How to release Hypoaspis miles?

  • For best results avoid watering for 1-2 hours before and after release. Use open structure soil that is moist and rich with organic matter.
  • Gently rotate the tube to evenly mix the mites in the carrying material.
  • Disperse mite mixture as small piles on the soil or rockwool slabs and any other place where soil pests can reside.
  • Leave the empty tube near the plants for 24 hours to allow any remaining mites to crawl out.

Can you store Hypoaspis miles?

We recommend releasing predatory mites immediately upon arrival.

If storage is necessary Hypoaspis can be stored for 3-5 days in a cool (10°C - 15°C) dark place. Lay the bottle horizontally and avoid any contact with direct sunlight.

How to check the quality of the mites?

Due to low temps during shipment predatory mites tends to huddle in the middle of the tube. If at first you don’t see any movement, allow the shipment to come to room temperature before conducting a quality check.

To check gently rotate the tube to evenly mix the mites. Pour a small sample on a white piece of paper and you’ll see Hypoaspis crawling from the pile. You may need a 10x lens to see the mites, they are about 0.5mm in size. 

How to promote establishment?

  1. Use open structure soil that’s rich in organic matter such as algae, plant debris, etc. The organic matter will serve as a food source for hypoaspis when there is a shortage of prey.
  2. Keep soil moist and warm (soil moisture content of 60% or more and temp of 20-25C). Avoid overwatering as this can create drowning conditions in the soil.

Since its a soil-dweller these conditions are relative to the soil rather than atmospheric conditions. Colder temperatures can hinder the predators' ability to reproduce or develop to a certain degree.

How to spot Hypoaspis after releasing?

Hypoaspis is a tiny brown mite that is found in the soil or other growing mediums. In order to effectively scout for these mites use a 10X lens and inspect the top 100cm of soil or growing medium. Monitoring population of fungus gnat larvae can also be a good indicator of how well Hypoaspis is establishing in the crops.

How long till you see results and how often should you be reordering?

Hypoaspis start breeding is soil right after its release. Moisture contents, organic matter are key players in successful establishment of Hypoaspis. Availability of prey also help in population growth. Chemical pesticides can affect its population development.

Frequently asked questions

Can I use Entomopathogenic nematodes with Hypoaspis miles?

No harm to use them together. Promoting diversity in the soil will help achieve better and quicker control. 

Can I water my plants after releasing Hypoaspis miles?

Yes you can. Hypoaspis thrives in moist soil, just make sure not to overwater the soil as this can create drowning conditions for the mites.

Can I use other predatory mites (Phytoseiulus persimilis, Neoseiulus californicus, Amblyseius swirskii, Neoseiulus cucumeris) with Hypoaspis miles?

Yes they work well together. Hypoaspis is a soil-dwelling mite and won’t cross paths with the mites mentioned above. Using these predators together will help achieve control faster.
