How do I get rid of the gnats that are infesting the soil my house plants are potted in?

Question

I have a terrible problem with gnats in the soil of my house plants. I would like to get rid of them without chemicals. Can anyone help?

Answer 1

A 1/4 inch layer of sand on top of the soil will prevent future larve from crawling up from the soil. The adult gnats are short lived, so eliminating the next generation should solve your problem.

These gnats are also associated with spider mites. Leaves will exhibit pin point spots, if you look closely you'll see fine webs and very small (size of the dot over this "i") mites. To kill them use Disyston. Sprinkle on, water in.

good luck

Answer 2

I understand it is a chemical but 2 teaspoons of bleach per each cup of water should solve the problem without harming the plants. Be sure to mix it in the water not straight on the soil.

Answer 3

Yes, just mix a little bit of Dawn or other mild detergent with some water and spray them every couple of days. Make sure you get the leaves and under the leaves too. That should work.

Answer 4

you can try mixing mild dish liquid with water and spraying the plant with it. just a small amount will/should work. do not put so much on that it will foam up. i hope this works for you
