Re: Cockroaches in Vivarium - Is this plan OK?
I've used this method successfully for years. Put some roach gel into the small container (I bought these at a dollar store.). Place the container into the vivarium at lights out, but don't do it on a feeding day as you don't want the flies to eat the gel and then get eaten by a frog. The roach will enter the container, eat the gel, leave the container and then die. You can remove both the container and the dead roach in the morning.
