Flea control that breaks the whole life cycle

Because the adult fleas on the pet are roughly five percent of the population. The other ninety-five sit in carpets, bedding, under furniture and in shaded yard spots as eggs, larvae and pupae. Pet treatment stops the next generation of eggs; home treatment takes the stages already on the floor. You need both at once.

Wildlife. Opossums, feral cats and rats bedding under decks, in crawl spaces or in the attic shed flea eggs that hatch into the house, and when the animal moves on, the fleas come looking for the next host, which is you. Finding and closing that bedding site is part of the job.

Expect bites to taper over about two weeks. Pupae in cocoons resist every treatment until they hatch, so a short wave of new adults after treatment is normal and they die on contact with treated surfaces. A follow-up visit is scheduled inside that window.

Vacuum every floor thoroughly right before the visit, including under furniture and along baseboards, and wash pet bedding hot. The vibration and the cleared surfaces both help: vacuuming triggers pupae to hatch into treatment and lifts eggs out of the carpet.

Not entirely. Murine typhus, a flea-borne illness, is now concentrated in eastern Los Angeles and Orange counties, carried by fleas on rats, opossums and feral cats. Most flea problems are pet-driven and simply miserable, but a wildlife-linked infestation is worth treating promptly for more than comfort.
