Does anyone know the best way to get rid of gnats?

Question

I don't know where they are coming from, but we have gnats in our office and they totally gross me out. They make my skin crawl. I'd like to know why they appear and how to get rid of them.

Answer 1

You might have fungus gnats, which live and breed in the continually moist soil of the decorative potted plants and greenery in your office.
Trapping the adults can be difficult, but there are several ways to kill the larvae to prevent future generations.
If you are "green" and organic, some people recommend covering the soil in the pots with about an inch or two of sand, the theory being the sand is too difficult for the newly emerged adults to crawl up and out of.
If you are not organic and okay with a mild pesticide, a simple spray containing pyrethrin on a regular, once a week application (spray two squirts on the moist soil of each pot in the office, first every other day for two weeks then once a week thereafter - it's plant-based so it won't kill the plants.) will help reduce the gnat population.
The other thing to do is to convince whoever has the plants to not water them every day. Most houseplants are killed by too much water. Cut the watering down to once a week and let the pots dry out a bit. Fungus gnats breed in moist soil where fungus grows ( the larvae feed off of the fungus and roots in the wet soil), and dry soil is not their home. By drying the soil out a little, you can reduce the gnats.
Good luck. The gnats don't bite but they can be a real nuisance.

i know bc i tried this in my house... get like a jar and put a little bit or wine or red gatorade in the botten or even some cut tomato or watermelon and let the jar sit without a lid for several house many of the gnats will drown in the liquid and if u use fruit wait untill its almost full of gnat then quick screw the lid on and u can use bleach on any leftover gnats they don't like the smell i guess and i found where ever i sprayed a bleach and water combo they don't land there for a few more hours and in that time planty of them will leave...

Answer 4

leaving out a small bowl (1/2 cup) of red wine in the open near the gnat concentration for about 2 weeks will get rid of them. make sure you refridgerate any fruit and don't let the dishes pile up.

I hate those things.. good luck!

put a capful of downy liquid fabric softener in a baggie then pierce several holes above the level of the downy to allow the scent to escape the baggie then hang the baggie near the source where the gnats are ...they will flee , this works for love bugs and other insects as well

Answer 6

Since you mention they are in your office, check the office plants. That may be a source for the gnats. If so and your plants are cared for by a plant service, call them to take care of them. Could be they will have to switch some plants out for some fresh ones. We had that happen at our office.

Answer 7

This actually works, get a cup,cut and orange in half, cover the hole with plastic wrap, and poke holes in it with a toothpick. The gnats fly in attracted to the orange, but can't get out.

Answer 8

I use a bowl with about 1/2" of cider vinegar and a couple drops of unscented dishsoap in it. You will soon see many drowned gnats.
