Mosquito Dunks 116-12 240ml Quick Kill Mosquito Bits

I've learned much more about fungus gnats (sciarid flies) than I ever wanted to. Where do they come from? In my case, they were flitting in through an open window. But they can hitch a ride on anything that has soil. I've even spotted them around potted live herbs sold at my supermarket. The adults are teeny little suckers, but they can swoop in and drop a load of gnat eggs in a second--producing over 200 eggs in their short 2-week adult lifespan. If any of those eggs end up in your houseplant soil, you have a houseplant infested with gnat larvae (like minuscule maggots). They wriggle around in the soil, ravenously eating anything they can: fungus obviously--as their name implies--but also the delicate root tips of your poor plant! When the larvae are well-fed and ready, they pupate into adults, and the Circle of Life starts all over again, much to your horror. I wasted time trying a long series of mild and ineffective home remedies. Cinnamon? These bugs just yawned at the stuff. Neem oil? It made my sitting room smell like burnt tires, but the gnats weren't bothered a bit. Drying out the soil? This may be the worst thing you can do; as soon as the fungus dries up, those hungry larvae move on to the next available food source: the juicy, tender plant roots. Don't waste time on any of that. Sticky tape and cinnamon are not going to help you in a war situation. This product is more like a biological warfare agent on the gnat battlefield. No, literally, it is a bag of dried plant bits soaked in bacteria (Bacillus thuringiensis subspecies), which is lethal to the gnat larvae. Read the directions on the bag; they are very clear and easy to follow. You soak the dried plant bits in warm water to release and revive the bacteria; then, pour the resulting bacteria broth into the soil. The bacteria infects the larvae, and they die. This breaks the life cycle, so fewer adults will emerge from the soil after about a week. Don't let up, though; the adults still flying around are not affected by the bacteria, so they will still be busy dropping fresh batches of eggs. Hold your nerve and treat the soil again every week for about three or four weeks. By then, all the adults will have all died off (from old age), and any eggs left will have hatched, and any larvae will have become infected. It's not an instant solution by any means, but it is the only thing that actually works. I plan to keep treating my plants once a month or so from now on--the bacteria is harmless to the plants (and anything else that is not a gnat larvae), and you never know when one of those gnats might sneak in from outside or on a newly-bought plant friend.

Ottimo prodotto, usato in combinazione con https://www.amazon.it/PROTECT-HOME-Cyperbase-Insetticida-Concentrato/dp/B093LTYWHH Ho comprato dei secchi con coperchio di plastica nera, riempito fino a 1/3 di acqua con un po' di sapone per piatti e sfalcio di erba, un po' di questi granuli e ho installato 3 viti M4x50 sul bordo del secchio per mantenere sollevato il coperchio. Questa è la trappola che ho costruito. Ne ho costruite due: una con poca erba per la tigre e una con acqua più sporca per le marroni classiche. Le due trappole le ho installate sotto due piante cespugli in giardino. Già prima dell'integrazione con l'altro prodotto, in circa 2 settimane ho visto un calo delle zanzare.

I use this mixed with water to prevent fungus gnats, it definitely works. I mix it right in with the water for 39 minutes prior to watering it, I also put fertilizer in there at half strength and the plants are thriving, no pests

Good

Since using the population of fungus gnats has dropped. You have to be consistent with this and replace if you leave at the bottom of pots to bottom water as mine tends to mould but ultimately. Does it work. Yes. Stay consistent. Change your soil. Goodbye bugs.
