Janet certainly seems to imply in their fight that both the pheromonal communication technology and the heightbased powers are derived from her. But that's IMPLICIT merely because of the way she says, "Let's see how many powers you can make that don't involve shrinking and growing and talking to insects through a helmet, you jackass!" (I'm paraphrasing.)
I think an interesting way to explain the pheromonal technology but her apparent lack of "insect talking" powers is to hypothesize that maybe Janet's body is also designed with pheromonal communication, but only so she can communicate with her potential young.
Meaning her body has the ability to talk to mutant bug-men and women that she would eventually give birth to. So even though she doesn't talk to insects, its possible that Hank took that aspect of her biochemistry and reengineered it to work on plain bugs.
