How can I get rid of fleas that came from a cat in an apartment? - briefly

Repeat cleaning and treatment after one week to break the life cycle.
How can I get rid of fleas that came from a cat in an apartment? - in detail
Treat the animal first. Use a veterinarian‑approved flea shampoo or a topical product (e.g., fipronil, imidacloprid) applied according to the label. Repeat the treatment after the life cycle completes, typically in two‑week intervals, to kill emerging adults.
Sanitize the living space. Wash all bedding, blankets, and removable fabric covers in hot water (minimum 60 °C) and dry on high heat. Steam‑clean carpets, upholstery, and curtains; the heat kills eggs, larvae, and pupae. Vacuum floors, edges of furniture, and cracks in walls daily for at least three weeks, discarding the bag or emptying the canister outside immediately.
Apply an environmental insecticide. Choose a product labeled for indoor use against fleas, such as a pyrethrin spray or a diatomaceous‑earth powder. Follow the manufacturer’s directions, covering baseboards, under furniture, and crevices where fleas hide. Re‑treat after seven days to address any survivors.
Set up flea traps to monitor progress. Fill shallow dishes with warm water, add a few drops of dish soap, and place a light source above each dish. Fleas attracted to the light will jump into the water and drown. Replace traps every 24 hours and record catches.
Prevent re‑infestation. Keep the cat on a regular flea preventive regimen (monthly oral or topical medication). Restrict the pet’s access to untreated outdoor areas. Maintain a routine of frequent vacuuming and laundering of pet linens.
If infestation persists after four weeks of combined animal and environmental treatment, consult a pest‑control professional for a targeted fogging or residual spray program.
