Sorry I took so long, trouble with internet access. Seems MP3 Rocket bans us from the internet. Anyway, all I do is use my finger to smear a film around the base outside and inside. Doesn't take much and lasts real well. Bees ignore it since it's out of their normal traffic. I have SBB so thats why I smear the inside if the base. The film is only as wide as my finger and the ants refuse to pass it.
