Choosing beneficials

Ladybugs vs lacewings.

Two of the most-used biological controls in agriculture — and they're not interchangeable. Here's how to choose.

Direct answer

Ladybugs vs lacewings — which should I buy?

Pick ladybugs if aphids are your main pest, especially in gardens. Pick green lacewings for mixed pest pressure (aphids + thrips + whiteflies + mites), especially in greenhouses or indoor grows. They’re excellent together.

  • Ladybugs: best for aphid colonies & soft-bodied pests
  • Lacewings: best for mixed pest pressure
  • Lacewings excel in greenhouses and indoor grows
  • Pair them for layered control
  • Both are safe for plants, pets, and people

Ladybugs vs green lacewings — side by side

Live Ladybugs

Scientific name
Hippodamia convergens
Primary targets
Aphids, mealybug crawlers, scale crawlers, whitefly nymphs
Best environment
Gardens, greenhouses, indoor grows
Ships as
Adult beetles
Release method
Open container at base of plants at dusk
Best timing
Dusk, 55–80°F
Dispersal risk
Higher in open gardens (mitigate with staged release)
Typical starting count
1,500–3,000 for home gardens
Storage
Refrigerate 35–45°F
Best for
Aphid-dominant pressure

Green Lacewings

Scientific name
Chrysoperla rufilabris
Primary targets
Aphids, thrips, whiteflies, spider mites, mealybugs, small caterpillar eggs
Best environment
Greenhouses, indoor grows, mixed pest pressure
Ships as
Eggs or larvae (season-dependent)
Release method
Sprinkle eggs/larvae onto leaves near pests
Best timing
Dusk, mild temperatures
Dispersal risk
Lower — stays where placed
Typical starting count
500–1,500 eggs per release
Storage
Refrigerate 38–45°F, use within 3–5 days
Best for
Mixed pest pressure & enclosed environments

Both are commonly used in certified-organic operations. Results depend on environment, timing, and proper IPM practice.

When to use both

Greenhouse IPM

Combine lacewings (broad coverage) with ladybugs deployed against any aphid hot-spots. Add beneficial nematodes for soil pests.

Indoor / cannabis grow

Lacewings handle the mixed pest profile common in enclosed grows. Pair with ladybug larvae for fast knockdown on active aphid colonies.

Outdoor garden

Ladybugs lead. Add lacewings when whiteflies, thrips, or mites appear on top of aphid pressure.

Commercial program

Both species feature in most commercial IPM programs we design. Request a custom program.

Frequently asked questions

Ladybugs or lacewings — which one should I buy? +
If aphids are your main pest, start with ladybugs. If you have mixed pests (aphids + thrips + whiteflies + mites) or you grow in a greenhouse or indoor environment, lacewings are usually the better choice. The two are excellent together.
Can I use ladybugs and lacewings at the same time? +
Yes — they coexist well and target different pest profiles. A common pairing is ladybugs for aphid colonies plus lacewings for everything else.
Do ladybugs eat thrips and spider mites? +
Adult ladybugs feed primarily on aphids and other soft-bodied pests. They are not the most effective predator for thrips or mature spider mites — green lacewings are the stronger choice there.
Which is easier to release? +
Ladybugs come as adults, so the release is straightforward (open the container at dusk). Lacewings often ship as eggs or larvae — you sprinkle them onto leaves near the pests.
Which lasts longer in the environment? +
Lacewings tend to persist longer in enclosed environments. Ladybug adults can disperse from open gardens; staged releases mitigate this.
