Why is my plum tree covered in flies and how can I get rid of them?

    Look like blue bottles and horse fly. I've had a good look around and can't see anything that would attract blue bottle.

    Still there 

  • Having googled the problem it's not uncommon but no body seems to have any reason why its happening.

    Do you have a recently landscaped garden nearby, a farm or a big pile of farmyard manure.

    Blue Bottles and horseflies etc occur where you have a large quantity of manure or decaying rotting vegetation or even worse meat or a carcase and the flies are sheltering in your tree.

    Are the plums rotting on the tree?

    Because of the volume of flies involved there doesn't seem to be an effective way of getting rid of them except wait until the problem resolves itself on its own whatever it may be that is causing it.

    If the plums are not rotting on the tree then I would look a little further afield for the root cause of the problem. Manure, Garbage, Composting bins, a dead carcase of an animal such as a dear or cow somewhere. Is your tree near a stream or river? Is there a carcase in this stream / river nearby.  A building site will buy in topsoil for the gardens, it may contain tens of thousands of fly grubs that are turning into flies.

    Just a few ideas, look a little further beyond your garden and the tree for the reason behind the problem.

    I had the same problem but I thought the flies looked greenish in colour?

    One of myneighbours said he thought it was blight and some body else said I should spray it with a mild solution of Jeyes fluid but I'm  a frightened to do this for fear of damaging the tree further. Any advice on this?

    forget Jeyes, it's not for plants and bad for wildlife.
    so there were flies, is that serious?

    They’re something for the birds to eat.  :D

    Jeyes Fluid is noxious stuff and as Nucutlet says it kills wildlife ... as well as cats and dogs ... and it’s a horrible painful death.  I’d never use it on a plant or tree.

    If you can't wait for them to buzz off or die naturally or be eaten by the birds try giving them a squirt from a hosepipe with a nozzle on the end to direct the water at them with a bit of force but without damaging the tree.

    I'm  not talking about a few flies, there wear 1000's. The whole tree was completely covered and the fruit was totally ruined.

    maybe harvest a little sooner? Spraying with Jeyes fluid would ruin the crop anyway, you couldn't eat it after that.
