Fruit Fly - Public Enemy No.1
Fruit fly products, other than the highly undesirable blanket spraying of a systemic chemical, generally are effective for either male or female flies, not both. The exception to this is the newly released Insectrap and Cera Trap, which are effective for both. Products that prevent female fruitflies from laying eggs are fundamental for achieving your aim of a luscious, ripe, home grown crop. Female flies are attracted to baits based on 'food attractants', as female flies need protein in order to begin egg laying. Bait products are most suitable for diverse gardens with a wide range of susceptible fruits or large orchards. The easiest 'set and forget' method is to install exclusion products early in the season.

The products that attract male flies are based on pheromones or 'sex attractants'. These include Qld Fruit Fly Trap and Wild May Fruit Fly Attractant. All are useful as monitoring tools, an effective 'early warning system' to help you recognize the start of the fruit fly season. Many gardeners will be familiar with the disappointment of only noticing fruit fly when it is too late and the fruit is stung and full of maggots. Traps for monitoring should be in place by late winter, in a position where they will be easily noticed. Many people find that by trapping large numbers of male flies, the local population of breeding fruit flies is reduced and that this helps reduce damage.

I have found that the Cera fruit fly trap system to be the only one I have ever seen work and be effective.

Cera Trap
For the attraction and mass trapping of Queensland (Qld) and Mediterranean (Med) male and female fruit fly in tree crops. Not recommended for tomatoes, use exclusion products instead.
This well-designed and proven product (throughout Australia, Spain, Israel and Mexico) is the best trapping system we've seen for these destructive pests in WA, VIC, QLD and NSW. 'Set and forget', convenient and safe. Ready to use - just open the jar, attach the lid and hang adjacent to your susceptible crop. It will work as long as the syrupy bait is in the trap, roughly 3-4 months. This is a mass trapping system, i.e. its effectiveness depends on having multiple traps around and throughout your crops.
The use of Cera traps alone may not adequately control fruit fly and additional control methods may be required. When fruit fly intensity is high e.g. the previous year's crop was heavily stung, the orchard is within 5 km of rainforest or it is a particularly highly susceptible crop (tomato, stone fruit, large mango, rows of vegetables) an additional product will need to be used. At the beginning of the fruit fly season a cover spray with a product containing pyrethrum or spinosad or a bait spray such as Naturalure will help to reduce fruit fly to more manageable numbers.
The female flies need a protein feed before they lay eggs in fruit, so it's important to place the protein-based Cera Traps near to where the females rest. They'll rest in mature fruit trees with lots of foliage but if trees are very young, deciduous or plants are relatively small the flies will be 'overnighting' elsewhere in the garden. So, you need a number of traps to catch them on their way to the fruit. Cera Traps contain no insecticide: the flies can't escape from the jar and drown in the liquid.

Material Safety Data Sheet

When to use: at least 60 days prior to fruit ripening, when fruit is small and still developing. Even earlier use should have better results by catching the juvenile male fly.
Where to hang: northern side of the plant; within the foliage or crop; 1.5 metres above the ground.
Quantity required: in a backyard situation, where trees are 5 metres or more apart, it is highly recommended you place 2 traps per tree, minimum.
Life of traps: unopened traps can be stored in a cool place for a long time. The ingredients are activated only when the trap is opened and exposed to oxygen. Traps can be moved to other ripening crops after harvesting and are viable while there is still liquid in the trap (average 3 - 4 months). The waxy-looking solids in the trap are normal and do not stop it working.
Advantage over other baits: you do not need to spray every 7 days; Cera traps catch the male (non-fruit damaging) and female; no poisons in your harvest nor handling of pesticide infused products; commercially successful around the world, where homemade baits are hit and miss.


The 5 litre Cera Trap bulk liquid can be used to re-fill the 600 ml container.
Cera Trap Empty Jars
This is an empty container, 600 ml plastic jar. Just fill with Cera bait and hang. Attractant not included.

Fruit Fly Trap (bottle only)
For trapping and monitoring Fruit Fly
  • Use a commercial liquid attractant bait e.g. Cera
  • You can make your own attractant bait if you prefer
  • Put out the traps early in the season and keep topped up until all the fruit is harvested
  • No poison required
  • The yellow top and the bait entice the fruit fly into the trap where it drowns
  • Can also be used with a different bait for house and bush flies
Fruition® Fruit Fly Trap
  • Set and forget (12 weeks) to catch all east coast fruit fly species.
  • attracts mature egg-laying (maggot producing), fruit destroying female Queensland fruit flies, Pumpkin fly and other native fruit damaging flies.
  • bait contains protein and fruit sugar attractants to lure females and males, thereby reducing breeding numbers.
  • mature and immature male and female fruit fly are attracted to the lure, the colour and shape of the trap and will stick to the glue covered sticky trap. This is the only trap system which catches all species and all sexes.
  • for optimal management of fruit fly populations, use traps for monitoring from the very early stages of fruit set, when fruit is still hard and green.
  • application: Set traps out of direct sunlight, within foliage where they receive dappled sunlight:
    • tree crops: hang in the fruit zone, usually 1.5 to 2 metres above the ground in the tree canopy in a location away from surrounding branches and clearly visible within the orchard to take full advantage of the attractant yellow colour. 1 trap per tree up to 3 m tall (mango, avocado, custard apple, unpruned stone fruit)
    • berry and vegetable crops: hang immediately above the crop canopy (around 0.5 metres), or in adjacent trees or vegetation within 5 metres of the crop where the traps can intercept mature egg-laying female fruit flies flying into the crop to lay eggs. 1 trap in an area of 10 m x 10 m
  • cage is made from recycled plastic and can be recycled
  • one pack contains 2 x traps plus male and female lures
  • each trap will last up to 12 weeks
  • Australian technology, Australian made and Australian owned; non-toxic and pesticide-free

Directions for use
This non-toxic, sticky, yellow, cylindrical trap attracts all fruit fly species, both male and female, via the food-grade feeding attractant which stimulates and guides them to the trap.
  • It is an excellent early detection and monitoring tool, especially for gardeners in TAS, SA and VIC new to fruit fly outbreaks
  • It gives multiple means to attract all Fruit Fly, with a bait, the shape of the trap and the yellow colour
  • In mild climates keep the traps in place year-round to catch and kill any early outbreaks
  • 2 traps for a tree up to 2 metres high or 4 traps for trees over 2 metres
  • Includes a mesh barrier to ensure that birds cannot touch the glue area and accidentally become stuck in the super-strong non-drying glue
  • The bait is effective for 3 - 4 months
Qld Fruit Fly Trap
New and Improved Trap Design
Fruit Fly Traps are used to monitor Queensland fruit fly; the plastic container includes a wick impregnated with a sex attractant combined with an insecticide (malathion) that kills on contact. Male flies are attracted from up to 500 metres away for up to 6 months.
(Not suitable for WA Mediterranean Fruit Fly)
