Will MotherEarth D kill waterbugs in my basement?

I have big, (up to 2 inches long) dark brown bugs in my basement. They look like giant roaches. These are also in my yard and on my porch. They come out alot more at night. Can I use boric acid or Diatomaceous Earth to kill them?


You did not indicate which product you were referring to but both diatomaceous earth and boric acid dust can be used to help get rid of the roaches indoors. Outdoors you should consider using a residual insecticide spray such as Cyper WP. Cyper WP is known to work very well for roach control and it offers a residual that can last for about 30 days outdoors and 90 days indoors. To help prevent roach infestations from moving indoors, apply to a band of soil and vegetation 6 to 10 feet wide around and adjacent to the house. Also, treat the building foundation to a height of 2 to 3 feet where pests are active and spray door frame, window frames, places where utilities (cables, pipes, wires) enter into the structure and other cracks and crevices.
