Fruit Fly Bait & Spots, Solution & Insecticide
Protects mango
Fruit flies are controlled with spot applications of protein bait laced with insecticide, not full-cover sprays — flies feed and die. Get the bait spots, solution and insecticide for your area.
Fruit-fly bait mix
Next: place 20 bait spots and prepare 2 L of bait laced with 20 mL insecticide; refresh spots after rain.
Protein bait + a small insecticide dose lures and kills egg-laying females. Spot rates and bait choice vary by crop, fly species and trap pressure.

Bait the fly where it feeds, not the whole canopy
Fruit flies have to feed on protein before the females can lay, and that weakness is the key to controlling them. A few attractive spots of protein bait laced with insecticide, placed on shaded foliage, draw the flies in and kill them — including the egg-laying females that actually sting the fruit. Because you treat only small spots rather than blanket-spraying, you use a fraction of the chemical, spare pollinators and beneficials, and keep residue and cost down.
This tool gives the total bait spots, the bait solution and the insecticide to mix from your orchard area and spot spacing. Use it to plan a mango, guava, citrus or cucurbit baiting round, re-bait after rain, and coordinate area-wide treatment for far better results than one lone orchard. Pair it with the Pheromone Trap, Light Trap and Mating Disruption tools for an integrated fruit fly programme.

Frequently Asked Questions
What is fruit fly bait application?+
Fruit flies — mango, cucurbit and guava flies — are controlled with spot applications of a protein bait laced with insecticide rather than full-cover sprays. Flies are drawn to feed on the protein and are killed by the insecticide in it. This tool gives the bait spots, bait solution and insecticide for your area.
Why bait spots instead of a full-cover spray?+
Fruit flies must feed on protein to mature their eggs, so a few attractive bait spots per tree or per area kill far more flies per litre than blanket spraying the whole canopy. Spot baiting uses a fraction of the insecticide, spares beneficial insects and pollinators, and is cheaper and faster to apply.
How are the bait spots calculated?+
From your orchard area and the spacing between spots the tool works out how many bait spots you need, then multiplies by the bait solution per spot to give total solution, and applies the bait's insecticide rate to give the amount of insecticide to mix in. More, smaller spots generally beat a few large ones for catching flies.
What goes into the bait mixture?+
A protein source — hydrolysed protein or yeast autolysate — mixed with water and a small dose of a suitable insecticide, applied as coarse droplets or splashes onto foliage. Some growers use ready-made bait products; others mix their own. Follow the product label for the protein and insecticide rates in your region.
How is this different from pheromone or lure traps?+
Lure traps (such as cue-lure or methyl eugenol) mainly attract and monitor or mass-trap male flies. Protein bait attracts both males and females — including the egg-laying females that actually damage fruit — because both sexes feed on protein. Bait spraying and lure trapping work well together in a programme.
Where and when do I place the bait spots?+
Apply spots to shaded foliage where flies rest, away from direct sun and rain, starting before fruit becomes susceptible and repeating as the bait dries out or rain washes it off — often weekly. Area-wide application across a neighbourhood works far better than one isolated orchard, since flies move between hosts.
Does it work for any orchard or fruit fly?+
Yes — it works for mango, guava, citrus, cucurbits and other fruit fly hosts. Enter your area and chosen spot spacing, and use the bait and insecticide rates appropriate to your target fly and product label. The spots, solution and insecticide outputs scale to any block size.
How does baiting reduce chemical load?+
Because only small spots are treated rather than the whole canopy, spot baiting uses a tiny fraction of the insecticide of a cover spray, leaving fruit surfaces and beneficial insects largely untouched. That cuts cost, residue and resistance pressure while still knocking down the fly population feeding in the orchard.
Are the figures precise?+
They are solid planning figures. Real needs depend on fly pressure, rainfall washing off bait, canopy size and the product's label rates. Re-bait after rain, monitor with traps to track fly numbers, and follow the label — treat these numbers as a guide to mix and place the right amount, not an exact prescription.
