How do I get rid of the little flies that are invading my house plants?

I had some plants that I got from a friend who kept them outside during the summer. I brought them in when it started to get cold out, now ALL of my plants have these blasted little flies. I've tried using a bug spray to kill them off, but they keep coming back. I even replanted them in new dirt and put them in a different room, and they still came back. I don't know what else to do!

How do I get rid of the little flies that are invading my house plants?
Hi,

I have found that a systemic insecticide for houseplants works great.

I have also used a product that is in a liquid solution to be used as a soil drench that is 100% safe for everything, except fungus-gnats and mosquitoes. It's 100% organic because it is the natural occurring bacteria that the gnat and/or mosquito larvae feed on. This is the same bacteria that is used in "mosquito-dunks", which are used in outdoor bird baths and ornamental ponds, etc.

The site where I get mine is offered below.

I have had great success with this type of treatment for all my houseplants.

Professionals use this in greenhouses as a means of natural pest control.

You'll learn more at the site that sells the kind I use.

Hope this helps, Dave

I found the information at http://www.pests.in
Reply:Spray them with a very weak solution of Palmolive dish soap--that green stuff that's been around forever. Spray the whole plant down, and don't forget to get the underside of the leaves. You may have to do this a few times but it's harmless to the plant and to you. Good luck.
