Black Flag bug spray tv commercial

We're spraying one half of this digital calendar with a leading roach killer and the other half with the long lasting killing power of black flag ant and and roach spray. Now we wait 5 10 15 days then pour on live roaches. Look, the other leading spray has no residual action. Roaches are still alive while that one spray of Black Flag with Beon 15 days ago is still deadly. Black Flag, one spraying kills roaches for 15 days.
