It’s moth plant season and Council is asking everyone to help stop the spread of this highly invasive pest.
Moth plant is a noxious vine that smothers native vegetation and produces a sticky white sap that is toxic to many species, including bees, butterflies and even dogs. It’s a serious threat to the environment and biodiversity.
Council Biosecurity Team Leader Phillip Karaitiana says early action makes a big difference.
“Moth plant is one of the worst weeds we deal with because of how quickly it spreads and the damage it causes to native plants.
“If you see it, pull it out before it seeds. Every plant removed now prevents hundreds more from growing later.”
The best time to deal with moth plant is before pods form and seeds spread.
“If you spot a suspicious vine on your property, pull out the main stem and roots.
Hang the plant off the ground to dry, then dispose of it in your general waste bin.
If pods are already present, place them in a sealed bag and put them in your general waste.
Do not compost or dump them, as this will spread the problem,” says Mr Karaitiana.
Moth plant sap can irritate skin and eyes, so always wear gloves when handling the plant.
