Sciarid Fly Pest Solution: Hypoaspis Miles

Hypoaspis Description

Adult Hypoaspis (Pronounced: HYPE-O-ASP-ISS) are soil-dwelling mites which grow up to 1mm in length, they are pale brown in colour. The younger, nymph stage is almost white.

Hypoaspis naturally inhabits the top layer of soil or compost. It is used for controlling Sciarid flies (also known as fungus gnats).

Hypoaspis Life Cycle

Egg to adult takes about 34 days at 15ºC (60ºF) and 9 days at 28ºC. Hypoaspis adults and larvae both feed on sciarid larvae, but prefer the younger stages.

Hypoaspis can live for several weeks without the presence of food, and therfore can be used as preventatively. Adults will remain active for 4 or 5 months with a ready food supply.
