Spider mites on cactus, echeveria and aloe

I check my plants everyday and up until 3 days ago I started seeing fine spider webs between the leaves. I didn’t suspect anything until today when I saw tiny bite marks on some of the leaves. How do I get rid of them for good before the infestation gets really bad and ends up killing my plants?

    They can be tricky to shift as they like a dry warm atmosphere - as do cacti.

    An extract from the RHS website - 
    • The systemic neonicotinoid pesticide acetamiprid (e.g. Bug Clear Ultra) is available for use on ornamental plants and some listed edible plants. Check the label for details and ensure that instructions are followed regarding maximum number of applications and harvest interval
    If you choose to spray with the above, best to do it late in the evening when bees etc have gone to bed

    Acetamiprid is pretty nasty stuff, not as bad as some neonics but all pesicides should be a last resort for gardeners.

    Thanks for the article, although the toxicity of this pesticide is low and is not carcinogenic so I’m willing to at least try it out.

    Thanks for this. I don’t want to take any chances this time as I lost 6 cacti a couple of years ago due to an infestation of both mealy bugs and white spider mites that I couldn’t shift.
