Why Ladybirds Fail in Hydroponics: The Truth About Biocontrol
from Hydroponics Daily · host Eutrema Ltd
This episode explains why ladybirds (ladybugs) are often poor biological control agents in hydroponic systems: adults tend to fly away, larvae may not eat aphids effectively or can die, they can clog filters, and invasive or disease issues can arise. Alternatives are discussed, including lacewings, predatory mites (which can be sustained with pollen), parasitoid wasps, entomopathogenic fungi, and other IPM strategies, plus considerations about cost, availability, and storage. https://eutrema.co.uk/shop/pesticides-organic/eutrema-insecticidal-soap-sodium-free/
