Red Spider Mites?

I put a spoonful of cooking oil and a spoonful of fairy liquid into a sprayer full of water today and gave the rose and the dahlia that was next to it a good soak. I also sprayed a couple of spare pepper plants to make sure that it doesn't hurt the plants, because there's some yellowing on all the peppers that I fear is down to the spiders as well.

If nothing dies in a few days I'll start regular repeat spraying and see what happens.

Did you have any success with this Martin?

Well, I think it helped. It didn't get rid of them altogether but as I recall the spread stopped.

I made the mistake of not cleaning out my sprayer afterwards and it took ages to unclog it next time I used it

The spiders haven't been nearly as bad in subsequent years. I just try to keep the humidity up on the cucumber plants because it seems they go for those first.
