- Tuesday, February 26, 2013 knock out gnats Reviewed By: Rebecca (Los Angeles , California) This product is very useful to me, please continue to allow it to ship out to the state of California. I have a severe problem with gnats and the larva need to be controlled. I still have some of it and I noticed a major decrease in the gnats after I used this product within two days. I want to order more in the future to send here to California. Thank you. - Sunday, June 23, 2013 Love this product Reviewed By: mark (leaving blank, pennsylvania) I work in a sealed office building (cannot open the windows). Over the years people brought in gnats with their plants. Since the office is sealed, natural predators cannot get at the gnats.
I found this product here when desperate for something to knock down the gnats. I had been warned I would have to remove my plants otherwise. It worked quickly. Periodically I would refresh it with a simple watering of this product. I used it on the plants of some coworkers when they let me. I ask management to authorize me to use it on the other plants in the office. Still waiting for that. But at least management knows this product exists.
Without question it kills the baby gnats breeding in the soil of the plants. Here back for more of it.
