The splash-bait method of fruit fly control is used on most species in area eradication programs for fruit fly, and in commercial orchards, especially citrus orchards.  A protein source is mixed with an insecticide such as Maldison in water, and splashed onto fruit tree foliage in small quantities (approx 100 mL per tree), avoiding the fruit.  This method does not introduce systemic insecticide into the tree and hence the fruit, and is favoured by those worried about pesticide residues, and those using some forms of Integrated Pest Management (most beneficial insects remain undisturbed).  Its drawbacks are the frequency of applications throughout the fruit season, and it is not as effective as, say, fenthion or dimethoate, under severe pest pressure or frequent rain.
Dakpot Fruit Fly Attractant is designed to provide the protein component of a splash-bait for the average gardener’s full season of applications.  The protein is processed to have a much lower salt content than protein hydrolysate, and so causes  far less burn on delicate varieties. The bottle suggests suitable insecticide components and quantities for mixing with the protein to make splash-bait. Since the bait is an attractant, patches of it will draw the fly to it, so cover spraying is wasteful and unnecessary.

Male Queensland Fruit Fly are attracted to the trap by an odour associated with mating, sometimes from some hundreds of metres. On entering the trap they feed on a para-pheromone and an insecticide, and fall to the bottom of the canister where they can be counted.  Regular (preferably daily) inspection is recommended in order to detect and so check an infestation before significant damage can occur. Normal observation of fruit for stings should still be practised.
As with all traps that attract only the male fruit fly, Dak•pot traps cannot be considered to be adequate as control measures themselves. They should be used in conjunction with cover sprays or splash-baits as required by the various Australian state agricultural authorities.

What fruits are affected by Queensland Fruit Fly?
Fruit flies lay eggs in all fruit (except pineapples) including tomatoes, fruits of flowering peaches and other fruit bearing ornamentals.
When are the fruits most susceptible?
Queensland Fruit Flies lay eggs in maturing and ripe fruit, not in blossoms or very young fruit.
What area does a trap cover?
Typically, 2 canisters should cover a residential block.  In orchards and market gardens where routine spraying of insecticide occurs, lower densities might be used, depending on crop susceptibility  e.g.. 3 per ha. in apple orchards if placed in a suitable grid with extra units outside the crop boundary.
How many flies indicate a problem?
Any consistent catch indicates a problem.
Should the trap smell?
The lure is not often obvious to humans .. but fruit flies can detect it from up to 500 metres away.
What is the useful life of one of these traps?
One season.  Replace each spring or when a new unit placed nearby catches significantly more flies.  Traps should be left out all year round to reduce the breeding population of males.
