ok, but the solution is necessarily structural. there aren't any good pesticides, and we can't grow the amount of food we need without them.
i suppose stricter regulations might help act as an incentive to build more indoor growing sites. but, i'd rather be pro-active. and in fairness this government actually has been pro-active about encouraging indoor growing.
