Beneficial Insects – Biological Pest Control

Predatory mites, parasitoid wasps, nematodes: three strategies, one goal. This course shows how biological pest control actually works – why it takes days to weeks instead of seconds, when to deploy preventively and when curatively, and how to find the right hunter for every pest.

Hunters, Not Poison: How Predator Pressure Works

A beneficial doesn’t kill at the push of a button – it shifts the balance of power. That’s not a drawback, that’s the principle.

Spider Mites: the Duel of the Mites

Two predators, one prey, two completely different strategies – specialisation is a trade-off, not superiority.

Substrate Strike Force: Fungus Gnats & the Root Zone

Fungus gnat larvae live invisibly in the substrate – a different terrain needs different defenders.

Aphids: the Escalation Ladder

Three beneficials, one prey – but not three equally strong tools, rather a ladder from gentle to hard.

Thrips & Whitefly: the Light Question

Two standard predators, one photoperiod problem – but temperature plays a big part too.

Logistics of Live Goods

"Organic" isn’t a reliable category – only the specific active-ingredient/beneficial pairing counts.

Is It Working? Success Checks and Honest Limits

Success rarely looks like zero pests – and sometimes biology alone simply isn’t enough anymore.

The Standing Army – Feeding Instead of Starving

For advanced growers: a fed predator population hunts less per head – and still controls pests better.
