  Abstract  
  Control of insects by the consumer, within the home and around the perimeter to prevent pest invasion requires products that have certain key features. These include fast action, extended activity, low/no odor, no marking/staining of surfaces, and convenience of application. Current products that are used to control cockroaches, ants, fleas and other pests include aerosols and water-based emulsions. A new water-based formulation of deltamethrin (DeltaGard®) has been developed that captures the features described above in a ready-to-use form. One of the useful properties of deltamethrin among the pyrethroids is its crystalline nature, even at elevated temperatures, making it possible to produce water-based suspensions. Once applied, these formulations are highly effective and long-lasting, even on absorbent surfaces. The new formulation will provide the homeowner with an extremely user-friendly approach to insect control, both in and outdoors. Visibility of the deposit and odor are negligible and there is no requirement to shake the formulation prior to use. Biological performance is exceptional for a homeowner product. Fast action and extended efficacy on a variety of surfaces is demonstrated against a wide range of public health and nuisance pests.
