If you go read about them you'll find out they breed and live in your drains and houseplants. I put all my plants outside too, just in case they were in them too.
Now when you thinking about these flies and how they breed and live, I had to tell myself to cut off how they breed and it might help. So I went and bought plugs for every drain in my house, even for the bathtub. If you get them at the Dollar Store there pretty cheap.
I also taped an old cut up sock around the washing machine drain to keep them out of there too. Be sure not to block off all the air to this drain as it will not drain without air being able to go in. That's why I used the old sock, it still lets air in for it to drain right.
I plugged up all the drains and kept them plugged all the time. If you look at the picture, I always leave water in the sink with the plug in to make sure they can't go around the plugs too. If I needed the sink for something, I always put about 4-5 inches of hot tap water in the sink before I unplugged the sink for use. This will wash down the drain any flies that hatched while the sink drain was plugged. Then I always remembered to plug it back up.
I did this for around 3 months or so, because most of the ones flying around died after a month or so. But I kept the drain plugs in, and still do today, just in case. They couldn't breed so they all went away after that.
So think about it. If they can't breed they can't come back. This worked for me, hope it helps you guys too. Thanks for reading this.

If fungus gnats are a problem with your houseplants here is an easy solution that has worked for me every time. Fungus gnats lay their eggs and develop into adults in the top 1/2 inch of the soil and they need moisture to survive.

Does my Spider plant soil have fungus gnats? After watering my indoor potted plants, within about 36 hours, I noticed a soil surface infestation of what looks to be fungus gnat larvae. A large number of the larvae look like whitish thin worms from 1/4 in. to 1/2 in. long. I wasn't able to see the notorious black tip on the end of the body. The rest are about the size of a nail head with 6 legs and antenna.
Also I am finding a number of what looks like large eggs, about 3/16 in. diameter from God knows what insect species. They are yellowish to amber in color with watery yellowish goo inside and a thin brittle clear shell. What the heck could they be? Aliens? Am I wrong about the fungus gnats? Any suggestions? Help!
EWW! I would take the spider plant out of the soil, shake the roots gently, wash in warm water carefully. I would use new potting soil that has been microwaved for about 30 seconds or so to kill any critters..let it cool for a few minutes. Then replant the spiderplant in the soil, and spray the spider plant with water with a small amount of dishwashing detergent to keep off bugs.
Absolutely, change out that soil! If you can afford it buy new soil.
Spider plants are really easy to propagate. Cut off some of the runners and root them in other soil just in case it does not take well to the soil-switch!
You can also give your plant out of the pot a bleach rinse, 1 TB to 1 gal of water. THEN get new soil. AND bleach your pots to kill any residue. Anytime you bring in plants in the fall from outside, seal them in a large plastic bag, spray some house/plant spray which will kill friends brought it. Must leave the plant in bag a couple days--read instructions.
I am so sorry I have nothing helpful to say...I just had to say, eww
Pour cold tea onto your plants. This acts as an insecticide! Good luck
It might be something called scale. If the outside of the pot is sticky and the plant has a sticky residue, then this is the likely culprit. You can save the plant by spraying it with an insectide and then repeating it in a week. Look online for pictures. Make sure to isolate the affected plant from any others in the house until it is cleared. I have saved several plants from this problem Good Luck.
How do I get rid of household gnats in potting soil?
By Tammy from VT
I have this problem no matter how many times I've changed the soil. I have no solution as of this date.
After you repot in clean soil, you might add a thin layer of sand to help keep them from getting to the potting soil. Best to use a growing sand that will be salt free.. a fast remedy is to mix up any liquid insecticide that is safe for the plant, even diluted down a couple of times and then use this mixture to water the plant, this will kill the larvae in the wet soil.
Those are fungus gnats, and they are difficult to get rid of completely. Thankfully they seldom really harm the plants, though they are a real nuisance. In addition to the tips below, hanging a sticky fly strip near your plants will trap a lot of them. Another tip I have seen is to put raw potato cubes near your plants and change them every three days. I think they are supposed to lay their eggs there instead of in the soil. (The worst infestation I ever had was when I had a 50 lb bag of potatoes near my plant lights in the basement, and there was a bad potato near the bottom that I didn't find for some time, so I guess they really like potatoes.)
I was looking for a solution to my gnat problem. I opened a brand new bag of potting soil for some seedlings, and gnats came swarming out of the bag. I talked to my Aunt who has worked at a florist for years and said they microwave their soil for a few minutes and let it cool down before planting. It kills the larvae. Be careful, microwaving for too long can cause the soil to catch fire. Also the house will get a woodsy smell to it after doing this, she suggested microwaving some lemon juice to get rid of the smell.
First I soak planters in mild chlorine bleach then rinse. This water is poured over the gravel walk behind house and kills the moss/mold on pavement. We have plants lining walk and this has never bothered plants.
I have problems with soil gnats every year when I bring my household plants back into house after they've lived outside, plus, I have 3 cats. Finally found a solution ~5 yrs ago and works every time.
After repotting, add a thin layer of larger particle activated charcoal (can get at pet/fish shop) just on top of the soil. I then cover this with plastic mulch - some colors like blue or yellow enhance the colors of the plant. My favorite is blue, the green plants and/or pink blooms seem more vibrant.
The charcoal takes care of the gnats (as I've read they like moist soil) and the cats won't disturb the plastic mulch. If you have really large planters, I'd try the volcanic rocks that you might use for landscaping or grills. Had these in some really large planters with taller inside bushes. Cat could get into planter, but, jumped out quickly when she touched the rock.
Happy indoor planting !!
What are the little gnats in my potting soil?
Does anyone have a solution for getting these pests out of your house plants? I've used every solution posted for eliminating potential breeding grounds (and the flies themselves), but no one has touched on how to do this short of throwing away my plants.

I have been having a problem with fungus gnats in and around my potted plants. I was told that if I diluted regular Listerine, 1 to 1 with water and spayed the organic soil mixture, the solution, would kill fungus gnats and their eggs that live in the manure.
If anyone knows this to be true please give feed back. Have tried other solutions, but to no avail.

To break the cycle of the fungus gnat you need to get rid of the larvae. It's very simple and easy. A slice of potato is all you need. Simply lay the slice on the soil of infested plants and the little maggots can't resist it. They begin feeding in the slice and now you have them where you want them. Throw the slice away after about 3 or 4 days and replace as needed. Of course there are other ways and this article may help. But making sure it's fungus gnats is key here because this trick won't work on other types. Hope this helps.
I have a fungus on my grass. I had a commercial service which I gave up on it and after that is when I got this fungus. It seems the grass is very weak do to all the chemicals this company laid on it and the fungus just took over. Any suggestion on a natural product, I'm afraid to use any more chemicals. Thank you.

You might want to change your pH. I'd call or go in to a local plant Nursery. Look in your yellow pages or Google "Plant Nursery & your City & State" & I bet they'll have lots of natural products. They may even be able to help you over the phone. You'll need someone who knows about Florida specific soil. If I remember (from when I was young & lived there) Florida has sand & not dirt for soil. Also, because it's "Tropical" I bet there's a lot of people with fungus in their grass. Call a local Plant Nursery & ask when the horticulturist that works there will be in.
* Don't use Vinegar, because it will kill your grass. You'd have to dilute it a WHOLE lot!
Beer on a day when its not going rain for a few days. The yeast in the beer will eat the fungus.
How do I get rid of little flying black bugs that seem to be in my potting soil? Where are they coming from?
Actually spoke to miracle grow and they said it is common with the potting soil and they are harmless. I've never seen them before this winter. The rep I spoke to said that I could put a layer of sand and that will kill the larvae. I also had to put the UPC code in an envelope to mail it back to them for a refund.
I have had my fiddle leaf plant for several years. How do I get rid of the tiny bugs everywhere?
What can we use to rid ourselves of these gnats? I sprayed throughout the house with HotShot and it worked a little. I don't know if they were all asleep or just hiding away. They're everywhere. Thanks for your help. God bless.
Fungus gnats are in my closed top terrariums. I have tried every method that I have found on line (yellow paper with fly strips, and I have killed a lot, but not all). I found out that plants brought inside can have them so I took them all out on the front porch and put sand in the top. I discontinued watering on top and put a tray under them to water. (Someone suggested vinegar and that works.) I also put my potting soil in the freezer. I haven't put it in bake yet but will try. I have reworked four, washing the soil completely off roots, and cleansing the jars and rocks. After reworking two recently, one of them I discovered has a few gnats. I haven't tried insecticides because I had planned to sell them, but until I solve the problem completely, that's out. Help! I am working hard and everything works but not completely. If insecticides are used, do I spray the soil or all the plants?
Is there any way to get rid of gnats and larva in my new terrarium or do I have to dump all of the soil, rinse the plant roots and start over?

How do I get rid of little flying black bugs that seem to be in my potting soil? Where are they coming from?
I have at least 50 houseplants. I re-potted many over the years and have never had a problem with gnats, now I do. I try to let the soil dry out as much as I can without harming the plants.
