Raid Perimeter Protect Bug Barrier, 30 oz Bottle

I apologize for the confusion in the product description. After reviewing the information provided, I can confirm that Raid Perimeter Protect Bug Barrier is designed to keep German cockroaches out and kill them for up to 18 months on non-porous surfaces. This means that the first point in the description is accurate. The product also provides residual control and can continue killing German cockroaches for up to 12 months on non-porous surfaces, which means that the second point is also correct. In summary, Raid Perimeter Protect Bug Barrier keeps German cockroaches out and kills them for up to 18 months on non-porous surfaces, while also providing residual control and continuing to kill them for up to 12 months.
