Frequently Asked Questions

Does the parasitoid pose a threat to humans or livestock?

No. It feeds on fly pupae and reproduce in the fly pupae. Normally they go unnoticed.

What fly species are targeted?

A number of species, including the housefly and stable fly, which causes the biggest problems in stock farming situations.

Why a regular release programme?

Flies breed much faster than parasitoids. For effective suppresion of flies it is important that parasitoid numbers are regularly boosted in a release program.

How long before flies are controlled?

The moment the parasitoids are released, they should seek out fly purpae to feed on and lay their eggs in. The effect may however, not be immediately visible. With follow up releases and the emergence of own off spring, adult fly numbers will gradually decline. With proper application, significant results should be visible within three months.

What are the requirements for success?

- Take enough parasitoids and release them as close as possible to active fly breeding areas.

- Take care to identify all fly breeding areas. On smallholdings better results are obtained where neighbours work together.

- Control adult flies, but keep chemicals away from parasitoids on fly breeding sites.

NB* TAKE PROPER CARE OF YOUR PARASITOIDS, THEY ARE LIVING CREATURES. FOR INSTANCE, EXCESSIVE HEAT IN CLOSED VEHICLES WILL KILL THEM EVEN IN THE PUPAL PHASE!
