Possum repellents may work through two chemical senses: smell and taste. The list below has been suggested as options to try by wildlife Victoria.
Fish based fertilisers: Charlie Carp®
Tabasco sauce: use as a spray
Garlic spray: Place 2 tblsp of freshly crushed garlic in 1ltr of hot water. Allow to stand overnight. Spray on foliage.
Blood & Bone: Sprinkle around the base of your fruit salad tree.
A spray made from Quassia chips: add 100g chips to two litres of water and heat for one hour before straining. Add one tablespoon detergent. Dilute one part of the solution to four parts water and apply as a spray. Quassia chips are available at many nurseries, and are pretty effective, forming the base ingredient of many commercially available possum repellents.
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!
Just remember to follow all instructions on the packaging of any products you use.
It should be remembered that sometimes no one solution is guaranteed, and re-application of sprays should be a regular and on-going activity. Persistence is the key!
