I fill a container with a cup of vinegar and a spoonful of dawn dish soap. It works pretty well but my hose stinks like vinegar.
When I bring my plants indoors in late fall, I group them under lights ,in a cool room in the basement. I than fill 3 or 4 empty margarine containers with water and space them around the plants on the table. I water the plants very sparingly all winter. These pesky creatures love water. These margarine containers become their source of water, where they congregate and drown. Keep the containers filled with water to the very top at all times.
I have gnats on my indoor ivy and have been spraying it with insecticidal soap, but I found one on the top of my coffeemaker. Is there any homemade ways to get rid of the darn things?

Are you absolutely sure the gnats are from the plant? Sometimes what looks like fungus gnats come in through the drains, not the plants.
My mom told me to mix water, dish soap and lemon juice into a spray bottle and spray my plant's leaves, top and bottom, and also water them with this mixture to get rid of gnats and/or fruit spiders. I love my plants and many of them are too large or have very long vines to re-pot them to help solve the problem since both my husband and I both have seriously bad back problems.
Do you think it will hurt my plants? I love my plants, each one has either been a present from my husband on a special occasion or gifts from our daughter on mother's day or birthdays so to lose one would feel almost unbearable. Please tell me if this will work, I am hoping it will as we are also Retired Air Force and money is tight. Thanks for helping and God Bless.

Make sure that your dish soap is one of the very mildest-in other words, don't use anything marked 'concentrated grease relief', or as containing bleach or OxyClean type stuff.
Ivory dishwashing soap was the best thing, we Master Gardeners (university extension service training, repaid by doing volunteer work in the community) used it for years as a safe pesticide (mixed with water) but then the company changed it's formula, and now I'm not sure if it's still safe.
If your soap is VERY mild, go ahead and try the homemade pesticide on a weed, lol, and see what happens. If it's still alive in four or five days you are probably safe to try the home mix on your more precious plants.
How can I get rid of gnats! I have a lot of indoor plants and all of a sudden I am plagued by gnats. Have tried a mixture of cornmeal and water but can't get rid of them completely. I don't know if I have used the cornmeal properly. HELP!
If you have fruit flies, put all fruit and moist food away in fridge. Garbage goes outside or gets 100% covered. Lots of fruit flies...vacuum the kitchen, suck them into the hose, gone! Good luck! PS what on earth is the cornmeal/water mixture for? The gnats would love it wouldn't they? Did you put it on the soil or what? (11/15/2004)

I have problems with gnats (I think that is what they are). I've noticed them throughout the house and they are coming from my plants. What can I do to get rid of them. Should I re-pot them? Thanks for any suggestions.

The vinegar in a water bottle with a paper funnel will eliminate many of them, but the problem is that they lay eggs before capture and will still thrive. It really just "lessons" their numbers. Cut garlic works at keeping them aways from things (damp soil/fruit) where they will lay eggs. Someone told me to try fresh orange peels, but I haven't tried it yet. The smell will attract them but the oil in the peel will kill the eggs. You have to make sure there is no fruit on the peel at all-so they said.
With potting soil for the indoor gardener-you have to bake it in the oven. I dump the bag or part of it-depending on the size into a large stainless steel bowl and bake it at 200 degrees for 30-45 min stirring it 1 or 2 X's. This ALWAYS works. Store bought soil will 100% of the time have eggs in it unless it is labeled sterilized.
The drain is the easiest-take some shaving cream or hair foam and spray it into the little vent hole in the top part of your sink while the drain is closed. This is a famous little hive for them. It is damp and only air passes through it. The tub really never gives them time without running water to get their eggs lain and hatched.
When bringing plants indoors for the winter I use a modest windex on the plant and soil. It also contains ammonia which can benefit green plants. It isn't something to do on a continuous basis. It is mild, doesn't harm any plant I've done it to and always eliminated the bugs. You may want to try it on a plant you're not greatly attached to-I wouldn't want to be responsible for any losses. As you might have guessed by now, I have been dealing with these "brats" for years-I haven't won the war, but I am staying a little bit ahead of them---finally! Thanks! Tim (03/13/2008)
I don't know if it will solve my gnat problem or not. I just re-potted them today. Time will tell. (It may be food to them, Ha!) I have already ridded my plants of quite a few of them by scooping that layer off. Anyway, good luck to all and if anyone figures it out please, do tell! Thanks. (04/18/2008)

I recently purchased four beautiful Massangeana Cane plants from Lowe's and some good potting soil. I potted my plants in nice planters and within a week there are millions of gnats crawling out of the soil and flying everywhere. I just purchased Knock-Out Gnat from Gardensalive.com and waiting for its arrival. Hopefully it works but in the meantime, is there anything I can do to get rid of these pests?

Almost everyone who grows houseplants has experienced these little black gnats. They are called fungus gnats. They inhabit the fungus and decaying plant material found at the base of houseplants. The fungus gnat's lifespan is as follows:
Adults live about 7 to 10 days and deposit eggs on or in moist soil. The females lay from 100 to 300 eggs in batches of 2 to 30 each in soil containing decaying organic matter. The eggs hatch in 4 to 6 days and the larvae feed for 12 to 14 days. The pupal stage is about 5 to 6 days before adults emerge. Repeat.
The adult gnats are an annoyance, but they won't hurt your plants. The larvae, however, can damage the feeder roots and root hair causing a general loss of vigor to some plants. The best way to prevent fungus gnats is to use a sterile potting soil mix when re-potting (one that is free of bark chips) and to make sure your pots have good drainage. These guys need a moist environment to feed and continue breeding. So if possible, it's a good idea to let the surface of the soil dry out as much as you can (without injuring the plants) between watering. This works well to kill the larvae.
Here are some other things to try:

River city, wickedly humid. I've used diatomaceous earth (D.E.) with lasting success for some time. Think of it like inhaling powdered glass, sprinkling powdered glass on your corn flakes.
Not very 'humane', but it does make short shrift of the little vermin. For my indoor trees, Potassium permanganate ( @pharmacist: It's for my citrus plants! Would this face lie? ) kills fungus. Soil fungus+Trees in poor soil=good thing --usually, but I do use it on plants subject to root-rot, once in a while. It's inexpensive, very little is needed and it works fast. And environmentally safer than detergents when used on its own. No household cleaners, bleach.
On the other hand, D.E. is excellent on orchids, since their fungal 'partner' is selective, and vital. Potassium permanganate breaks down quickly into non-toxic salts, utilized in by the plant.(as Na, oxides) -- Not for foliage.
Soap: mycelium (living fungus) is usually a waxy/greasy kind of business in peat, soaps like 'Safers' are OK for control. I've used dish soap which is a little harder-hitting. Problem is that permanganate soaps really aren't very picky, and most fungi, even if they're not feeding the plant directly, help keep clean water in the soil. Bacteria, small insects, fungus are all fair game to detergents.
D.E. doesn't change soil Ph. It is inert, like sand, only much finer. Neighbours with houseplants. That neighbour you just can not relate to? Just because gnats can't spawn in your pots anymore, that won't keep them from trying. And I guess it wouldn't be 'acceptable behaviour' to sticky-trap a few doors and windows shut. What-to-do. Or maybe it's just this darn humidity. Maybe gnats would go away on their own, or maybe green thumbs just wouldn't be as irritable. Thanks for some good tips posted, happy hunting! (09/06/2008)

We just had this problem, I bought my dad house plants for Christmas, completely re-did his living room. It looked great, until we started getting gnats everywhere. Thank you everyone for letting me know what was doing it, we just put our plants outside and will be working on DE-GNATTING them.
Here's some advice for those of you with gas heaters. We have several gas heaters, and since it's winter time we've been using them. I noticed today while turning one on about 16 gnats dead on top of it. On the ground underneath it were tons more dead gnats. So we have our own gnat killers. We're trying the ACV trick too, just to make sure. (02/08/2009)
