How it works

How it works

Mode of action

The flies search for nectar in the flower and thus come into contact with pollen. These pollen are not consumed by the flies but stick to their bodies. When a fly visits another flower the pollen are transferred to the pistils of the flower which is needed for pollination.

Product specifications


Cardboard tube which contains 1 kg pupae, from which approx. 30,000 flies emerge.

Directions for use

Directions for use


  • Put the required amount of pupae in a cup
  • Place the cup in the crop on the soil. Do not scatter the pupae in the crop
  • Protect the pupae from direct sunlight and moisture such as rain or condensation
  • The flies emerge over time, depending on the temperature
  • If outdoor temperature is below 18°C it is best to keep the pupae indoors at a temperature of 20-25°C untill the first flies start to hatch. Pupae can then be released in the crop


Adjust the quantity in relation to the number of flowers per m². As a general rule apply for Crucifer, Umbellifer and Lily crops 20-25 ml of pupae per m², once a week and for Composite crops 15-20 ml of pupae per m², once a week.

Environmental conditions

Natupol Fly performs best at ambient temperatures between 18-28°C.
