Teaspoon of Vegimite
Step 1: Cut Two Holes in Ur Bottle
Then one of the otherside.
Step 2: Fill Ur Bottle
Leave to cool.
The only thing that attacts more flies and for longer is the fly lure from www.wildmay.com, just found vegimite is more easily accessable, but if your really keen to kill most of the local fruit fly population, i'd really recommend trying this!
See attached picture
P.s. Eventually the Fruit flies lose interest in a week or so thats when its time to empty the dead flies and refill the bottles. Guess the dead flies scare em...
Step 3: Hang It Near Your Fruit Trees
Then tie the string which makes a loop or tie it to the tree.
Step 4: Catch the Flies
No Pesticide on your fruit or plants is necessary!
And watch the flies enter and drown..
Here's a picture of what a few second later looked like for me.
Occasionally refill, and get rid of dead flies..
They recommend 4 traps per hectare, but i have 6 around a townhouse garden..
