How To Attract Lacewings To Your Garden | More Aphid Control

Lacewings are one of those “wish I had more of these” garden insects. The adults are delicate, pale green, and easy to miss. The larvae are the real muscle: fast, hungry, and built to grab soft-bodied pests like aphids, whiteflies, mites, thrips, and small caterpillars. If you’ve ever looked at a plant and thought, “Those aphids are multiplying by the hour,” lacewing larvae are the kind of helper you want on patrol.

Getting lacewings to stick around is less about luck and more about giving them what they need in each life stage. Adults often feed on nectar, pollen, and honeydew. Eggs need safe places to sit. Larvae need prey, cover, and a yard that isn’t treated like a sterile lab. Put those pieces together and you can build a garden that keeps producing lacewings season after season.

What Lacewings Need In Each Life Stage

Adults Need Fuel

Most gardeners picture lacewings as nonstop hunters. Adult green lacewings in many species don’t live on insect prey. They run on nectar, pollen, and sugary honeydew. If your garden has plenty of pests but almost no small-flowered blooms, adults may pass through, lay fewer eggs, then move on.

Think of adult food as “stay awhile” energy. The more steady your nectar and pollen supply is across the growing season, the more often you’ll see lacewing eggs and larvae showing up where you need them.

Eggs Need Safe Placement

Lacewing eggs are tiny and look like pale grains perched on hair-thin stalks. That stalk is a built-in anti-cannibal design; it helps keep newly hatched larvae from eating their siblings right away. Eggs are usually placed near prey. If plants are blasted with water, coated in dust, or hit with broad insect killers, egg survival drops.

Larvae Need Prey, Cover, And Time

Lacewing larvae are often called “aphid lions” for a reason. They hunt aggressively, but they still need a few basics: places to hide from birds and ants, steady prey, and enough time to work before a spray resets everything. When you create a yard that lets larvae hunt for days and weeks, pest pressure often eases without the rollercoaster of repeated treatments.

How To Attract Lacewings To Your Garden With Simple Habitat Tweaks

Plant Nectar Sources With Small, Open Blooms

Lacewings do well with flowers that have easy access to nectar. In plain terms: small blossoms, clustered blooms, and “open” shapes. Many herbs fit this pattern when you let them flower.

• Herbs to let bloom: dill, cilantro, parsley, fennel, mint (in a pot), thyme, oregano, basil
• Easy annuals: sweet alyssum, calendula, cosmos, buckwheat
• Perennials (site-fit matters): yarrow, coreopsis, coneflower, asters

You don’t need a meadow. A few “nectar strips” along bed edges or between veggie rows can be enough. Aim for staggered bloom times so something is offering nectar from spring into fall.

Leave A Few “Messy” Patches On Purpose

Lacewings use shelter. That can be leaf litter under shrubs, a thick border planting, tall ornamental grasses, or a hedge that stays put through winter. If every corner of the yard gets cut down to bare soil, overwintering sites shrink.

Try a simple rule: keep one area that you clean up late, not early. Trim and tidy when nights are reliably warmer, and leave some leaf litter under non-vegetable plantings where it won’t bother you.

Control Ants That Guard Aphids

Ants “farm” aphids for honeydew and will chase off predators, including lacewing larvae. If you see ants marching up stems to aphid clusters, you’re watching a security detail in action.

Practical fixes:

• Use sticky barriers on tree trunks and sturdy stems where it makes sense (keep it off delicate plants).
• Trim bridges: prune branches that touch walls, fences, or other plants that act like ant highways.
• Water management: soggy mulch against foundations can boost ant activity; adjust irrigation if needed.

Skip Broad-Spectrum Insect Killers When You Can

If you spray a “kills everything” product, lacewings get hit in multiple stages: adults, eggs, larvae. That breaks the cycle that keeps them returning. If you do need treatment, focus on narrow targets and timing that spares beneficial insects.

UC’s Integrated Pest Management guidance for green lacewings stresses growing flowering plants for adults and avoiding broad-spectrum, persistent pesticides that reduce natural enemies. UC IPM’s green lacewings guidance lays out those basics in plain language.

If you want a simple decision frame, the EPA’s overview of IPM explains the “prevention first” approach and how multiple tactics fit together. EPA’s IPM principles is a solid reference for building a plan that relies less on routine spraying.

Give Lacewings A Water Source Without Creating Mosquito Soup

Adult lacewings will use water in the garden, yet you don’t need a pond. A shallow dish with pebbles works, refreshed often. Drip irrigation and morning watering also help by keeping nectar-producing plants from stressing and shutting down bloom early.

Keep standing water moving or emptied on a regular schedule. A shallow dish is only useful when it stays clean.

Use Light Wisely At Night

Many lacewings are drawn to lights. Porch lights can pull them away from beds and toward windows. If you want more activity near plants, reduce bright night lighting close to your growing areas. Use motion settings or warm bulbs when possible. Small changes can keep beneficial insects where you want them: around plants, not trapped by a patio fixture.

Planting Plan That Keeps Lacewings Fed From Spring To Frost

You’re not trying to plant “lacewing flowers” as a single magic pick. You’re building a rotation of blooms. Start with early nectar, keep mid-season rolling, then finish strong in late season when many gardens go quiet.

Early Season

Early blooms help adult lacewings refuel when they first show up. If you already grow herbs, you’re halfway there. Let a few plants bolt and flower on purpose. You can still harvest leaves from others.

Mid Season

This is when pest pressure often spikes. Keep at least one flowering option going in each bed or along each edge. Sweet alyssum is a classic for a reason: it blooms hard, doesn’t take much space, and fits between crops.

Late Season

Late blooms matter because lacewings may still be active while fall pests ramp up. Asters and late-flowering herbs can keep nectar available when many annuals fade.

The Cornell IPM factsheet on common green lacewings notes that larvae feed on many soft-bodied pests while adults commonly feed on nectar and pollen. That split matters when you plan your garden: prey for larvae, flowers for adults. Cornell’s green lacewing factsheet is a strong primer for gardeners who want the life-cycle view.

Fast Signs You’re Already Attracting Lacewings

Eggs On Fine Stalks Near Aphids

Check the undersides of leaves near aphid colonies. Lacewing eggs can look like tiny pins on threadlike stems. If you spot them, resist the urge to spray a general insect killer “just to be safe.” Eggs are your sign that help is incoming.

Larvae That Look Like Tiny Alligators

Lacewing larvae are often gray or brown, with curved jaws. Some species carry debris on their backs. If you see one in action, it’s hard not to root for it.

Adults Resting In Shady Spots

Adults may hang out in dense foliage during the day. At dusk, you might notice them fluttering around flowers. If you’ve reduced night lighting near beds, you may see fewer around windows and more around plants.

Common Mistakes That Keep Lacewings Away

Spraying “Just Because”

Routine spraying breaks biological control. It can also rebound pests: many pests reproduce fast, and beneficial insects often take longer to rebuild. If you’ve been stuck in a cycle where pests keep returning right after treatments, this is a likely reason.

Only Planting Big, Showy Blooms

Large double flowers can be hard for small insects to use. Mix them with clusters of small blooms that provide easy access to nectar and pollen. It’s not about aesthetics versus function; you can have both. Just add a few small-flowered “workhorse” plants.

Cleaning Every Scrap Of Leaf Litter Too Early

A perfectly bare garden can be a rough place for beneficial insects to overwinter. Leave a strip, a hedge base, or a border that stays a bit wilder until later in spring.

Letting Ants Run The Show

If ants guard aphids, lacewing larvae get pushed off prey. Ant control is not glamorous, but it can change the whole story in a garden bed.

Action Checklist For A Lacewing-Friendly Yard

The list below is meant to be practical. Pick the pieces that fit your space and your tolerance for “tidy.” When you do several of these at once, lacewings have a reason to stay.

• Let two or three herbs flower in each growing area.
• Add at least one small-flowered plant that blooms for a long stretch.
• Keep a border or corner with leaf litter or dense cover through winter.
• Handle ants where they guard aphids on stems and trees.
• Use pest control tactics that spare beneficial insects when possible.
• Water in ways that keep nectar plants blooming.
• Reduce bright night lighting near beds.

Table: What To Change First When You Want More Lacewings

If you only change one or two things, start with adult food plants and spray choices. Those two shifts often decide whether lacewings cycle through your garden or settle in.

Should You Buy Lacewings And Release Them?

Buying lacewings can work in some situations, yet it’s not a shortcut if the yard is missing food plants or gets treated with broad insect killers. If you release larvae into a garden that has no nectar sources, no shelter, and frequent spraying, you may get a short burst of help and no staying power.

When Releases Make Sense

• You have a clear soft-bodied pest issue (aphids, whiteflies, mites) and you can pause broad sprays.
• You’ve already added flowering plants or you have honeydew from pests that adults can use.
• You can release close to pest clusters, in cooler parts of the day, with light watering available.

When Releases Disappoint

• Ants are actively guarding aphids on multiple plants.
• You need instant knockdown across the whole yard.
• Heat, wind, and dry conditions are harsh at release time.

Even if you never buy a single lacewing, thinking like a “release manager” helps: where would larvae hide, what would adults eat, what would kill them off? Build the yard around those answers and you often get lacewings for free.

How To Deal With Aphids While Lacewings Build Up

Sometimes aphids are already thick when you start making changes. You can still protect lacewings while reducing pest pressure.

Start With Physical Control

• Pinch off the worst-infested tips and bag them.
• Rinse aphids off with a firm spray of water, aimed under leaves.
• Cut back nitrogen-heavy feeding that pushes soft new growth aphids love.

Use Spot Treatments Instead Of Whole-Garden Treatments

If a single plant is a disaster, treat that plant. Keep the rest of the yard as a refuge for beneficial insects. This is one of the simplest ways to keep lacewings present while still acting on a problem.

Watch For The Turn

The “turn” is when you start seeing more predator activity than new pest growth: lacewing eggs near aphids, larvae on leaves, and fewer fresh clusters each day. Once you see that turn, hold steady. Don’t wipe the board clean with broad sprays right when predators are doing the job.

Table: Simple Plant Choices That Fit Lacewings And Small Gardens

This table is meant as a practical menu. Pick what fits your climate, sun, and space. Mix herbs with a few long-blooming flowers and you cover adult food across the season.

A One-Week Plan To Start Seeing More Lacewings

Day 1: Pick Two Flowering “Fuel” Plants

Choose two options you can add right now: a flowering herb you’ll let bloom and a small-flowered edging plant. Put them within a few feet of the crops that get hit by aphids.

Day 2: Mark One “Late Cleanup” Zone

Decide where you’ll leave leaf litter or dense cover longer. It can be a border under shrubs, behind a shed, or a hedge base.

Day 3: Check For Ant Trails

Follow ants from the soil up stems and trunks. If they lead to aphids, set a barrier or remove bridges. This step often changes predator success fast.

Day 4: Reduce The Worst Aphid Clusters

Prune tips, rinse leaves, and bag infested growth. This lowers the immediate pressure while predators build.

Day 5: Pause Broad Sprays

If you’ve been using general insect killers, stop for a stretch and watch what shows up. Use spot control only where needed.

Day 6: Dusk Check

Walk the garden near sunset. Look for adults around flowers and check leaves for eggs. If porch lights are bright near beds, dim them or switch to motion settings.

Day 7: Record What You See

Take a quick note: where aphids are still heavy, where eggs appeared, where larvae showed up. Use that info to place more flowering plants near trouble spots.
