Tips & Tricks

  • If extra pollen is added to establish orius, be aware that the western flower thrips also eat pollen. Thrips should always be monitored to ensure they are not benefiting from this practice.
  • Orius is attracted to yellow sticky traps, if they are being used in your crops, we suggest placing 1 for every 100 plants or more.
  • Orius is a diapausing insect and will become inactive during shorter/cooler days. We don’t recommend using it in the winter unless additional lighting is provided.

Orius Insidious

Awesome! Busy little bugs.

Orius insidiosus

Orius insidiosus were delivered quickly and they were lively upon arrival. I had to let them sit overnight (in the basement) and they were just as lively the next day. Easy to apply on 100+ houseplants. Thinking I may need to do a 2nd application as I'm still seeing a few thrips around, way less than before though! Also, it's been 1 week since application and I'm only seeing maybe 1 orius per plant, perhaps I don't have the right conditions for them or maybe their life cycle is finished. Generally pretty happy so far with the results.

Great control for thrips!

I regularly apply swirski mites to my large indoor plant collection to help with pests that may pop up. I recently noticed a few adult thrips in an area of my collection, and decided to add orius to the swirski mites. In just a few days there are no further adult thrips visible. The orius bugs arrived very active and happy, ready to get to work right away. Shipping was fast and packing excellent. Hightly recommend trying these guys!

Thrips are no more!!!

My thrips are gone 4 days After application. Predators are the way to go 💪

Half of my bugs were dead the next day when I went to apply them.

Hi Barbara,

I'm sorry to hear about your experience with our product. We always guarantee live delivery if the product was damaged or there were viability issues during transit. Since we have no control over the environment Orius was stored and released in, we can't take responsibility for its survival or efficacy. Any amount of storage can be stressful for the predator due to lack of humidity, water, and food. Please reach out to us if you'd like to learn more.
