    Vinegar Kills Plants. It Kills Almost all Plants. I Use a mixture of Vinegar & Dish Soap & Water to Spray & Kill Weeds in Flower Beds & Other unwanted plants. It Doesn't Kill some plants completely some after the foliage dies will return from the root but others completely die. This is not safe to spay on Your houseplants or around or any plants You don't want to Kill. Look it Up. I have been Using Vinegar & Water to Kill Weeds forever. Also If You have a Fish Aquarium check Your water pump filtration they can make their maggot-filled nest in them.

    Before you spray, remove every crumb of food. If they're in the kitchen (mine were), take out or freeze your trash and compost, and leave the pail outside. Check for open containers and hidden sources of food. I think mine were feeding on the crumbs inside the toaster, so I had to thoroughly clean it. Clean all the dishes and put them away and clean all the surfaces, including the cupboard doors. If you use any dishes, wash and dry them immediately and put them away.

    The spray (1 cup water, 1 oz vinegar, a few drops of dish soap) misses most of them. I presume some are missed because they're so small that most pass between the droplets of spray without being hit. But it kills some of them, and renders some more unable to fly for a few minutes. If they fall where you can wipe them up, you kill the flightless ones as well. The survivors will scatter and disappear for a while. After 30-60 minutes, they're back. Spray them again and again several times per day until finally you get the last of them. Mathematically, if you kill 30% of them each time, you'll be down to 6% in 8 sprays. If you started with 50, you'd be down to three. When the population down to one or two, kill those ones and you're done. It took me about a day and a half, spraying every hour or so.

    I think you mean "perish". A parish is a local church community, a diocese committed to one pastor.

    I have had an issue with some mysterious flying insect species in my one bedroom and loft apartment for three months. The first month I was bitten multiple times. The insect is invisible, if it likes to attack me wherever I am, in the home. I feel a prick or something hovering near my head or skin. My manager keeps saying the pest control people need to know what is the insect first. We have concluded or speculated today that it might be gnats, from an example bug in the next building. You mention spraying the gnats but they are not visible to the naked eye. The only water flow is in the kitchen and bathroom. Should I frequently spray the sink area and under the sink and inside the dishwasher, and spray the bathtub? Should I also spritz the open areas?

    I'm confused. It says you need a spray bottle, dish soap, water and/or baking soda and vinegar. It doesn't say how much or what to do with it. Did I miss something? I'm blonde, so it's completely possible...

    It's not clear what you mean, "dish soap, water and/or baking soda and vinegar." Baking soda and vinegar in solution react and foam up. That might be okay for pouring down a drain to clean it, but it's not going to work in a spray bottle. Do you really mean mix them together, or do you mean "dish soap, water and baking soda; or dish soap, water and vinegar"?

    Just make a solution from water mixed with a few drops of dish liquid. You can use this to spray on the flying gnats or spray inside your trash can with or without the trash in it. It works for plants and fruits and veggies. Also in summer downsize your trash can so trash is taken out more often. I leave about two inches of soapy water in my sink overnight and leave a banana peel in it, make sure the peel is just covered by water and soap bubbles. Gnats die once landing on the soapy bubbles and water.

    That's the problem she does'nt go through all the steps just gives what you need and drops it. I've done the vinegar and water and dish soap for at least a week now and it kills millions of htem but after a few days it's HUGE again and it just keeps killing them but never gets rid of them, what else do you got. We have no standing water in our bathroom other than the toilet. I do'nt see them coming out the drain and I cleaned the drain and it's clean. (under the sink) I need more help. We don't have standing water and no food.. the trash is emptied every day all over the house... Grrrrr

    We have a small terraced area outside our back door, where we like to have breakfast and morning coffee. We have, what look like small fungus gnats which hover constantly.

    We tried Dishsoap and vinegar method and it worked. We saw them dying instantly. I have also read that borax can be quite helpful too in fighting these pesky pests. [Source]
