Ceylon Cinnamon and Fungus Gnats

8 years ago

Took a leaf tray into the kitchen this morning to check them. As I drizzled some water into a cup I saw a single gnat crawling on the soil and then

jump/fly to another. Recently read about using Ceylon cinnamon to get rid of them, and what do ya know...that gnat took off like a bat out of...soil. She's probably finding a home among one of my ripe tomatoes right now. Time will tell if it keeps her babies and buddies from this leaf tray, but I'm keeping the cinnamon handy just in case.

Anyone else have experience with trying Ceylon for F-gnats? Hydrogen peroxide solution to spray is supposed to be another natural remedy that works.

    Oh, I deal with them every year! So annoying. I have other big plants in the house. I put up yellow sticker around all the plants. I used to use mosquito dunks in prior years but doesn't help. So I tried hydrogen peroxide last week. I' m waiting to see the result.

    So you sprinkled the cinnamon on top of the soil? Let us know if it works well for you after you give it some time to see. Sounds like an easy (and fragrant) solution!

    Wow, add a little sugar to that cinnamon and you can make cinnamon toast! Yes, I second what Anne says,,,,,let us know what happens. Rosie

    Buy a package of "Mosquito dunks" at the garden center. Put one
    quarter of one in your watering can. This will kill the larvae in the
    soil and stop future generations. It is all natural and safe. Use
    sticky traps and manually kill the adults.

    I can second the mosquito dunks. Work like a charm.

    I don't think I have an infestation yet but if I see more I will definitely try the dunks. My weapons arsenal keeps growing larger...

    Just remember it takes a few weeks for the future generations to be eliminated. It doesn't happen overnight. Keep using it even after the problem is solved.

    Just askin,,,,,,,would mosquito dunks be effective against mites? Rosie

  • 8 years ago

    No, Rosie. Completely different animal.

  • 8 years ago

    Well mites lay eggs that turn into larvae. And Mosquito dunks are a larvicide. So it WOULD kill future generations of mites.

    I know they are different Anne, but I was thinking at the end of the day, maybe,,,,just maybe,,,the dunk would be effective against more than one critter. Kind of like Raid,,,,,if it kills one bug it may kill a bunch more we don't know about.

    Maybe Tommyr is on to something?

    I don't know how expensive it is, but if it is not out of the ball park maybe a trial run would prove fruitful. Maybe??? Just my thoughts. And if it works that would be one more tool in the tool box we can use. Just trying to think outside the box. Rosie

    I tried to answer that question with research, Rosie. I found the quote that follows on The Green Blog, Green News from the UC Division of Agriculture and Natural Resources. Does it mean that it would work specifically on mite larvae? I do not know; remember that Tarsononemid mites are not "insects" but members of the Arachnid family. Mosquitoes are insects, as are flies. I keep coming back to information such as this: "Not every insecticide that kills roaches, spiders and ants will kill a mite. Even the pesticide sprays labeled for spraying mites will sometimes suppress the pest instead of killing it quickly. Products labeled for controlling mites usually have specific sites, locations or plants where they are allowed to be used."

    I would think in any case that alone, mosquito dunks would not be of any use in combating the adult mite population and so one would STILL need a miticide to treat the affected plants. But you could say that using this "tool" would certainly not do any harm. But would it help? I am doubtful.

    "Larvicides containing spores or metabolites of the bacterium Bacillus thuringiensis israelensis (Bti) (e.g., Mosquito Dunks, Mosquito Bits, Microbe-Lift, and other products) act as stomach poisons when ingested, killing larvae within a few days. Bti affects only fly larvae, so it won't harm predatory insects living in the pond or water feature. Another effective larvicide is the insect growth regulator (IGR) methoprene (e.g., Pre-strike Torpedos). IGRs interfere with larval molting and also take a few days to kill, but they have a broader spectrum of activity, affecting most juvenile insects and other arthropods that might be in the pond. Both Bti and methoprene are available as granules or pellets, remain effective for about a month, and as with all pesticides, should be used only according to label directions."

    You have really done the research. Thanks for the info. I guess I was "grabbing at straws". Rosie
