small flys on patio rose

Try using a solution of water and washing up liquid. I read this advice/answers from the good people on GOY and it works for me. I'm sure you can buy a lot of sprays from local gardening centres but try this first.

Yes, washing up liquid will work. As it's viscous, the 'fly' can't get a grip.

If however, you don't mind chemical solutions, then there are many sprays out there. I use 'Roseclear' for my roses and it always sorts them out. It's a systemic spray, so gets right through to the roots and kills the bugs straight away and any new ones that chance their luck too.

all my roses are having the smae problem so have been letting my lil girl do as i did with my mums roses
spraying soapy water.

Water and squidging by hand is what I do then wait for ladybird larvae to come and much any left over. The problem with chemicals is that they kill the baddies and the goodies too. If you can be a little patient, I am certain natural predators will help you out!

A non chemical spray, if you're interested, is Seaweed solution. Pests detest the taste of it.
