Dealt with fungus gnats for literal years and frankly just didn't care enough to do anything about it. Recently got a bonsai tree as a gift and knew that I had to make a real effort to cure my plants so they wouldn't spread fungus gnats to such a delicate plant. I treated them with this product for the first time about 2 weeks ago. Whenever I saw even 1 gnat in my apartment, I went back and treated them again. So I believe I've treated them 3 or 4 times. I haven't seen a gnat in several days now. Hopefully they are gone for good! And I still have 3/4 of the bottle left if I need to follow up

Unless you only have one plant buy the concentrate. One tablespoon of concentrate makes a gallon.

I've tried other methods to get rid of these annoying fungus gnats; this product works! The number of the gnats decreased immediately and then were completely gone in about 7 days. The plants remain healthy. I combined this with glue traps to catch the ones trying to escape.

My tomato plants started being attacked by Hornworms and this was recommended by a tomato growing guide. I use this about once every 2 weeks and so far haven't seen any new hornworms, or seen any new damage caused by them. Smells awful, but really does work. Plants look very happy now.

I bought this product on the recommendation of the Youtube channel Garden Answer and it works great! I have a patio full of potted petunias in the summer months and I spray at the first sign of tattered blooms or reduced flowers. I try to apply it 2-3 days in a row and then all signs of budworms disappear for weeks. It smells sour but I don't notice the scent lingering after application. The only way this product could improve is if the packaging incorporated some kind of continuous spray.
