Ladybugs

They aren't picky eaters. If it’s soft, slow-moving, and shouldn’t be on your plant, it’s probably on the menu.

• Aphids: Their absolute favorite meal. A single ladybug can clear out dozens of these "sap-suckers" in a single day.
• Mealybugs & Scale: They specialize in hunting the young, mobile stages of these pests before they can hunker down and cause real damage.
• Thrips & Mites: While they aren't "specialists" here, a hungry ladybug is a great way to add an extra layer of defense against thrips larvae and spider mites.
• Pest Eggs: They’ll even snack on the eggs of moths and other garden invaders, stopping the next generation before it hatches.

They are highly adaptable biological controls that thrive in both indoor grow rooms and outdoor gardens, provided they have access to moisture and a consistent food source. In outdoor environments, ladybugs prefer temperate conditions with plenty of low-growth vegetation and "landing pads" like broad-leafed plants, especially during the cooler hours of dusk or dawn. For indoor cultivation or greenhouse settings, ladybugs perform best in stabilized temperatures between 18°C and 27°C with a relative humidity of 50% or higher. Because ladybugs are naturally attracted to light (positive phototaxis), indoor release requires managing light sources to prevent them from congregating on lamps rather than the canopy. Whether indoors or out, the most critical factor for "settling" ladybugs is the presence of soft-bodied prey like aphids, scale, or mites, and a light misting of water on foliage to encourage hydration and immediate foraging.

Choosing a biological predator is a matter of matching the "hardware" to the pest. Here is how to decide if our Native US Ladybugs are your best move:

• Ladybugs vs. Mites: Choose Ladybugs for large, visible colonies of Aphids or Mealybugs. Choose Predatory Mites for microscopic, "hidden" threats like Spider Mites or Broad Mites that live in the tight crevices of new growth.
• Ladybugs vs. Lacewings: Choose Ladybugs for immediate "knock-down" power (they arrive hungry and mobile). Choose Lacewing Larvae if you are working under 24-hour grow lights, as they don't fly and won't be distracted by the light.
• Ladybugs vs. Sprays: Choose Ladybugs to avoid chemical residues and "burn" on sensitive foliage. They are self-guided, searching every leaf so you don't have to.

Putting ladybugs out is actually a fairly simple process.

Mist the Canopy: Before release, give your plants a light misting of water. This acts as a "hydro-anchor" to keep your new ladybugs from flying away simply because they're thirsty.

Night Shift Only: Release them at dusk or 15 minutes after your lights go out. This gives them all night to hydrate, settle in, and find their first meal.

Start at the Bottom: Sprinkle them onto the lower stems or the soil at the base of the plant. They naturally crawl upward, so they’ll scan every leaf on their way to the top.

Look for the "Alligators": If you see weird, spiked larvae that look like tiny alligators a week later—congrats! Those are ladybug babies, and they are even more voracious hunters than the adults.

Keep them chill: If you need to, you can keep your ladybugs in the refrigerator - not the freezer! - for a week or so. The cool puts them into diapause, a they will simply "hibernate" until you're ready for them. Don't wait too long, this can kill them.

Shipping live ladybugs requires a balance of airflow and temperature control. Because ladybugs are shipped in a state of "controlled dormancy," our packaging is designed to keep them calm until they reach your garden.

• 2-Day Express Standard: To ensure your beetles arrive with high energy reserves for aphid hunting, we ship all orders via 2nd Day Air.
• Overnight Option: Highly recommended during peak summer months (July–August) or if you have an active infestation that needs immediate intervention.
• Strategic Dispatch: We ship Monday through Thursday only, or with the Friday Overnight Upgrade. They're generally okay if they do end up delayed, we just try to avoid that.
• Live Guarantee: Please advise of any problems within 24 hours of delilvery by emailing us at info@fgmnnursery.com

At FGMN, we only supply the Convergent Lady Beetle (Hippodamia convergens), which is 100% native to North America. Unlike the invasive Asian Lady Beetle (Harmonia axyridis), our native beetles are ecologically responsible and evolved to hunt local pest complexes without disrupting your local environment. They are the "correct" biological choice for US-based growers.

Not at all. Ladybugs are naturally gregarious, meaning they like to huddle for protection and moisture conservation. In the wild, they do this to overwinter. If you see them bunching up after release, it’s usually a sign they are acclimating to the temperature. Once they "warm up" and detect the chemical signals of pests (like aphid honeydew), they will disperse and begin the hunt.

Yes, but strategy matters. Ladybugs are generalists and may occasionally snack on a predatory mite if they cross paths. For the best Integrated Pest Management (IPM) results, use ladybugs first to "knock down" a heavy infestation, then wait 5–7 days to release your specialized mites. This ensures the ladybugs do the heavy lifting while the mites handle the precision cleanup.

The "residency time" depends on two factors: Food (such as our Breeder's Blend) and Water. If there is a high density of pests and you’ve provided a "hydro-anchor" (misting the leaves), they will stay until the food source is exhausted. Typically, you’ll see peak activity for 2–3 weeks. If they find enough food to lay eggs, their larvae (which look like tiny spiked alligators) will continue the hunt for several more weeks.

Ladybugs are positively phototactic, meaning they are biologically programmed to fly toward the strongest light source. If you release them during the day or under high-intensity LEDs, they will fly toward the sun or the bulbs and off your plants. Releasing at dusk or "lights-out" allows them to settle, hydrate, and start feeding, which significantly increases your retention rate.

Unlike the invasive Asian species, native H. convergens are not aggressive. While any insect can technically "pinch" if provoked, they do not seek out humans or pets. They are strictly focused on their "target hardware"—the soft-bodied pests currently damaging your plants. They are a safe, non-toxic biological solution for homes with kids and animals.
