Tarantulas--now that is impressive. My parents here in Florida had a strange ant problem for a few years. It was the same as you describe, they got into everything. They were apparently a South American species that unexpectedly arrived in their backyard and wiped out the fire ants that had been there for years. They tried everything to get rid of them, and then one day they all disappeared. Don't know what caused their demise, but the fire ants were back very quickly :)
