Tip: Make A Gnat Trap

I also have a gnat problem again this year. The only thing that worked for me was to take a 9 oz. or larger glass, make a funnel out of paper (computer or notebook) with a tiny opening at bottom. Make the top (opening for gnat entrance) large enough to fit in the glass and use tape to hold it in place. I found they will find a way out if the bottom funnel hole is too large and or if the top part isn't taped securely around the glass. Funnel made from notebook paper.

Pour enough apple cider vinegar in glass (before adding funnel), to get it as close as possible to bottom of funnel. The smell of vinegar attracts them to the funnel and in they go and can't get out. You'll see them walking around inside the glass trying every way possible to get out. They'll get tired and drown in the apple cider vinegar. Place these where you see them the most, in the kitchen, bathroom, laundry room, etc. They like moist areas. Remember to redo every couple days. I tried plastic cups, but for some reason, they go to the glass better. Good luck!

Tip: Use Bleach Water to Control Gnats

Recently our house has been overrun with gnats. I followed all your suggestions, nothing worked. I finally called an exterminator, he couldn't come but he told us to pour scalding water down every drain in our house and follow it up with bleach.

They said we may have to do it several times before we can see it is effective. We used 2 gallons of scalding hot water for each drain and followed up with a quart of bleach for each drain. I wanted to pass this along cause it is really a problem this year.

Tip: Getting Rid of Gnats and Fruit Flies

Gnats and fruit flies love sweet liquids. You don't have to use wine, although they do like it. Add a few drops of dishwashing liquid (only about 3) to wine and slowly stir this makes a film on the surface that the bugs get trapped in.

I noticed I had a small gnat or fruit fly problem a few weeks back. I tried everything. Eventually I gave up and tried to cope with small traps here and there. Then one week I had a can of monster energy drink. I had one sip out of it before about 25 gnats swarmed it and were all over me. They really like Monster...lol. So I put the Monster into a wine bottle added a bit of dish soap, swished it slowly to mix and set it next to the litter box. Caught about 50 in 10 mins. Best of all Monster doesn't seem to rot or stink, so just scoop the bugs out and reuse for bait.

    Tip: White Vinegar for Gnats

    Everyone knows how annoying gnats can be. Once they are there, it's very hard to get rid of. They nest in damp places, such as sink drains. If you want to get rid of them pour a couple of tablespoons of white vinegar into a small bowl. Put it in the general area of where they are swarming.

    You can tell a difference within a day. They will be gone completely within a couple of days. If they are in more than one area, put a small bowl in each area. This really works!

    Tip: Bleach Drains for Gnats

    I have tried a lot of these tips. Honestly, the best way I have tried was bleach down the drain and the fly traps. I did the apple cider vinegar but it didn't work as well as all three of the combinations together.

    I had them really bad and they were the biting kind. I even have one stuck in between my computer screen so I have to look at this dead gnat every time I use my computer. Uuhhggg, they are a really bad nuisance this year!

      Tip: Create a Gnat Trap

      To create a gnat trap, take an empty 2 liter bottle, cut off the top 1/3, pour in some sweet pickle juice or vinegar/sugar combo, then invert the top and fit it into the bottom containing the mixture. It should attract the gnats which will then be unable to find their way back out!

      Tip: Homemade Gnat Trap

      This works. Forget dawn dish soap and whatever mixed with it, forget bug spray.

      Here it is.

      Take one of those little pre-made meals in a cup like, chicken ala king, chili, etc... with the 4 little holes in the plastic top. Eat the contents then rinse clean, including the lid. Inside the empty container, place some skins from an apple or cantaloupe. Fill it and put the plastic lid back on. Wait a few days or more and then tape the holes shut.

      Suggestion: don't open the lid for anything. They all fly out. I found that out. Believe me, they're in there.

      No more gnats. Works for me like a charm. Just started doing this over the weekend and I can't believe the difference in just a few days.

      With all the tomatoes, cucumbers and other produce I have in the house, it's a miracle. "Try it, you'll like it".

      I live in an area where there are gnats and no-seeums, both of which go after my dogs. I rub them down from head to toe with white vinegar. It even keeps the fleas and ticks away, and I don't have to worry about them getting sick.

I walked into my daughter's room and her closet is infested with gnats, the master bathroom, and main bathroom are the same way just not as bad! I have the apple cider mixture sitting in each room, but it seems like they are getting worse instead of better.

        Since I first read your post, I had a serious problem with gnats. I hung sticky strips, just as you did, (Dollar Tree, 3 for a dollar). They are catching gnats like crazy! I didn't even hang them over anything, just hung them. Thanks for the tip.

        I put rubbing alcohol in a spray bottle and spray the windows. The spray will kill the knats almost instantly. Using something like this can be an attaction to children so its best to store it where they can't get it. It looks like water in the spray bottle. Also this doesn't get to the root of the knat problem. My mom poured bleach down her drains when knats got in the house.

        I made the mistake of using hedge apples to try to get rid of spiders, and instead I got a house full of gnats. :-( I put small bowls of vinegar out, with enough veg oil on top to thinly cover it. I was amazed at how many of those pesky gnats I caught in them. Literally hundreds of them.

        Question: Gnats in the House

        I have fungus gnats (that do bite) and or biting midges, and they are wreaking havoc with biting me and my dog. My carpet was brand new 2 years ago and shampooed frequently and almost dry when finished. The gnats or other insects are also leaving larvae and gooey brown stuff and sticky runny stuff on my things. Everywhere.

        What do I do and how do I get rid of them in my house and stop them from biting us? They are all over the place. I am not a dirty person either. My dog gets a bath regularly and is on all preventions. Thanks.

        Our gnat infestation came courtesy of the 7 cords of firewood we brought into our basement for this winter's heating. Even though the wood had been "drying" outside for almost five months, it had been a wet summer. We used a combination of apple cider vinegar and dish detergent placed throughout the basement and upstairs rooms, fly paper strips, and up close and personal squishing!

        What seemed to work best was the fly strips hung in windows, with as many as six strips forming a curtain. (The gnats seem to favor light and would congregate during the day in sunlit windows; at night they'd flock to light bulbs.) Regarding Hot Shot Pest Strips (as with most chemicals): the instructions on the package are clear in their warnings about their danger to all living things and food; just because you can't smell it doesn't mean it's safe! Take the time to pursue pests with safe products.

          A female pregnant gnat can be trapped in the oven and lay her eggs there. Then, if you do not use the oven for a day or two, the new baby gnats will be released from the oven when you next open it.

          They are probably fungus gnats. They have to be breeding somewhere. If you can find the source (think damp/moist places) there is a product from Garden's Alive called No More Gnats, that I use on my houseplants when I start to see gnats.

          RE: Problem with Gnats

          I too deal with gnats and here is how I cut down on them. First, put away ALL food, including fruit in the fruit bowl. Put food scraps in bags before putting in trash can, and empty trash frequently. Make a gnat trap-a small bowl of vinegar with a few drops of dishwashing liquid works well-change frequently. You can also put a piece of banana in a jar, stretch plastic wrap over the mouth and secure with a rubber band, then poke holes in plastic wrap-they can get in but they can't get out. This get gross after a while. At night, pour some bleach down EACH drain in your house, and plug-that is where they breed. Good luck. :-)

          RE: Problem with Gnats

          The best solution I have found for gnats in the kitchen is as follows: take a large glass or jar, put a little cider vinegar in the bottom and put saran wrap over the top, secure with rubber band. Make a very small hole in the top just big enough for a gnat to get through. They will come in to get the vinegar, but cannot find their way out. This works very well for me.

          RE: Problem with Gnats

          Place a piece of banana peel into an old ketchup bottle (long necked small mouthed bottle) lay the bottle on it's side at night. In the morning the flies should be in the jar enjoying the banana peel. Without moving the jar place the cap on, locking the bugs inside. You can toss out the bottle trap or just wash it out outside and reuse again if needed.

          Place a few chunks of a ripe banana in a large jar that has a lid that will fit it. Lay it on its side and leave it be. I usually lay it on my sink overnight and in the morning very gently put the lid on, turn on the Hot Water, carefully remove the lid part way and let the water go in. It kills the gnats.

          The water must be very hot to work as the cold water only stuns them. It works every time. It might take several times but shortly your gnat problem will be under control. Warning: You must not leave the banana and jar unrinsed as the Gnats will lay eggs! Don't ask me how I know!

          RE: Getting Rid of Gnats

          To the person with who says they have little black gnats that are not attracted to the fruit remedies... I think those flies are called Sewer Flies. Cleaning all of the drains in the house with some enzyme eating chemicals is what I have seen work. Not an expert on this but at least you have the name of the black type of flies which is Sewer Flies. You can google that name on the internet and even see a picture to verify you have the right species and get suggestions for their removal. (03/30/2006)

          A bowl of vinegar with a spoon of dishwashing soap,than gnats are attracted by the vinegar bet the touch of dish soap breaks the surface tension of the water so the gnat try to feed but end up drowning, it takes several days but it works! (03/30/2006)

          I put 4-5 garlic cloves in one plant and change the cloves about once a month. It took me about 1 1/2 to 2 wks to totally get rid of the problem. Every now and than one will creep in but soon disappears!

          Hey... just to warn everybody... if you do the banana in the microwave trick... be careful because we learned that bananas are indeed flammable. The gnats definitely came into the microwave... but my Dad nuked them for 4 mintues and a few still flew out. We think they are now radiated super gnats.

          So, we are doing the vinegar and dishwashing liquid thing too and that definitely is working.

          Oh... and don't leave a banana peel in the trash can by your armchair... that causes gnat problem for sure (DAD!) (10/08/2006)
