Flies all over shrub bush

Hello I was wondering if someone could advice why one of shrub plants is full of flies, some of the flies seem to have green on there backs some are just big black flies and there’s some wasps as well we can’t see any thing under the bush we just don’t know why there are some many flies is there something I could spray them with as I don’t really want to remove the plant as it’s been there along time
Thank you

 

Do you know the name of the shrub @Madgeanne ? Or are you able to upload a photo?

 

This is a picture I’m not sure the of name it as grown some over the years and I don’t really want to dig it up
Thank you

 

My guess would be aphids or scale insect, they both secrete a sticky substance that other isects feed on, usually its ants, but wasps do do the same.
Have a close look at the leaves /stems, and see if they are sticky.

 

Not sure if that's a euonymus but I remember many years ago a friend had similar on his ivy and if i remember rightly it was cluster flies.

 

There seems more flies than wasps do any of you know if I could spray the bushes with something or will the flies just disappear

 

Have you tried a hosepipe?

 

I did spray it with water but they just came back they seem to be there all day

 

Sorry to be a pest myself but would it be possible to take a pic of the flies on the shrub and are they doing any damage to your shrub? If we can see what they are then i think there will be people better to advise you than me.

 

I will try to take some pictures tomorrow

 

Thanks Marley Farley I will give the peppermint oil a try
