How to get rid of unknown pests?


I have about 15 planters in my indoor garden. Recently I have started seeing these little fruit flies looking buggers flying around them. I am not over watering my plants and they are well drained. I do not know where these buggers are coming from or how to stop them. Does anyone have any suggestions?

Sounds like it might be fungus gnats. You by any chance haven't used the Miracle Grow African Violet soil have you? It's stuffed full of fungus gnat larvae even though they swear it's clean when it leaves the factory.

If your plants are African Violets then you will need to replace the soil. Mix up some regular peat based soil with perlite and replant. First you'll have to wash off all the soil from the roots and don't be worried about getting the crown wet. Once you've got all the soil off, take a folded paper towel and insert it between the stems of the plant to get all the excess water off of the crown and repot. I did that to all of my AV when I had fungus gnats and didn't lose a one.

Do the same for any other plants .. insecticides and stuff just doesn't work .. you have to replace the soil.

I am using miracle grow potting soil. I don't have any African violets. I have 3 different shades of Christmas cactus, 3 types of desert rose, a wandering Jew, a spider plant, a goldfish plant, a sensitive plant seedling, and seedlings of coleus and Bolivian pepper plant. I am worried that these flies are eating my seedlings.

I'd try a different soil. Here is a good fact sheet about them:

Fungus Gnats

It was probably diatomaceous earth.

I use dish soap and water, I just put in dish soap with my water and mist my plants with it, that's the only water i use now, and it helps lessen the population

I had a fungus gnat infestation this summer. I sprinkled cinnamon on the top of the soil and mixed it in about an inch or two down in the top soil, then watered all of my pants a few times with a peroxide/water mixture. I not only killed the adults but got rid of the larva. If you don't treat the soil the gnat larva will hatch the next time you water the plant. They can lay dormant for quite a long time.

Pink and Barefootsucclents have offered some very good advice.


Also too, remove the top two inches of soil, in the gnat infested pots where gnats and their eggs reside, and replace with fresh clean soil. This will help to instantly rid the problem.


Miracle grow soil, or as a good friend of mine on the site calls it, "miracle death"....is one of the worst bacteria & bug-ridden soils on the shelves! Avoid it altogether and get yourself some clean sterile soil. Sunshine professional mix is an excellent alternative and it can be found at most nurseries for not very much money at all.


A spray bottle filled with dish soapy water is an excellent weapon against flying gnats too.
One spray and they'll be goners.


Good luck.
