› Grower guide More information about Caterpillar Control
Stop loopers, armyworms, cutworms, and borers before they ever chew — by hitting caterpillars at the egg stage, where damage is cheapest to prevent. No residue, harvest-safe, no resistance.
Caterpillars are the larvae of moths and butterflies, and only the larval stage harms your crop (the adult moths just feed on nectar). Caterpillar biological control targets the eggs and young larvae, so the feeding damage that sprays only react to never starts. Trichogramma for caterpillars is the proven, residue-free backbone.
Why choose biological caterpillar control
Beneficials leave zero residue, are safe for pollinators and workers, avoid resistance, and integrate with organic and IPM programs — including cannabis and hemp, where borers and worms hit hard. Best of all, prevention beats cure: catch the eggs and you skip the damage entirely.
How to build your caterpillar program
Timing is everything. Track moth-flight with pheromone traps or degree-day models, then release Trichogramma before the eggs hatch so the wasps parasitize them as they're laid. Once larvae are active, add green lacewings and a Bt-type biopesticide — Bt is highly effective, harmless to your beneficials, and a staple of caterpillar IPM.
What's in this collection
- TRICHOforce (Trichogramma) — tiny wasps that destroy caterpillar (moth) eggs before they hatch.
- Green lacewing larvae (CHRYSOforce R) — feed on eggs and young larvae; also as eggs on cards and adults.
- SuffOil-X — horticultural oil for compatible suppression of eggs and small larvae.

Frequently asked questions
How does Trichogramma control caterpillars?
The wasps lay eggs inside moth eggs, so the caterpillars never hatch — stopping damage before it begins.
When should I release caterpillar parasites?
At the start of moth-flight and repeated through the egg-laying period; pheromone traps and degree-day models help you time it.
What is the best biological control for caterpillars?
Trichogramma egg parasites for prevention, plus lacewings and a Bt-type biopesticide for larvae already present.
Can I use Bt with beneficial insects?
Yes — Bt is caterpillar-specific and harmless to your wasps, lacewings, and pollinators, so it pairs perfectly with biocontrol.
