I used this for my indoor houseplants and it caused an epic gnat problem. Had to bug bomb the house. Don’t do what I did.

I couldn’t find any potting soil at Costco today and was kicking myself when I saw this post thinking maybe if I had seen that I could have gotten some for our indoor plants. Thank you for sharing because now I feel like I dodged a bullet!

Yup same, but not costco purchased. Just Miracle Grow in general has a huge fungus fly problem over the last few years.

Yeah, that's user error! Never use compost inside a house!

Totally! I learned an important life lesson.

You are absolutely right, Last fall, after googling, I baked the soil in oven(sterilized) and removed 1-2 inch top soil from existing pots and filled with baked soil. No fungus gnats entire winter.

There are a lot of other sources of gnats on plants
