Even though that picture is over three years old, as for your questions, you shouldn't have to make the food land on the web. In a container that small, the sling will still get the insect. You shouldn't have to do much maintenance on the web, but even so, removing the top and flipping it upside will work fine. And with the container flipped upside down, just a little prodding will get it to run 'up' and out of the container. Easy to retrieve the sling.
