We were having difficulty with gnats in our kitchen and decided to purchase the closed-top trash container (N fitted trash bags). This summer, we have "almost" no gnats. But what we love are the fitted liners (N) that are made for the trash container we bought. Because of their slender design, we can fill them to the brim and still get two of them, along with trash from our two bathrooms in one of the two large trash cans outside. We only have to go to the dumpster once a month now.
