Hey all, I posted this in r/dogadvice, but want to get parental advice as well, since we have an infant. We've never even dealt with this before as childless pet parents, and it feels all the more daunting with a baby. 😭 Thanks!

Last night I noticed a little black dot on top of my dogs fur. We live in New England so I always assume its a tick. I picked it off, pinched it, and investigated. It did not die (typical), but it JUMPED. TICKS DON'T DO THAT. 😳 I was able to find it, squash it, and confirm it's a cat flea. I immediately flea combed her and nothing came up. I flea combed my other dog and nothing came up, but we did find one more flea on the blanket she was on. We tore apart the couch, the blankets, everything in the vicinity and did not find any others. I flea combed the dog bed fluff and picked every last crumb out of the creases (🤢), and I did not find another flea or flea dirt (anything that crumbled was grayish, not reddish).
We also have an indoor/outdoor cat that lives in the basement at night. Since its summer, he is out dusk to dawn, and we barely see him. He does, however, walk across the back of the couch to get from back door to basement door without dealing with his psycho sister (husky pup 🙄), and the first flea was on the couch and the second next to it. We figured he was the culprit, but I flea combed him and investigated all the little nests he has the basement and again, nothing. No fleas or flea dirt.
All 3 have seresto collars on, so I'm a little shocked that this is even an issue. In 12 years of pet ownership (as an adult, an additional 18 years growing up with cats and dogs), we have never once had fleas. Is it possible that they carried them in on their fur from outside, and they hadn't had a chance yet to burrow in and bite them (and presumably die bc of the serestos)?
My partner also floated the idea that she might have picked them up on the airplane (she got home Sunday night and we found them Monday night). Not sure if this is even possible, but we are just so baffled by this.
To make matters worse, we have a 4 month old and are doing some major house changes. We are rearranging so he has a room of his own. He came early so the project was interrupted and has been hella slow progressing bc, well, newborns. There are bags of fabric and yarn that are piled up in the dining area and on the stairs awaiting their new home. So this is literally a nightmare scenario for us right now.
We plan to get in contact with the vet and pediatrician in the morning for proactive advice, maybe a mobile groomer to avoid putting the dogs in the car (RIP in peace to our bank accts😭).
tl:dr: 2 fleas found, one on surface of fur, one on a blanket. All 3 animals flea combed (nothing found). Living room torn apart (nothing found). Pet beds/fave areas investigated (nothing found). 3 newish Serestos (June) on all 3 pets. Added complications: infant and moving clutter primarily made up of fiber materials (the clutter, that is; the infant is human). Plan so far: call vet and pediatrician in the morning to get advice. Do we freak out yet? What else should we do to nip this in the bud?
