    Question Little Black Flys (fungus gnats) and Springtails

    Hello All,
    We have been double attacked by pests, luckily we think we have a positive identification using our handy dandy microscope. we believe that they are Fungus Gnats and Springtails. any advice on how they can damage the plants would be greatly appreciated, looking for more information/advice on each as far as control, termination, and effect on the plants and flowers. we have not started flowering yet and are in veg Pics below are from the microscope.
    thanks

    mason jar half full of apple cider vinegar and a squirt of dish soap, couple of yellow/blue sticky traps taped round the top to attract em in.

    Springtails won't do much damage, they eat dead and decaying organic material. And the biggest issue with adult fungus gnats is the faeces they leave behind on the plants Larvae will eat roots and can become an issue if left uncontrolled.

    Another option is buy an electric fly zapper and drop it in ya tent with the lights off for an hour


    For the ones already in the soil, Diatomaceous earth sprinkled lightly on top of the pot will help.

    NO SELL, NO SMELL, NO TELL!!!

    You must be a surgeon with hands that steady. Sheesh!

    "Fungus gnats are the worst", he said squishing one on his monitor.

    May want to run a couple rounds of nematodes through the soil. You can only get rid of fungus gnats by breaking their cycle. The stickies work for sure. Nematoads seem to work if you repeatedly treat the medium, definitely not a one and done. Aside from that... I think I'm going to go out and buy a bug zapper today. Mac is full of good ideas.

    Some growers opt to cover their pots in sand. Makes it impossible for the gnats to get out and then back in. Seriously, watching them struggle on the surface of sand is cathartic. Lil bastids.

    Mosquito bits. Follow the instructions to make a tea and water into the soil. 2 applications and i am seeing a 90% reduction. The fungus gnat larvae can slow a plants growth. They can completely kill new seedlings.
