    Please can someone help. I've came into greenhouse this afternoon for to see the windows with little white flies all over the place. There are loads and I'm worried about my plants.

      Hi,

      Do they look like either of these, the first are true whitefly, the second are more generally referred to as Aphids/Greenfly which can be almost any colour. green ,black clear etc.

      If they are all over the greenhouse I would first spray them off with a hose pipe on a gentle mist or shower setting.

      Same with the plants use a hand sprayer with room temp water so you do not shock them as a cold hose pipe would or run your fingers over the leaves to knock them off /squash them.

      You can get buy sprays that are safe for use on edibles, or make your own safe soap based ones.

      The yellow sticky cards help reduce normal amounts but seems this year they are coming around in plague proportions.

      They are not white fly, more probably shed skins of aphids.:smile:

      Managed to get this. There are loads so I washed the greenhouse down with washing up liquid and the hose pipe but they seem to be back in. Some were on backs of plants and look white. even the dead ones on floor look like white bits fluff. How on earth do I get rid of whatever they are.

      I've got Marigolds in greenhouse. I've checked the outside Courgette plants and they are literally covered on all 3 plants.

      Hi,

      Hard to say exactly what they are , seems there are some called Woolly Aphids which are what yours look like.

      If you google / ytube you will find some various methods to tackle them.



      They are unlikely to harm any of your larger plant in a few hours, but I would try and get them off the plants as in the next day or so before they breed.

      Please let us know how you get on as expect other may have the same problem with this warm weather.

      Good luck

        There was one flying about at my local GC, I chased after it and caught it, looked just like the one in ricky's video.

            I've just used hot water and fairy liquid on them. Just hoping it works as there were loads of them in the soil next to Courgettes.

              Looks like woolley aphid to me. I get them but don't like to use poison of any description so I rub them off by hand or spray with diluted Fairy liquid.

              Sure there are lots of bug poisons that will get rid of them if you are that way.Good luck, they really are a pest.
