Bye-o-Fly® E

The natural predator of fly eggs

What is it?

Bye-o-Fly E (Macrocheles robustulus)  is a beneficial insect, a predatory which attacks the eggs and larvae of various Diptera spieces, particularly flies and gnats.

The adult predator measures 0.6 to 0.8 mm, has a beige-brown color with a white border. The juveniles are white-cream and all stages are predatory.

The species is native to Europe and is found naturally in many habitats. 

How does it work?

Once installed the predators prey on eggs and very young larvae of different species of flies and also eat the eggs and young larvae of flies such as fruit flies or fungus gnats.

Another benefit is that it establishes a large population much quicker than Hypoaspis species, which means that this predatory mite has a shorter response time when problems arise. 

Where to apply?

Bye-o-Fly E is a soil-dwelling predatory mite so to improve efficiency release the predators in areas which mimic the natural habitat, such as wet litter areas, wet straw, soil and manure.

When to apply?

Apply one or two releases during the summer months as the Bye-o-Fly E predatory mite likes warmth. With summer temperatures it will develop rapididly, with an egg to egg cycle of about 10-15 days.
