I've tried using Vaseline as a barrier for my ants, but some of my species walked over it, and put substrate on it, making a huge mess. I'm thinking about using olive oil instead, but it too has its pros and cons based on other people's experiences. I currently don't have any rubbing alcohol, talcum powder/baby powder, or Fluon. Pretty much in a bad situation as I have a few colonies that need it soon. If anyone knows any other barriers I could use, that would be greatly appreciated.


I plan on using olive oil though, if I have no other option. Thanks again for any suggestions or advice.

It either works well or doesn't work at all. Depends on the type of ant. I know my Camponotus can climb up it no problem but most of my other ants cannot.
