    I all ready have the little bastards everywhere... came with the MG I used last time. Now I have some Fox Farm or Black Gold EWC that have added some other crawlies to my seedlings all ready.....
    1/4 tsp ontop of a pot of soil is enough!

    One dunk treats like a whole olympic sized swimming pool for mosquitoes... for like 3 months if I remember the directions...

    don't get carried away!

    Thanks Ya'll!!! Glad to help. I just could not find any information on the subject when I was researching it.

    This product was not intended for fungus gnats, but works great! It makes sense, since Gnatrol is the the same product, different form, and harder to use.

    Just got a catalog from Planet Natural... hahaha they think I will give them more money for their dead useless predator mites.. no way.. hahaha

    i add gnatrol wdg to my res/watering can whenever i introduce new media into my garden with the exception of hydroton and rockwool minicubes... coco/dirt/etc all get watered with it the first time they get watered to help kill any eggs along for the ride; i follow up the second and third waterings with gnatrol as well... this is enough to kill em

    for seedlings i pasteurize my coco in a 5gal bucket with boiling water poured over a good amount tied up in a paint strainer bag left to sit for 90 minutes. this sterilizes the medium; nothing is alive inside it; i only do this with coco as there is no bioherd to worry about out of the bag... nothing worse than gnat larva crawling around a 20 dollar seedling

    Gardeners put a one inch chunk of potato on the compost to check for larvae. just like lifting a stone in your garden, if it's damp under the potato larvae will come to the surface. if you see no sign of life then you can say your soil is pretty clean.

    I have always used dunks for many many years now It works great I also use the bits the bits work faster but the dunks are stronger so it seems after about 4-6 days no more gnats simple to use and works awesome......ST

    oh, I get it, the adults are gonna lay eggs on the tater? sounds messy and time consuming. I would not want to encourage molds to grow in my grow?? just my 2 cents.

    I use Miracle Grow soil, and it has free fungus gnats in every bag!! But I left it in the trunk of the car and let it get really really cold. But that is all I am willing to do. I am just plain lazy.

    That's why I like the dunks. EZ to use, low maintenance method. It will kill all the larva so eventually no more adults.

    Thanks LolaGal for the welcome
    I Just nuke a small amount to top up, and for fresh cuttings now, so it's no longer hard work

    I am way to lazy to microwave my dirt, but good idea.

    I just throw a little dunk on top of all new dirt, as a preventative measure, no gnats here! (or mosquitoes lol)

    I crumbled some up on my soil plants, I only found one gnat ( which I promptly dispatched), so I'll be looking out for larva. I'll put down a little potato after I've watered once or twice.
    I'll keep you posted on how they work!

    Yup, that is the same one I used! Thanks for posting. I was curious.

    I wonder if there is also a shelf life on them?

    What brand did you use? I am curious! No gnats here for me. I like doing research on this subject. thanks
    This brand from Lowe's. Is it the right one?
    Thanks Lola

    Hi there guys! I’m new to “Tomato” Cough! Growing and this is my first post.
    I have had a bad time with Fungus Gnats too. I’m sure they came in the compost bought from a local garden centre and exploded into life in the veg room, weakening plants and making it hard to take cuttings.
    Thanks LolaGal I like the Idea of the Mosquito dunks crushed and sprinkled over the soil and watered in. If only I had heard of these and Gnatrol a few months ago.
    I did a fair bit of research on FG’s and hope this helps you guys.
    The adults live 7 to 10 days and lay their eggs on moist soil surface. Females lay up to 100 to 300 eggs in batches of 2 to 30 each in decaying organic matter. Eggs hatch in 4 to 6 days; larvae feed for 12 to 14 days. The pupa stage is about 5 to 6 days. 35 days from egg to dead.
    Plant damage symptoms appear as unexpected wilting, low vigour, poor growth, leaves yellowing and defoliation.
    They can be controlled by the Predatory mite, Hypoaspis miles. The H. miles, is a voracious predator of mites and insects that spend most part of their life cycle in the soil, including Gnat larvae and pupae of thrips. Once introduced, H. miles usually can reproduce and establish.
    First, prevention should be your goal, and this is to avoid over watering, especially in high organic soils.
    Adults are attracted to bright lights, mainly in the blue spectrum like PL’s and fluorescent,
    If you are having problem with FG’s in a hydro set up? Then I would suggest looking elsewhere for any infestation. House plants or mothers if in compost, hydro and compost grow in the same room, or even areas in the garden which might be a breeding ground. Fungus Gnats need a damp soil/compost medium to lay their eggs. It’s the hot, humid and bright condition attracting the adults to a hydro only set up. Using Mosquito dunks in a hydro set up is ineffective at best for killing Gnat lava.
    I managed to wipe out my infestation by covering my pots with clingfilm which can be lifted for watering, but stop the females from getting to the soil to lay their eggs, and thus break’s the life cycle. I also microwave any new compost before using it. This seems to have worked, not seem a gnat for a few weeks now... fingers crossed.
    If... or when I get them again I’ll give the Gnatrol or Mosquito dunks ago.
