1. An aqueous formulation comprising:
- nanoparticles comprising a polymer and a pyrethroid compound with an average diameter of between about 1 nm and about 500 nm;
wherein the polymer is a polyelectrolyte copolymer comprised of between about 50 weight percent and about 95 weight percent methacrylic acid monomers and between about 50 weight percent and about 5 weight percent ethyl acrylate or styrene monomers;
between about 0.5 weight percent and about 5 weight percent of a naphthalene sulfonate condensate dispersant;
between about 0.5 weight percent and about 5 weight percent of a sodium dodecylbenzene sulfonate wetting agent;
between about 0.1 weight percent and about 1 weight percent of an anti-foaming agent;
between about 0.01 weight percent and about 0.1 weight percent of a preservative; and
water;
wherein the nanoparticles comprise between about 5 weight percent and about 50 weight percent of the formulation.
