Cyantraniliprole is a relatively new active ingredient in fly control, and its main advantage is that it belongs to a completely different group from the insecticides flies have become used to. That is why it works well in places where flies no longer respond to older baits.
This article explains what cyantraniliprole is, how it works, where to use it, and how to fit it into a product rotation plan.
- Group: diamides (IRAC group 28).
- Mode of action: it affects the insect's muscles, so it stops feeding quickly and then dies.
- Form in fly control: ready-to-use granular bait with sugar and attractants.
- Main advantage: no cross-resistance with pyrethroids, neonicotinoids or organophosphates.
How does cyantraniliprole work?
The ingredient binds to receptors in insect muscle called ryanodine receptors, causing calcium to be released continuously from its stores inside the muscle. The result: the muscles contract and weaken, the fly quickly stops feeding and moving, and then dies.
This is different from how most fly insecticides work, which act on the nervous system. That is why flies resistant to other groups are still affected by this ingredient.
When do you need cyantraniliprole?
- When your usual baits no longer work, even though flies still visit them.
- In animal sheds and farms that have used fly insecticides for years.
- As part of a rotation programme, even without obvious resistance, to delay it.
How to use it
Where to place the bait
- Fly resting spots: sunny walls, window ledges, posts, near entrances.
- Around attraction sources: bin rooms, manure collection points, feed preparation areas.
- In dishes or bait stations so it does not scatter and children or animals cannot reach it.
Practical tips
- Spread the bait over several points instead of one large pile.
- Renew it if it becomes covered with dust or moisture.
- Do not put it inside feeders or on food.
- Keep to the quantity stated on the label.
How to fit it into a rotation programme
The idea is not to rely on one group all year. An example of a simple programme:
- First period: a bait from the neonicotinoid group (such as acetamiprid or dinotefuran).
- Second period: cyantraniliprole bait (group 28).
- Alongside both: treat larvae in breeding sites with a different ingredient such as cyromazine.
The length of each period depends on how severe the problem is. The key is to monitor: if fewer dead flies appear around the bait while flies are still present, it is time to switch.
Bait does not replace hygiene
- Manure and organic waste are the fly factory. Remove or cover them regularly.
- Close bins and clean around them.
- Cut moisture where waste collects.
Safety
- Wear gloves when handling the bait.
- Store the pack in a locked place away from food and feed.
- Do not place it near beehives or flowers.

Frequently asked questions
Do flies die immediately?
The fly stops feeding and moving quickly after eating, and death follows. That is why you may see dead flies both around the bait and further away.
Can it be used inside the house?
Granular bait fits best outside the house: yards, animal sheds and bin rooms. Indoors, traps and hygiene are enough.
Should I use it all year?
Better not. Use it within a rotation programme with other groups so it stays effective for years.
What is the difference between it and cyromazine?
Cyantraniliprole is a bait that kills adult flies, and cyromazine works on larvae in breeding sites. The two complement each other.
