Boric acid will not work for bedbugs because it has to be ingested to kill the insect. Bedbugs have sucking, piercing mouth-parts which do not allow them to ingest the powder. Other dust insecticides such as Alpine Dust or Tempo Dust work from the outside and will kill bedbugs. Please see our bedbug kits to see the products we recommend to be used to get rid of bedbugs.
