I've been having no luck for the past 3 months with containing my ants in their outworlds by using fluon on a vertical surface, so I think I'm going to need an upside-down lip surface to apply it to, like this:

It seems that containers with upside-down lips to apply your deterent on are very scarce - AntsCanada has them (picture above) but I don't want to pay 100 dollars for each outworld. AntStore has super nice looking add-on lips and outworlds, but they won't ship outside of Europe (sometimes even out of Germany), damn that. ![]()
I'm having so much trouble with feeding my ants lately as my colonies are growing in their tubes. I get escapees almost every time I open their tubes to feed them and it's a real problem. They are walking over fluon vertically like it's nothing (no matter how I apply it or what kind of surface I apply it to, glass or plastic) and it's getting to be a real setback, especially as of the last day ever since I came back from vacation and my colonies are 5 times bigger and getting nearly impossible to feed without their outworlds.
I feel like the other barriers (Olive oil, vaseline, talcum powder, etc.) will do just as bad since fluon is considered the top barrier, but I'll try them out if I get the chance. I might have some of that stuff lying around the house.
So does anyone know of or suggest any containers/outworlds with an inside lip excluding the ones from AntsCanada and Antstore? Or any other suggestions/help with my barrier troubles? Thanks!
