Summit 116-12 Quick Kill Mosquito Bits, 8-Ounce

I bought this because i heard it was great for fungus gnats and I previously tried everything with no luck. I have 8 plants and 7 had a gnat problemThere are a two methods to use:1- place a layer on top of the soil and water so it can penetrate the soil2- soak in water and use that water to water the soil.I used option 1 and noticed it slowly started to create mould, looking this up showed me it was normal. I left it for just under 2 weeks. There were still a few gnats though.After it was fully mouldy seen in the first pic, I used gloves to remove all the mould and a bit of top layer soil. Then I covered it with some stones that I purchased from the range. Since then i haven’t seen a single gnat around any of my plants

Worked really well getting rid of my fungus gnats infestation. After planting many seedlings i belive they came from some compost id used, due to a alot top surface water (growing seedlings) i was infested within 4 weeks. Used neem oil and tried bottom watering but due to cool weather and seedlings couldnt keep things super dry. Used along side some yellow fly traps. I'd say after 1 treatment reduce the flies by 99%. After 2nd treatment id reckon they will be done for definate. After 1 week there's an odd fly around that's avoided the traps. So a second dose should clear it all up. Advice for others would be take action as soon as u see these flies.

I have a serious fungus gnat problem (we live near quite a damp park and I have 50 tropical plants). I’ve been using these mosquito bits consistently for a few weeks now and they do help to reduce fungus gnats. However, they don’t do it 100% - they’re best used as part of a hybrid method approach - with yellow sticky traps and a spray. The size of the pack is ok, maybe slightly small for the price, but not daylight robbery by any means.That said, I have repurchased these a few times as I find them better than other solutions. They are easy to use (soak in water for 30 minutes to an hour and then drain them out - do NOT leave them sitting in water for ages as they will start to smell pretty bad).

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.

First point: instructions are not the best. Measurements are US. As far as i figure for UK, 4 US tablespoons equals 60ml… and one US gallon is 3.8LThere is no guidance on how much mixed solution to apply. I soaked my pots, which is ironic as this is the last thing you need for FN!!Soooo… second packet later, many repottings,(PS- sterilise your compost first - i microwave mine on high !! And wash old compost off roots then soak bare roots in super strong mosquito bits solution before repotting) about the eighth week of ‘soaking’ the pots with solution and loads of sticky traps i might be winning. Either way i’m not applying any more or the plants will die if root rot. I think it helps, but i needed to use other measures too and keep reapplying!!!Will try nematodes next if the problem resurges
