A related product, "Guard'n'Aid for SpiderMite Concentrate", has pyrethrins (pyrethrum) as the active ingredient (and is x2 cheaper), and from https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6206511/ seems to have a similar action mode - have anyone tried it?

Checked some previously obviously infested cacti under the Microscope last week, everything still looks clear I would say that Killermite works.

Mites usually hibernate over the winter if plants are resting and then return (after a nice break) in the Spring.
I understand they can overwinter as eggs or as adults. I've watches adults 'parked up' for the winter lodged between tubercles - they don't move over winter and look dead. They are hard to find as using a lens- it is much easier to see one that is moving around. But then after the winter they start to move around again as if nothing has happened...

So it will be interesting what you see in the Spring when the plants warm up again. It would be really great if there was a product that could keep these pests away for a long time.

I use a different product with the same active. It is highly effective against red spider.
Be careful with dogs around this. The product I use carries a warning about toxicity to dogs, so ours are always kept inside the house when I’m using this.

So they might be hiding...

That's weird, another post arrived mid- type and I ended up with two posts with different edits.
I'm sure I couldn't repeat this if I tried.

I'll certainly check in Spring for signs of mite activity, probably periodically before then.
The infestation I had was Brevipalpus mites as opposed to the two spot RSM, apparently they doore damage and there are no web signs.
I check under a microscope and seen moving mites and red stationary eggs. Post treatment the mites are gone and some eggs remain visible, hopefully dead.
I'll try to attach a picture for reference.

The other thing to remember about Brevipalpus mites is they reproduce very slowly compared to Two spotted mite. This makes it hard to determine if you have successfully eradicated them

I didn't know that, all the more reason then for regular checks.
Compared with the photos attached the latest check was clear of any signs except what I take to be egg remnants, nothing moving.

Would Killermite kill mealy bugs?
