Yeah, to me this just looks like a case of false positive pattern recognition, given the relatively tiny number of conspiracy-theory-style complaints about it.

All you need is some more or less benign targeted advertising by local exterminators (for example, "age 22+", "females and married couples", "single-family dwelling", and a zip code the exterminator knows have had lots of bug complaints) and somebody happening to glance at their phone after being spooked by bugs.

(You may be creeped out by Facebook knowing what type of dwelling you live in, but that's a separate issue.)
