Expectant roaches carry their eggs in a largish brown sac called an ootheca, a firm-walled egg case attached to Mama Roach's posterior. A roach ootheca is about the size of dried bean, not something that could be worked into anyone's gum line.

Consider this. A pregnant roach carries her eggs in a hard capsule called an ootheca, in which they incubate intact until the larvae (or "nymphs") hatch, bursting the capsule open. The eggs themselves can't survive at all outside the ootheca, let alone flourish within the body of a mammalian host. You're not likely to find individual cockroach eggs strewn about on random surfaces, in other words — certainly not across the flap of an envelope.
