Hello, anyone have any suggestions on how to stop them from sucking on each other??? I am spraying there back ends with vinegar but it’s not stopping the issue. If I could separate them I would but that’s not an option. I read that some add Tabasco to the vinegar, but I would need to know exactly how much? I’ve also read something about Vick’s?? Anyhow, I appreciate any advice because this is a HUGE problem!!!
