I had a very similar issue a few years ago with Miricle grow. I was repotting all of my house plants, as I do each year with Miricle Grow potting soil. A few days later I thought i had fruit flies. So I put out traps and none were going for it...more research...they were fungal gnats...apparently a known problem with Miricle Grow...more research...removed all soil, washed off roots of what I could save and use black gold soil...no more gnats...if you are interested research it...you'll be angry.
Used to love them, now I will never use any of their product again.
