Amblyseius Cucumeris Treatment Bottles

Cucumeris is a specialized hunter that focuses on the early life stages of soft-bodied pests:

• Thrips: They consume the first-stage larvae (crawlers) of Western Flower Thrips, Onion Thrips, and others.
• Broad & Cyclamen Mites: Due to their small size, Cucumeris can navigate the tight crevices of new growth where these microscopic mites hide.
• Spider Mite Suppression: While not a primary spider mite predator, they will consume spider mite eggs and larvae, helping to slow the spread of an infestation.

For maximum activity and egg-laying, Cucumeris prefers moderate, stable environments:

• Temperature Range: 65F to 80F. While they can survive outside this range, their hunting and reproduction slow down significantly in extreme heat or cold.
• Humidity: Performs best at 65% to 75% RH. They are sensitive to dry air; if the humidity drops below 50%, their eggs may fail to hatch.
• Light Requirements: Not sensitive to day length; they are effective in all light cycles, including 24-hour veg cycles.

Bottle vs. Sachet: Sachets provide a slow release over 4 weeks. Choose the Bottle for an "instant strike" when you already see thrips or when you want to heavily treat a large area at once.

Cucumeris vs. Swirskii: Swirskii is more aggressive in high heat. Choose Cucumeris if your grow room stays at moderate temperatures or if you are working on a tighter budget for large-scale prevention.

The "Lower Canopy" Specialist: Thrips often drop to the lower leaves and soil. Choose the Bottle to broadcast material into the lower sections of the plant where sachets might be less effective.

1. The Gentle Tumble
Before opening, gently rotate the bottle end-over-end. Cucumeris tend to congregate at the top or bottom during shipping; tumbling ensures an even mix of mites and carrier material.

2. Application

• Direct Broadcast: Shake the material directly onto the leaves. Focus on the undersides and the "crotches" of the plant where branches meet the stem.
• Cups: If you have high-powered fans, use small cups to hold the material on the plant so the mites have time to crawl out onto the foliage.

Release IMMEDIATELY: Cucumeris are highly active and should be applied to the plants the day they arrive.

Storage: If you must wait, keep the bottle horizontal in a cool, dark place (55F to 60F). Do not refrigerate.

The "Invisible Army" Note: These mites are teardrop-shaped and nearly microscopic (0.5mm). They are tan to translucent and blend in perfectly with the carrier material.

Different tools for different situations. The bottle is a one-time treatment: you open it, release the adults, and the population does its work against an active infestation. There's no ongoing release — once deployed, that's it.

The sachet is a 30-day slow-release system with a pollen-based breeding medium. A resident predator population sustains itself on the plant regardless of whether a pest outbreak is in progress. It's the prevention tool; the bottle is the treatment.

Most growers use both in sequence: bottle to knock down an active colony, sachets to maintain coverage afterward. If you don't have an active problem and want ongoing protection, start with sachets directly.

Yes — and the bottle format is particularly well suited for established broad mite colonies. Polyphagotarsonemus latus shelters in bud tissue and furled new growth where contact sprays can't reach. A high-density adult release gets cucumeris into those same microhabitats immediately, rather than waiting weeks for a sachet population to build.

Broad mites are frequently misdiagnosed — their damage mimics overwatering, calcium deficiency, or viral infection. If your plants have unexplained distorted new growth, especially in aroids, peppers, or begonias, deploy cucumeris while you investigate further. The cost of a bottle is trivial compared to losing a choice plant to an undetected colony.

For very heavy infestations, a repeat bottle release 2–3 weeks after the first can accelerate control. Follow with sachets to prevent recurrence.

Match bottle size to the number of plants you're treating and the severity of the infestation. Smaller sizes cover a few plants or a small grow tent. Mid-size bottles handle a moderately infested collection of 10–30 plants. Larger bottles suit greenhouse bays or commercial spaces.

If you're unsure, err toward more rather than less. Releasing more predators than strictly necessary has no downside — excess adults simply disperse and decline naturally when the pest population is suppressed. Under-releasing means the pest can outpace the predators.

Yes — a week out from neem oil, you're in good shape. Neem breaks down quickly once dry: residual toxicity drops to safe levels within roughly 24–48 hours of application. Rinsing leaf surfaces with water before releasing is a good precaution but not strictly necessary at a week's distance.

What requires a longer wait: pyrethroids, neonicotinoids, organophosphates, and sulfur-based fungicides. These have residual toxicity that persists on plant surfaces for days to weeks. If any were applied recently, wait at minimum 2 weeks and rinse plants thoroughly before releasing.

When in doubt, spray first and time your bottle release for a week or more afterward. The pest population won't disappear in that window.

They'll survive and reproduce while prey is available, then naturally decline when it isn't — that's the system working correctly. Cucumeris doesn't establish permanently without a prey population and won't become a household pest. You will not end up with a predatory mite infestation.

After a bottle release, expect the predator population to peak within 1–2 weeks as they find prey and reproduce, then gradually decline over 3–6 weeks as the pest colony collapses. Once prey is exhausted, remaining adults disperse and die off naturally. No intervention required.

Cucumeris is available from a handful of online biological control suppliers in the US (including us) — but source quality varies more than the listings suggest. Predatory mites are perishable. What matters is how recently the colony was produced, how it was packed for transit, and whether the supplier ships on a schedule that keeps the product viable on arrival.

At FGMN we ship Monday through Thursday only, pack with temperature-appropriate cold or heat packs, and produce in small batches so you're not receiving product that's been sitting in a warehouse. We've been working with biocontrols for 20 years — we know what arrives healthy and what doesn't.

Garden centers and big-box retailers occasionally stock cucumeris sachets, but bottle product with a meaningful count is almost exclusively available through specialist suppliers online. If you're treating an established infestation, you need the right quantity from a source that knows how to get it to you alive.
