Hi guys (Anti-Escaping System question)

Hi guys, i've registered here because i found about the site via Entomodena im hoping of cooperation with you guys preferably in English, if necessary in Italian and i will translate it somehow,but i've found out that i can understand quite a few words. I live in Serbia, Novi Sad and i drive an Alfa Romeo 147
also i own tarantulas, L.parahybana,G.pulchripes and B.klaasi, ofcourse i have ants, they're in 3 separate test tubes, i have 2 queens of C.vagus and 1 queen M.structor. I've been keeping ants for around 3 years but very unsuccsessfully. My queens died and i've had problems with containing them in the basin area without them escaping,but i've recently found out about a mix that could keep them from escaping, baby powder+alcohol (70%) is this a good method?
Cheers, David
