The fast-moving pirate bug for thrips that are already established

When thrips pressure is high and visible, predatory mites can be too slow to catch up. Orius insidiosus, the minute pirate bug, is a fast, mobile generalist that goes after adult thrips as well as spider mites, aphids, and whiteflies. It uses piercing mouthparts to kill prey, and it will keep killing even when it is not actively feeding, which makes it a dependable choice for knocking down an outbreak that is already underway.

Fast knockdown of adult thrips Kills even when not feeding Ships live, overnight Tuesdays

Live insects ship on Tuesdays only and arrive Wednesday. Orders must be placed 7 days in advance. Anything ordered by 3pm EST Tuesday ships the following Tuesday by UPS overnight shipping.

Slow preventative mites vs. a fast pirate bug
Preventative mites alone
  • Predatory mites can lag behind a heavy outbreak
  • Mites mainly take young thrips
  • Sprays scatter thrips and miss hidden ones
  • Chemicals leave residue and re-entry waits
  • Broad sprays harm other beneficials
  • Only knocks down what you hit
Orius insidiosus
  • Fast, mobile predator built for established pressure
  • Orius attacks adult thrips as well as larvae
  • The pirate bug actively hunts thrips across the canopy
  • No residue and no re-entry interval
  • Works alongside your mites and other predators
  • Kills prey even when it is not actively feeding
Why Orius handles a heavy outbreak

Goes after adult thrips Fast knockdown

Unlike predatory mites that focus on young thrips, Orius attacks adult thrips too, which is what lets it turn around an infestation that is already established and visible.

A hungry generalist

Beyond thrips it also feeds on two-spotted spider mites, aphids, and whiteflies, so one predator helps on several soft-bodied pests at once.

Rapid 3 to 4 week cycle Both stages feed

With eggs hatching in 4 to 5 days and nymphs maturing in 7 to 10, Orius runs a quick 3 to 4 week lifecycle, and both nymphs and adults feed aggressively on pests.

Kills beyond hunger

Using its piercing rostrum, Orius kills thrips and mites even when it is not actively feeding, adding extra pressure in a high-count infestation.

Highly mobile

The adults move quickly and fly across the crop, seeking out thrips hot spots so coverage is not limited to where you released them.

Simple release

Tap the carrier out among the plants, ideally near flowers and pollen. There is nothing to mix and no gear needed.

How Orius knocks down a thrips outbreak

1

Release near the flowers

Tap the pirate bugs out among the plants, focusing on flowering areas where thrips and pollen concentrate.

2

They hunt across the canopy

The mobile adults move through the crop seeking out thrips adults and larvae in the hot spots.

3

They kill on contact

Using piercing mouthparts, Orius kills thrips and mites, continuing even when not actively feeding.

4

Both stages keep working

Eggs laid in the plant hatch into nymphs that feed too, so the population presses the outbreak on a 3 to 4 week cycle.

Orius or a predatory mite? Orius is the fast responder for established, visible thrips. Predatory mites like cucumeris or swirskii are the steady preventative. Many growers use Orius to knock a problem down, then mites to hold it. Call us and we will map it out. Call or email us: 716-217-0353 / help@
Frequently asked questions
Reach for Orius when thrips are already established and visible and you need faster knockdown than mites provide. It attacks adult thrips, not just the young stages. For quiet, preventative coverage, cucumeris or swirskii is more economical. A common plan is Orius first, then mites to hold the line.
Yes. Orius is a generalist that also feeds on two-spotted spider mites, aphids, and whiteflies. It is especially handy when thrips and mites are both present, since one predator addresses both.
It does best where pollen is available, so flowering plants help it establish and persist. If your crop is not flowering yet, releasing near any pollen source or pairing it with a supplemental food can help. Ask us for tips on your specific setup.
