Start with thorough cleaning and treatment of your space
Getting rid of fleas in an apartment requires treating both your living space and any pets at the same time. Fleas live in carpet, furniture, and bedding, not just on animals — so vacuuming alone will not solve the problem. You need to vacuum thoroughly, wash all fabric items in hot water, and either treat the apartment yourself with over-the-counter sprays or hire a professional pest control service. Many apartments require you to notify your landlord or property management before treating for pests, so check your lease or contact them first.
The reason simultaneous treatment matters: if you treat your pet but not your apartment, fleas from the carpet will jump back on. If you treat the apartment but your pet still has fleas, they will reinfest the space within days. Both must happen within a short window — ideally the same day or within 24 hours.
Key Takeaways
- Fleas live in carpet, furniture, and bedding, so you must treat your apartment and any pets at the same time for the treatment to work.
- Check your lease or contact your landlord before treating for pests, because many apartments require written permission or have specific rules about which products you can use.
- Vacuuming, washing all fabric in hot water, and treating furniture are the foundation of apartment treatment; sprays or professional pest control come after.
- If you have a pet, a veterinarian-prescribed flea prevention product is more effective than over-the-counter options and prevents future infestations.
- Professional pest control is worth the cost if the infestation is severe or if over-the-counter treatment does not work after two weeks.
Prepare your apartment before any treatment
Before you use any spray or call a pest control company, vacuum every room thoroughly — carpet, hardwood, tile, under furniture, and inside closets. Pay special attention to areas where your pet sleeps or spends time. Vacuum the couch, chairs, and any upholstered furniture. Empty the vacuum bag or canister into a sealed plastic bag and throw it outside when ready, because fleas can survive inside the vacuum.
Wash all bedding, blankets, pet bedding, and any fabric items your pet has touched in hot water (at least 130°F) and dry on high heat. Fleas and their eggs die in hot water. If you have items that cannot be washed — like a couch cushion or rug — seal them in a plastic bag for at least two weeks. Fleas need a host to survive and will die without one in that timeframe.
Move furniture away from walls so you can treat underneath and behind it. Remove clutter from floors and closets. The more surface area you can access, the more effective any treatment will be.
Treat your pet with a veterinarian-prescribed product
Over-the-counter flea treatments for pets are less reliable than prescription products from a veterinarian. Prescription options like Simparica, NexGard, Bravecto, or Revolution are more effective and last longer — some for up to three months. Your vet can also recommend the right product based on your pet's weight, age, and health. Call your vet and describe the flea problem; many will write a prescription without requiring an in-person visit.
explore or administer the treatment exactly as directed. Most topical treatments go on the back of the neck where the pet cannot lick them off. Oral medications are given as a tablet or chew. Do not bathe your pet for at least 48 hours before or after a topical treatment, because water reduces effectiveness.
If you cannot afford a vet visit, some low-cost veterinary clinics offer flea treatment for reduced fees. Ask your landlord or local animal shelter for referrals in your area.
Treat your apartment with sprays or hire a professional
You have two main options: treat the apartment yourself with an over-the-counter flea spray, or hire a professional pest control company. Over-the-counter sprays like Raid Flea Killer or Ortho Home Defense work on carpet and furniture. Follow the label instructions exactly — most require you to spray the entire carpet, under furniture, and along baseboards. Ventilate the apartment during and after spraying, and keep pets and children out of treated areas for the time specified on the label (usually a few hours).
Professional pest control is more expensive but more thorough. A technician will treat all areas of your apartment, including inside closets and under appliances. They use stronger products than what is available over the counter and often may provide results. If the infestation is severe or if over-the-counter treatment does not work after two weeks, professional treatment is worth the cost. Ask your landlord whether they cover pest control or whether you pay for it; some apartments include it in rent or require the landlord to arrange it.
Repeat treatment is often necessary. Most pest control services recommend a second treatment 10 to 14 days after the first to kill fleas that have hatched from eggs since the initial spray.
Prevent fleas from coming back
Once you have eliminated the infestation, keep your pet on year-round flea prevention. A monthly or quarterly prescription product from your vet is the most reliable way to stop fleas before they start. Even if your pet spends most of its time indoors, fleas can hitch a ride on your clothing or come in through open windows and doors.
Vacuum your apartment weekly and wash pet bedding regularly in hot water. Brush your pet frequently and watch for signs of fleas — scratching, small black specks in the fur (flea dirt), or tiny insects. Catching a new infestation early is much easier than dealing with a full-blown problem.
If you live in a multi-unit building, talk to your neighbors. If their apartments also have fleas, the building may need coordinated treatment. Fleas can travel between units through walls, vents, and shared spaces. Your landlord may need to arrange building-wide pest control rather than treating individual apartments.
Understand your rights and responsibilities as a tenant
In most places, landlords are responsible for pest control in common areas and for structural issues that allow pests to enter (like gaps around pipes or holes in walls). You are typically responsible for keeping your unit clean and for treating your own pet. However, lease terms vary, so check your lease or ask your landlord in writing who pays for flea treatment.
Some leases require tenants to pay for pest control; others include it as part of maintenance. Some landlords will not allow certain pesticides in the building. Getting permission in writing before you treat protects you from disputes later and ensures you use products your landlord approves of.
If your landlord refuses to address a severe pest problem that is affecting multiple units, you may have legal recourse depending on your state and local tenant laws. Document the problem with photos and keep records of when you reported it. Contact your local tenant rights organization or housing authority if the situation does not improve.
Frequently Asked Questions
How long does it take to get rid of fleas completely?
Most infestations are under control within two to three weeks if you treat your pet and apartment at the same time and repeat treatment as needed. Fleas have a life cycle of about two weeks, so a second treatment 10 to 14 days after the first catches any fleas that hatched from eggs after the initial spray. If you still see fleas after three weeks, call a professional pest control company.
Can fleas survive in a cold apartment?
Fleas prefer warm environments but can survive in cooler apartments, especially if they are in carpet or bedding where it stays warmer. Lowering your apartment temperature will slow their reproduction but will not kill them. Treatment is necessary regardless of temperature.
What if I rent and my landlord will not pay for pest control?
You can treat the apartment yourself with over-the-counter sprays or hire a pest control company and deduct the cost from rent in some states, though this is risky and varies by location. A safer approach is to ask your landlord in writing to arrange treatment, document their refusal, and then contact your local housing authority or tenant rights organization for guidance on your options.
Will flea bombs work in an apartment?
Flea bombs (foggers) can work but are less effective than targeted sprays or professional treatment because they do not reach under furniture or deep into carpet. They also require you to leave the apartment for several hours and can damage some items. Most pest control professionals recommend against them in favor of sprays or professional service.
Can I treat my apartment if I do not have a pet?
Yes. Fleas can enter an apartment on your clothing, on a visiting pet, or through open doors and windows. Treat your apartment the same way — vacuum thoroughly, wash all fabric in hot water, and use a flea spray on carpet and furniture. You do not need pet treatment if you do not have a pet, but you should still prevent future infestations by keeping doors and windows screened and vacuuming regularly.
