I'd be more than happy to trade with ants if they were willing to. They could clean floors and furniture, get rid of plant parasites, check the status of wiring and plumbing. I'd pay them in sugar, that would be a great deal for both parties.
They do the first two (clean and eat bugs) and will happily take sugar in the form of bread an cake crumbs you leave out on surfaces. We're already quite symbiotic
