## Questions & Answers

**Q: How is the predators environment maintained upon delivery? 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

### ⭐⭐⭐⭐⭐ Solved spider mite problem
*by R***T on 30 August 2021*

### ⭐⭐⭐⭐ Natural,silent, and effective—solid biological control for spider mites in grow or greenhouse setups
*by G***E on 20 September 2025*

These sachets are built for clean pest control—each one contains live Amblyseius californicus mites, natural predators that target spider mites without chemicals. You get 10 foil sachets, each designed to release predators gradually over time. Ideal for greenhouse plants, indoor grow tents, or sensitive crops where sprays aren’t an option. Application’s simple—hang sachets near affected areas and let nature do the work. Works best in warm, humid conditions (20–25°C). Mites are near invisible but get to work fast—expect results in 7–10 days. No smell, no residue, and safe around pets or edibles. Best used early in infestation—won’t reverse heavy damage but stops spread clean. 👍 Pros ✅ Natural predator—no chemicals or sprays ✅ Easy to apply—hang sachets, no mixing ✅ Premium foil—keeps mites fresh until use ✅ Silent and safe—no smell or residue ✅ Ideal for greenhouse, grow tents, indoor crops 👎 Cons ❌ Needs warmth and humidity—less effective in cold/dry setups ❌ Not instant—takes days to see results ❌ Won’t fix heavy damage—best for early control
