Thanks Kolt for the shout out. This appears to be a growing problem, I have had a couple of people send me private emails indicating this. Be sure to let us know how the outcome is. *One of the people used Barefoot's with Vermox and this was the only combination that stopped them - the poster did not do for a long period of time - I would also consider pulsing the substances, that is switching products around - but that should be done through observation.
