Fly larvae predators

Biofly is a predatory fly also called Ophyra aenescens. Its predatory larvae consume the maggots of house flies and stable flies in the stables. They are harmless to animals and humans. Biofly is used in barns, equipped with a slurry pit or gratings.

How does it work

Biofly sachets contain pupae with beneficial flies ready to emerge. The bag can be hung in the barn or poured into a Biofly release station. After a few days the newly emerged adults will immediately head into the slurry pits to find their prey. The Biofly will then lay their eggs which will become predatory fly larvae capable of consuming up to 60 maggots during their life cycle. These predatory flies do not become invasive as they are limited by their amount of prey.

Biofly is a living product, composed of beneficial insects for biological control and can therefore be used in organic or conventional agriculture.

How to apply

Use a sachet of Biofly L for an area of ​​100 m² grid floor above a slurry pit. Make 3 releases at 15-day intervals in order to introduce predatory flies into the environment. Then renew a maintenance supply every 4 to 6 weeks depending on the pressure and emptying of the pits. The installation is very simple and consists of opening the bag, empty the content in the release station and hang it out of reach of the animals. As part of an integrated fly control system complete with Biomite predatory mites.
