It can also be used against Broad Mite ( Polyphagotarsonemus latus ). The Amblyseius californicus are supplied in a unique foil sachet. Each sachet will slowly release the predators for around 4 weeks, protecting the plant from outbreaks during this time. What Are Spider Mites? Spider Mites, or Two Spotted Mites ( Tetranychus urtica ), are a common pest found in greenhouses or hydroponic set ups. Spider Mites cause leaf damage by sucking out the contents of plant cells. Evidence of their activity will be clear from the damage they cause, where plants are left discoloured with white splotchy patches across the leaves. How To Apply Our Californicus Spider Mite Killer Sachets Select The Plants You Wish To Treat Distribute the sachets and select which plants you wish to treat for Thrip infestation. Hang 1-2 Sachets Per Infested Plant Simply hang 1-2 sachets per infested plant. The sachets already contain an emergence hole so there is no need to open them. The sachets each contain a hook for easy application. Enjoy Natural Spider Mite Predation The Californicus mites will proceed to locate and consume the Thrip pests. Each sachet will release fresh predators for 3-4 weeks . Sachets should then be replaced to ensure a steady flow of fresh predators are active on your plants. Sachets Supplied In Superior Foil Packaging Each foil sachet can produce up to 3x more predators than the paper equivalents! That's around 750 predators per sachet. The superior quality of foil sachets ensures the predator breeding system has perfect internal conditions. This creates larger numbers of higher quality and healthier predators. Foil sachets ensure the breeding system is better protected against environmental conditions such as; temperature variations, dampness from watering, changes in humidity and so forth. Foil sachets can be disposed with plant waste. What Conditions Do The Californicus Predators Require? Temperatures should be between 10-35℃ . Ideally there should also be a relative humidity above 60% , however lower levels can be endured by the californicus . Amblyseius californicus is a living creature and can be affected by residual chemical pesticides present on plants. As a general guide, refrain from using any chemical treatments prior to predator application, or check with Dragonfli for information on the potential effects of certain products on predatory mites.

If anyone tells you that this method doesn't work, they are laying 🙄 The main thing is consistently. Sachets have to be replaced every 4 to 8 weeks and you will not see spidermites ever. I have over 100 big plants in a small space and a lot of them are marantaceae. It works Review: It works! - I was sceptical about whether it would work, as my citrus tree was badly infested with spider mites and looking very poorly. But it really worked. It is now looking healthy again and growing lots of new leaves. ## Features - Part of the Dragonfli Spider Mite Preventative System - More information at dragonfli.co.uk.

I'm put off ordering if they arrive in an envelope or box being 4degrees outside** A: It’s a good question. I can’t see how they would survive extreme temps **Q: Hi, how long does it take for the sachets to have an effect? I've had them out for 24 hours and plants look the same (covered in mites). Thanks :)** A: The are great when using them constantly, but sounds like your looking for an effect. If yo are putting the bags in after an infestation has begun then it's to late but a tube of them in sawdust with heavy concentration of predators with cure that, use the bags as a deterrent more than a cure, changing them regularly to maintain there presence. Some will be out now in the time you say you put them up, not enough to touch infestation, go big it's the only way. **Q: How do I properly open the packet the instructions are not totally clear?!** A: No need to open the bags usually, there is a way out for them built into the little packets. After a couple of weeks I cut out a small triangle on the top of one side of them. There is no need to do this, **Q: How long does the protection last for? How often will I need to buy this to keep infestation at bay?** A: I used 2 applications and it sorted it ## Customer Reviews ### ⭐⭐⭐⭐⭐ It works *by I***K on 4 April 2026* I've been using them for years.
