10 years have been totally annihilated in the past 3 weeks. I am watching them disappear before my eyes.

    I didn’t think Possums liked this plant????

    Does anyone know if they do or are we grappling with a different species altogether?

    Karen

    • I think your Dipladenias are being munched on by the same uninvited guests looking for a bit of variety. The article on this site has a number of useful deterrents. I have known of the one using Quassia chips for nearly 50 years. Making your plants unpalatable is the best way to go. Relocation of the offender to another location is an option.

  7. A tale of woe… I was just showing our electrician the wonderful garden bench my husband made on the week end. Complete with chicken wire, everywhere EXCEPT where the chilli plants were. This morning they are sticks. All the foliage and flowers gone….. a hot tasty feast for our possum and a lesson learned.
    Possums do eat Chilli plants!

  8. We have a bit of a possum problem but I can’t find any answers to solve it ! We have recently moved into a new home but there is a little possum who lives here to but he’s a little friendly and comes very close to you .. so no matter what if we leave the security light on he doesn’t leave ? But my problem is his upsetting my little dog and he sits up on the back deck watching my dog while my dog barks at him the possum doesn’t have a care in the world

    • Hello Tahnee. It seems like a possum/dog reconciliation problem! Small dogs are often fairly feisty when they feel threatened. If the possum is not causing any other problems is it possible to talk to a vet or dog club for some tips. The other alternative is to get the possum trapped and relocated to another

      • In SA they don’t trap and relocate very often otherwise you are moving the possums out of their territory causing fights in the new territory. This lady’s problem to me is that the previous owner must have lived quite successfully with the possum and it is used to having food left for it and is used to being around the previous owner as it sounds quite at home in its territory. They have about 3 yr life span, if yours is an adult that reduces the time again. Stopping other possums when your dies will be important as others may move in to take the territory. Perhaps bring the dog in side at night and out during the day may help with the problem. Good luck.

  9. I have found screen door mesh put over selected plants at night to be the best solution. The holes are so small they can’t eat through it. It’s stiff enough that it’s quite easy to throw over and it does not catch on the plants. If you need it to be wider just staple (office stapler) strip’s of it together. I use ordinary household pegs to hold it onto plants if needed.
    I have wallabies coming in as well – and they DO eat everything! But it seems to deter them as well.
    Its also not quite as unsightly as the large holed white bird netting so give it a try. I get it at bunnings and you can buy it by the metre for very little cost.

    • Lynne, that is a wonderful suggestion! Thank you. I think hardware stores will now notice an increase in screen door mesh sales!

    • Lynne, they eat my Asian water spinach. It grows really easily. I live on Bris Nth side too if you want some cuttings, cheers Heather

  10. I’m actually looking for information on plants to grow to feed possums – especially ringtails. All I can find is humans complaining about our native animals eating their natural food source. It is very disheartening.

    • Yes, most of the information on the internet is about getting rid of possums, but it is good to hear of someone who wants to nurture our native animals. You might find http://www.naturalresources.sa.gov.au/files/…/sharing-the-garden-with-possums-fact.pdf
      helpful.

      • That link doesn’t work.
        I agree. I’m actually looking to see what they do and don’t eat. They leave apple and parsley if I leave it out for them. So far they haven’t touched the passionfruit vine.
        Ros. They’re classed as a ‘folivore’ and from experience they like mint, parsley and any of those european herbs. They cleaned out my mango tree. So fruit and anything leafy is my guess.

        • Sorry, they EAT apple and parsley, not leave as I incorrectly wrote in the last comment.

    • Hi Ros,
      I’m on the Northern Beaches near Sydney, and my 22 year old mango tree is completely devastated by the “ring tails” that feed on it every night. In the 2 decades I’ve grown this, I’ve only had one decent harvest or about 24 mangoes, and that was about 18 years ago!
      Basically nothing since, despite the full blossoming, and new shoots. The “ring tails” strip it bare weekly.
      If you want ring tails, plant a mango tree!

    • I completely agree with you Jenny. I have possums in my garden, and they are very cute and harmless. The fruit I want to keep have a net over it. It is sad that all my attempts to make them a home end up as a shelter for bees as they hurt the possums to take their house. I might have to put a cat door on the next box. I am going to plant them some more food as well. Love sharing my garden with them.

    • Sadly, so true! I am trying to find the same information to support the local possums in my area of north Brisbane. It’s tragic that so many see them as a pest. They were here first! We keep pushing them out and destroying their habitat.

    • I would recommend planting Syzygium (sorry not sure of spelling)
      Lilly pilly – they love it!
      I would advise against encouraging possums toward an unnatural diet – Fighting and in turn possum dermatitis (especially amongst brushtails) can become a big problem if many are gathering around 1 food source

  11. There was a scientific study on the effectiveness of these and other deterrents (http://www.depi.vic.gov.au/environment-and-wildlife/wildlife/problems-with-wildlife/possums/possum-repellents), the results suggest that when possums are hungry, no smell/taste deterrents stop them.

    In my experience, I have used a home made spray made with powdered garlic and boiled down habanero chillies, I needed a mask to apply it, and it failed. Blood and bone also failed to stop the possums. I have also bought the extruded netting (white plastic netting) from Bunnings, and the possums can just eat straight through it.

    The only definite solution is chicken wire or other strong netting (READ: metal reinforced netting).

    Such a shame that these natives (now pests) prevent so many urban gardeners in Melbourne from being self-sufficient as it is illegal to humanely remove possums.
