HydroPy-300 ULD Pyrethrin will kill the roaches that it makes direct contact with while it is wet. It will not eliminate the roaches that do not make direct contact with the wet spray. To get control of the roach infestation you need to use an Insect Growth Regulator such as Gentrol IGR. American Roaches come from the outside of the home (usually attracted to lights), so it is best to spray a liquid insecticide around the outside foundation of the home such as Talstar One or Cynoff WP, rather than using roach baits. Also focus on sealing up cracks around doors and in the foundation so roaches can't get in.Also HydroPy-300 ULD Pyrethrin is currently off the market, as an alternative, we recommend a similar product called Riptide Pyrethrin ULV.
