I see One Huge problem with 1/2 of these suggestions. 1 person already said it JUST BECAUSE YOU DON'T SEE GNATS DOES NOT MEAN YOU FIXED THE PROBLEM!!!! They feed on the roots of your plants the actual gnats do nothing so all you are doing by adding the Venus fly trap is making food for it lol. they harm your roots you need to get rid of the larva in your soil i find drying out your soil some what helps but gnatrol is probably a good idea. I need to order me some i think because they are starting to come back since i got rid of them a month ago...(by drying out the soil.) oh well good luck by the way when you transplant you can literally see the little white buggers stuck to your roots so get rid of them.
