Amblyseius swirskii Mite Predator
Amblyseius swirskii are an excellent beneficial mite for preventative control of thrips, whitefly and various mite species. A. swirskii adults resembles Amblyseius cucumeris in appearance and take on the color of what they are consuming. Adult females lay eggs arranged on leaf hairs.
When temperatures reach 77°F the larvae hatch and mature to adulthood in about a week. This predatory beneficial prefers warm, humid environments but survives cooler nights by moving to lower locations on the plants. They do not enter diapause when temperatures cool so they are efficient in areas where temperatures drop below 60°F; however, eggs do not hatch in temperatures that low.
Repeated releases of adults will be necessary in the presence of low temperatures. Depending on the stage of development, the Amblyseius swirskii can consume about 10 thrips or whitefly larvae a day and up to about 20 whitefly eggs per day. This beneficial can survive by consuming pollen and mold.
In warm and humid environments they reproduce quickly, therefore they are an optimal choice for crops grown under protection in warm environments. Typically, they can be used until nighttime temperatures drop below 60°F.
- Temperature: 77-85°F (can remain active to 60°F)
- Relative Humidity: 70%
- Before the onset of infestation.
- Shaker Tube & Bag – 2-5 per square foot biweekly as needed. Use shaker tube/bag releases for spot treatment.
- Sachet Releases – Place one sachet every 6 feet of crop row monthly as needed. Use sachets for prevention or to control low mite populations.
- Amblyseius swirskii is not recommended for use on infestations on tomato crops.
PLEASE NOTE: All Mite Predators require additional processing time due to rearing and collection times. Additional information can be found on the Shipping Tab to identify the earliest shipment date.
Make sure the crop and floor are dry when applying. If crop and/or floor are wet, water can enter the packaging and result in some predatory mites being lost.
Open the shipping box of the sachets in the crop. Separate sachets by tearing along perforations. Do not hang where sachets will be directly exposed to intense sunlight. Mini-sachets have attached hooks and can be hung where needed. Hang inside plant canopy where possible. Mites emerge from sachets for 3-6 weeks.
Shake small quantities of predatory mites onto crop where pest pressure is heaviest. Immediately before opening, gently rotate the container to distribute mites evenly throughout the carrier material and continue rotating during application, keeping material mixed.
5 Liter Bag:
Apply evenly throughout the crop and try to apply to foliage, not to media.
- Ships via Overnight shipping methods only. This does not take processing time into account. Overnight Shipping refers to the time frame for delivery after the shipment date.
- Orders ship on Tuesdays only.
- Order by Tuesday for shipment the following Tuesday. 7-day minimum processing time prior to shipment.

Certain sizes of this product are shipped in specially designed, water resistant sachets that contain colonies of predators. The sachets contain approximately 250 predators each. The colonies will continue to breed inside their sachets once placed into crops. In addition, the sachets allow for controlled release, continued predator emergence, can be used indoors/outdoors, and with overhead irrigation.
Sachets will be active for about 2-4 weeks depending on infestation level and predator establishment. Keep out of direct sunlight, store in a cool place, but do not refrigerate.
What's In The Package:
- All sachets are packed with a mixture of immature and adult A. swirskii. This ensures ongoing release from sachets for 2-4 weeks after placement.
- The 1 Liter Tube and 5 Liter Bag are packed with adult A. swirskii ready to feed on active mite populations.
Warning & Toxicities: Use within 18 hours of receipt. Do not use adjacent to heating pipes.
Use caution if A. swirskii will be used in locations where Phytoseiulus persimilis and/or Aphidoletes aphidimyza are being used. There can be compatibility issues.
