Fleas are a lifecycle problem, and that is why they are so hard to shake. Most homeowners see fleas on the dog, treat the dog, and expect the problem to be over. A few weeks later the fleas are back. What happened is that the eggs laid before treatment hatched, the larvae matured in the carpet and the yard, and the new adults jumped back onto the pet the first chance they got. Breaking that cycle requires attacking all four life stages: egg, larva, pupa, and adult, across every environment the pet uses.
Quick answer
You have to treat the pet, the home interior, and the yard at the same time. Treating only the pet leaves hundreds of eggs and larvae in the carpet and yard. Adult fleas are only about five percent of a flea population. The rest are eggs, larvae, and pupae hiding in your floors and outdoor areas.

The Life Cycle You Are Actually Fighting
An adult female flea lays eggs on the host animal, but the eggs do not stay there. They fall off into carpet fibers, pet bedding, floor cracks, and outdoor soil within hours. The eggs hatch into larvae that feed on organic debris in the environment: flea dirt (digested blood), dead skin, and other organic material in the carpet or soil.
Larvae spin a pupal cocoon that is sticky and picks up environmental debris, camouflaging it in carpet fibers and yard debris. The pupal stage is the most resistant of all. The cocoon protects developing fleas from pesticides, and pupae can remain dormant for weeks or months, emerging when they detect heat, vibration, or CO2 that signals a host is nearby. This is why a home can seem flea-free for weeks and then explode with adult fleas when occupants return after a vacation.
Treating Your Pet: The First Step, Not the Only Step
Your veterinarian is the right resource for the pet itself. Monthly topical or oral prescription preventatives are significantly more effective than over-the-counter flea collars or shampoos. A bath kills the fleas present at the moment but provides no residual protection.
Start the pet on an effective preventative before or at the same time as the home and yard treatment. If you treat the environment and not the pet, fleas on the animal will reintroduce them to the clean environment immediately.
The Interior: Prep, Vacuum, and Treat
Before any interior treatment, vacuum thoroughly: every room the pet uses, under furniture, along baseboards, and inside couch cushions. Vacuuming removes a significant percentage of eggs and larvae and, importantly, stimulates dormant pupae to emerge before treatment is applied. Empty the vacuum canister outside immediately.
Wash all pet bedding on the hottest setting possible. Move furniture so treatment can reach floor edges and corners. A professional interior treatment uses products that combine an adulticide with an insect growth regulator (IGR), which prevents larvae and pupae from developing into reproducing adults. The IGR component is what breaks the cycle long-term.
The Yard: Where Re-Infestation Comes From
The shaded, moist areas of your yard where the dog sleeps, plays, or spends most of its time are the highest-priority outdoor treatment zones. Fleas avoid hot, dry, sunny areas. They need humidity and shade. Under the porch, along fence lines, under shrubs and deck structures are the spots that harbor larvae and eggs outdoors.
A yard treatment should cover those harborage areas along with the pet's typical path through the yard. Rake up and remove leaf litter before treatment so the product reaches the soil surface. In Houston's warm climate, outdoor flea populations can persist year-round, which is why treating just the interior often does not hold.
