How it works

How it works

Mode of action

When the flies emerge from the released pupae, they will lay eggs on or close to the manure, the developing larvae will predate on the house fly larvae. They can also develop on manure only. In contrast to the house flies Hydrotaea aenescens adults will not irritate the animals as they stay low in the pit.
