Boecker - no doubt what? (update)

 

Boecker, like Entotox - Truly Nolen - and Kimbo before it, is now doing pest control ads. Where Entotox opted for something slick, Truly Nolen went slang, and Kimbo was funny, Boecker goes for something cryptic a la Beckett which you can interpret in millions of ways, and none of them makes a lot of sense. "No doubt!" goes the slogan.
Please interpret as you wish, personally I was too confused.
Small update: I was made aware of this ad which is on Instagram, which explains the "no doubt" mystery. But does not justify posting such an ambiguous ad on the streets!
