Slow Release Predatory Mites (Neoseiulus californicus)
For Spider Mite Control | Preventative + Long-Term Release
If you’ve spotted tiny webs or specks on your leaves, there’s a good chance spider mites have moved in — but don’t worry, SPICAL ULTI-MITE makes it easy to get ahead of them, even if you’re brand new to plant care. These slow-release sachets are filled with tiny, invisible-to-the-eye predatory mites that naturally hunt down spider mites so your plants can thrive. Just hang one sachet on each plant (or every few plants if they’re close together and their leaves are touching), and let nature do the rest.
No spraying, no mess — just quiet, natural protection that works indoors and in greenhouses. Great for houseplants, tropicals, or larger plant collections. Think of it as setting up tiny bodyguards for your leaves!
Each little sachet contains Neoseiulus californicus — a tiny predatory mite that hunts and feeds on spider mites. Inside the sachet, there's a special mix of bran and food mites that support a small colony of predators. Think of it like a cozy starter home where they hatch, grow, and multiply.
As the days go by, the predatory mites begin to venture out through a tiny built-in exit hole in the sachet, spreading into the surrounding plant canopy in search of spider mites. They don’t bite plants, pets, or people — they’re only interested in mites! This slow and steady release gives your plants consistent, natural protection for several weeks without the need to spray.
It’s a gentle, effective way to guard your plants — especially in warm or dry conditions where spider mites love to thrive. Just hang, relax, and let the good bugs handle the hard work.
🔥 Best used as a preventative or at the very first sign of spider mites.

What to Expect Upon Arrival:

Important Notes
We import most biological controls fresh to help ensure customers receive active, viable beneficial insects, mites, and nematodes. Because these are living products with limited shelf life, we do not keep most biologicals stocked in-house.
Please inspect your package and product immediately upon arrival, before release. If you have any concerns about condition or viability, contact us before releasing at admin@optimizeorganics.ca with your order number and clear photos of the package and product. Once beneficials have been released, it becomes much more difficult for us to assess their condition on arrival.
Biological pest control is rarely a one-and-done release. In most active pest situations, sequential releases are needed to build and maintain beneficial populations while pest eggs continue to hatch and existing pest pressure is reduced.
Avoid spraying pesticides, oils, soaps, or other residues immediately before or after release unless compatibility has been confirmed, as these may harm beneficials.
