How to Use Apple Cider Vinegar to Stop Fungus Gnats in Vegetable & House Plants: Set Up Examples

Apple Cider Vinegar will attract fungus gnats and other flying insects and kill them. I show you how to use it, set up the saucers and where to place them. I also show you examples of the trapped fungus gnats. You can use this for flower and vegetable seed starts and for your house plants.

This is my first year growing plants from seed, and even though I had fungus gnats get into my greenhouse, your tips helped cut those numbers to almost nothing! Thankfully I have not lost a single plant to them, thanks to the combination of apple cider vinegar, the yellow sticky paper, letting the tops of the coco coir dry out, and a tiny garden spider living on one of my pepper plants. I actually have only lost a single plant from all my seedlings, and that was due to damping off on a plant that was weak to begin with, which I think is really good for my first attempt at seed starting!

Wow! Great video, hadn't seen this idea before. Perfect! Thanks

[PinkSlippers]

I am sowing seeds indoors for the first time, and so glad I watched your video on sterilizing the potting made 2 tubs of potting soil yesterday...8 parts peat, 1 part vermiculite, 1 part perlite, 1/2 parts sand, 1 tsp lime....then I boiled a huge pot of water and poured it on top and mixed it all in and put the lid on to cook it....Now I hope it works !

Thanks Gary, your peppers are looking good

[sherbrownsf]

Congratulations on subscribers you deserve it!

[heatherrinks]

Thank you for sharing this. I'm so grateful to have found my way to your channel. I'm new to gardening and your video's have helped me out so much. Again, Thank you and have a blessed day.

Gary this was the perfect length video all of your should be this length.

[Darnesha]

Thank u so much. I recently bought some apple cider vinegar to use around the house. I am so glad you shared this video because my house plants from Home Depot has those fungus signs on them.

[Gotchapic]

It works! I’ve used it since I began losing my seedlings indoor....

[renegadetherapist]

This stuff works!!! I have seen tiny bus walking around in the bottom of a plant saucer, took a pic and enlarged it and it was a baby gnat! Glad it was a gnat, I panicked at first, thought it was thrips or something worse LOL

[Littlewingwas]

Thank you. I'm finding loads of uses for vinegar, apple cider and white 🌼

Have you tried black coffee? That works really well too.
I water my plants with water infused with Mosquito Bits. I wrap a capful up in a coffee filter and twist tie it shut. Fill up your watering can and throw it in. I wait 1-2 days. Then water your plants.
I also sprinkle diatomaceous earth on top of the soil. When they walk or crawl through it, it cuts up their exoskeleton and they die.

I used a fly lamp, sticky paper and even fine sand on top of soil and now i have almost no fungus gnats left.
I tried to use apple vinegar, but they seem to be more attracted to stickypaper. nonetheless i also use apple cider just in case, because these flies multiply so fast, you have to indeed take action before it spreads out of control.

Great advice (solution) have a great day my FB friends.

[myrustygarden]

OMG your my hero they must have been in my compost and are killing my seedlings. Off we go to add apple cider pots. :O

[ewellacres]

I find using apple cider vinegar is one the the cheapest and most effective ways on the small scale hydroponics to controlling fungus nats. Not to mentions it is one of the most relatively available products at most groceries stores around.

[mnelson]

Mosquito dunks/bits are the trick to stop them once and for all. It's a form of BT bacteria that also consumes gnat larvae. That darn Miracle Grow potting soil ALWAYS has gnats in it haha

[WhatWeDoChannel]

What a great tip! I make similar traps from wine with vinegar added in the fall to control fruit flies in my winery. I always add a drop of liquid soap to break the surface tension of the liquid, do you think this would be a good idea for the vinegar traps too? I’m definitely going to employ your method for controlling fungus gnats this year!

Could these be the same gnats that are all over the leaves in my garden? If so, will this work outside? Down here in south Mississippi, I'm overrun with pestilence since July, so I've given up on most of the spring/summer plants and pulled them for compost. I've noticed a ton of sun leaves from tomatoes, potatoes and watermelon having grey/black marks. I found snails/slugs on some and assume it's that. I will never know how snails got onto my okra that's 6' high, but that's a mystery for another day. Anyway the last 2 weeks I finally saw the gnats all over the new leaves. I've let some of the tomatoes continue to shoot suckers to see what will happen and they love them. Along with the new potato growth.
