Black clusters of aphid/fly

Hi all I have black clusters of fly/aphid on my plants especially my dahlia, just under the flower head on the stem. Will washing up liquid spray combat this? 


Hints pls. Thankyou

    You could try, never known it to really work though. Bug spray works, so does squashing them with your fingers but this is messy. image

    Blast them off with the jet from a hose, that's what I do image

    I do same as Paula until the ladybirds appear. Bit late this year image

    I'd do the same thing with a hose....but, I don't have that kind of luxury. Feel blessed people.

  • Washing up liquid on so let's see! Pests are a pest!!!

    yeah washing up liquid mixed with water in an old squirty bottle does the trick.. or just rub them off.

  • Trying the squirt and rub lets see how it goes - thanks
