When to use Natupol Fly?

Natupol Fly or Lucilia sericata flies are used for small scale crops with just a few flowers or for crops that produce very little pollen. Examples of these crop families are: Cruciferae, Umbeliferae and Amaryllidaceae. For many seed producers, the flies are therefore the perfect complement to bumblebees and honeybees.

How it works

How it works

How does Natupol Fly work?

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.

Directions for use

  • The flies emerge over time, depending on the temperature.


  • Cruciferae: roughly: 20-25 ml of pupae per m², once a week
  • Compositae: roughly: 15-20 ml of pupae per m², once a week
  • Umbelliferae: roughly: 20-25 ml of pupae per m², once a week
  • Liliaceae: roughly: 20-25 ml of pupae per m², once a week
