Fungus Gnat Control and Treatment with Predatory Mites

Fungus gnat control and treatment can be effectively achieved with soil-dwelling predatory mites. As a specialist predatory mite breeder on the Coffs Coast, we have nearly 10 years’ experience with Hypoaspis. Hypoaspis feeds on fungus gnat larvae, thrips pupae, springtails and other small soil inhabiting insects. They are most effective when applied before the pest population becomes established or when it is at a low density. Deploying Hypoaspis miles is a natural and eco-friendly way to protect the roots of your crop. Furthermore, they can still be effective even in conjunction with some organic drenches used for fungus gnat control and treatment.

Hungry Hungry Hypo(aspis) for Targeted Fungus Gnat Control and Treatment

Adult mites consume between one and five prey per day. Adult Hypoaspis are between 0.5 mm and 1 mm long, with females larger and much more common than males. Adult females are light brown in colour. The life cycle of Hypoaspis consists of egg, larva (6 legs), nymph (8 legs) and adult. The whole life cycle takes about 10 days at 25°C but can vary from 7 to 30 days depending on temperature. At temperatures below 12°C Hypoaspis is inactive, but it will not die unless frozen. Eggs are laid in the soil and hatch into larvae in 1–3 days. Hypoaspis lives in the top 1–2 cm of soil and can be seen moving quickly on top of the soil when the surface is disturbed or pots are tapped. It can survive for up to 7 weeks without insect prey, by feeding on organic matter, plant debris and nematodes.

How Do I Get Rid of Fungus Gnats and Thrips?

We breed our predator mites to be tough and resilient. As such, our breeding program incorporates environmental stresses to ensure every batch is ready for the toughest conditions. Simply release the predators at the right time, and in the right amount, and let them do what they do best. It can take a little more time than dousing the area with pesticides but they work cleanly and efficiently, selectively ridding you of the target pests. Rest assured, we’re happy to advise you on how and when to achieve the best fungus gnat control results.

Fungus Gnat Control

More Information

Best results are achieved by releasing Hypoaspis when pest populations are at a low level. Monitor gnat levels with yellow sticky traps or with by tapping pots and observing the small black fungas gnat adults flying around and release the predator preventively as soon as gnats are detected. Areas of greater infestation must be identified for more concentrated treatment or possible modification of the growing environment. Some pesticides are harmful to Hypoaspis, particularly if applied to the soil. Discuss your chemical usage with us before releasing the predator.

Predators are packaged in a peat and vermiculite mix for commercial use. They are sold by the litre. Each litre contains 15 000 mites at all life stages. The presence of mites can easily be checked on arrival by disturbing the mix; the mites should be seen moving across the surface. However, if the temperature is low they will be inactive. In warmer conditions the top of the mixture may dry out slightly during shipment; the mites will then congregate toward the bottom of the container, or around moist clumps of media. Hypoaspis should be released as soon as possible on receipt and not stored below 10°C or above 25°C.They can be held at room temperature for 1–2 days, although this not recommended.

Preventive treatment: 15 000 per 100–150 m2 of bedding, or 15 000 per 200–300 150-mm pots. Treatment of the greenhouse floor is recommended if soil is conducive to fungus gnat development. Occasional treatment of the perimeter of greenhouses has proved effective. For propagation areas, very early treatment is critical for successful control. For curative treatment where fungus gnats are well established double above rates. Even distribution will give best results, so where possible treat all areas. Predators will move quite well over the soil. If pots are touching and pest levels are low, distribution is not as critical. Apply early at full rates and allow time for predators to spread. Do not mix Hypoaspis with the potting medium before potting, because they live mainly in the top 1–2 cm of soil and may not survive below that depth.

After release, monitor Hypoaspis as well as pest numbers. Hypoaspis can be hard to find. A reduction of adult fungus gnat numbers should be apparent in 2–3 weeks. Identify any hot spots of pest activity, as these may require re-treatment or spot treatment. Re-release Hypoaspis if necessary.

Hypoaspis

SKU: N/A

Hypoaspis, is a soil-dwelling predatory mite that feeds on fungus gnat larvae, thrips pupae, reptile mites and other small soil inhabiting insects. They are great for dealing with fungas gnats in your indoor plants and treating mites on reptilian friends.

Adult Hypoaspis are between 0.5 mm and 1 mm long, with females larger and much more common than males. Adult females are light brown in colour.

The life cycle of Hypoaspis consists of egg, larva (6 legs), nymph (8 legs) and adult. The whole life cycle takes about 10 days at 25°C but can vary from 7 to 30 days depending on temperature. At temperatures below 8°C Hypoaspis is inactive.

Eggs are laid in the soil and hatch into larvae in 1–3 days. Hypoaspis lives in the top 1–2 cm of soil and can be seen moving quickly on top of the soil when the surface is disturbed or pots are tapped. It can survive for up to 7 weeks without insect prey, by feeding on organic matter, plant debris and nematodes.

Each litre of Hypoaspis contains 30,000 predators. Prices INCLUDE GST and freight.
