The advertisement features a representative of the creature or item the product is supposed to wipe out. The Talking Pest will start by bragging about how well things are going for it. Then the product is used. Sometimes the pest is evicted, and bitterly complains as it is leaving. Sometimes it is killed, and viewers get to hear its last scream. Sometimes the Talking Pest is cute. On occasion, it is the basis of merchandising.
The logic behind it is to convince viewers that the various insects and maladies out there are making them miserable not as a by-product of them doing what they naturally do, but rather because they just love to piss people off. See, it brings them joy to munch on your wall studs and give you athlete's foot, so you have buy the advertised product and give 'em their due punishment!* Of course, this can result in Fridge Logic when you realize that showing the graphic death of an insect is more disturbing when the insect is anthropomorphized so much that it has apparent human intellect and speaking ability.
