Our kitchen has large windows that are oriented to the south. This we have temperatures of over 25 ° C even in winter when the sun shines. This high temperature made sure that we have stored in our past only fruit in the refrigerator, because the basket on the kitchen table immediately emerged fruit flies. Since we did not forget from time to time to put away the basket after dinner, we had a short time later a fruit fly plague that was uncontrollable. Eventually I bought the product at Amazon and was surprised at how well it works. The supplied Beschälter containing fruit vinegar, was full after 2 hours with the fruit flies. Our fruit basket, we can stand on the table since the container and must accordingly more often buy more fresh fruit.
