    thats interesting will try that one if they persist ... thank you partridge I realised that although Green houses like moisture so do the pests

    Do you all throw water on the concrete ground in your Green house to keep it at a good moisture level in the sun ?? This was a tip I heard

    Spraying the floor will keep up humidity levels, keeping a watering can full in there will also help with humidity.

    After trying lots of different methods of trying to get rid of these pests, I've finally found something that worked for me ( and other people who've tried it )

    I put an inch deep layer of vermiculite on top of the soil in the pots and hung a sticky trap near the plants to catch the active flies, they take about two weeks to clear altogether using this method so be patient.

    I believe this works because the flies don't lay their eggs in the vermiculite and they don't dig through it to the soil.


  • Is this for fungus gnats Lurex? 

    Great to be able to deter them image

  • i have been given some seeds to a plant called "the shoofly plant" and i have been toldif you grow one in yr greenhouse it keeps them away. hence the name.. i will be tryingthis out next year.. i have seeds if nayone wants some.

  • ah that sounds amazing! hate those little things! always chomping on my nasturtiums! Let me know if it works at all! I've started trying to plant just any carniverous plant to try and keep thier numbers down... not too much success with that yet though.
