has anyone found a successful means of controlling carpenter ants? There's lots of conflicting opinion out there about whether or not bait is effective. And many different dusts. There's also not much info on Eco Exempt, a somewhat new method being used.
Thanks- gale

EcoPco WP-X is a good source for treatment for carpenter ants. Must be mixed very well but it works. Advanced Carpenter ant bait works good also but not organic but will control the problem in 21 days and has a small impact since it is a grainular.
