Solved spider mite problem
I had a bad infestation of spider mites and after using neem oil and soap that works but it's a real hassle,I now use these as a preventative measure instead, at the first sign of any mites I add these sachets and the mites dissapear ,they don't work on a full on infestation though ,gets pricey but keeps mites away so job done .

Natural,silent, and effective—solid biological control for spider mites in grow or greenhouse setups
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

It really works
Had thousands of mites all over the patio and up the walls of the house and coming in the upstairs windows so had to get rid of them hung them outside around the worst areas and then couple of days later they were all gone

Quick but disappointed with card handle
Product came very fast. Was easy to put on the plants but the hanger is made of card, so many of them have become wet and tore off onto the ground. I will have to keep checking the plants every day and see if the larvae hatch and are okay. This is a bit disappointing as l thought the product would all be made of foil so it stayed on the plant so the larvae can eat the spider mites. Now lm not sure it will even work.

Saved my plants
We were inundated with spider mites on our indoor plants. Had tried various alternatives to the nuclear uption of chemical bombardment (having dogs means have to be careful about toxic things). The other canister type mite application made things worse by just providing additional homes to the infestation. These on the other hand have (touch wood) provided the solution, spider mites no longer present on any of our indoor plants. Well done my predator mite friends feast well!

Not impressed
I bought these after finding that a couple of my plants had a few spider mites. I washed the leaves down with neem oil in water and then hung these everywhere as a preventive against any that I might have missed. I didn't see any of the predators exiting the packets and several of the plants in the group's gained a couple of spider mites. I eventually cut open a packet to have a closer look and despite using a decent magnifying glass could find no trace of anything moving at all. I bought enough to have 3/4 per plant and the spider mite invasion was very small so I am very disappointed they failed to make the slightest difference as I prefer natural prevention where possible and had high hopes for these.
