Just spray with water JAMES.
red spider likes hot dry conditions.......when you experience these conditions soray with a hose and remember to get hose inside the conifer
i learned this the hard way....one conifer esp, picea Albertiana is prone to mites and I was fast losing mine. Regular spraying was fhe answer.
i really wouldnt use an insecticide....sorry Gertie.....esp if they are of decent size. Not necessary and a risk to your lungs.
possibly a little late now but if we do get a dry warm session get out your hosepipe
