How to Get Rid of Fleas in Your Home
Start here
To get rid of fleas in your home, you have to hit them on two fronts at once: treat every pet with a vet-recommended flea product, and clear the eggs, larvae and pupae from your environment by vacuuming thoroughly, washing all bedding in hot water, and keeping it up for several weeks. Only about 5% of a flea infestation is the adult fleas you see — the rest is hidden in your carpets and furniture, which is why one round of treatment is never enough.
Why fleas are so hard to clear
The fleas hopping on your pet are the tip of the iceberg. The vast majority of an infestation — eggs, larvae and cocooned pupae — lives in your carpets, bedding, upholstery and floor cracks. Pupae are especially stubborn: they sit protected in cocoons that resist sprays and can hatch weeks later when they sense warmth and movement. That's why fleas seem to "come back" after you thought you'd won.
Practical take: Clearing fleas is a marathon, not a sprint. Plan for consistent effort over 8–12 weeks rather than a single deep clean.
Step 1: Treat every pet in the home
Use only species-appropriate products. Never apply a dog flea product to a cat — many contain permethrin, which is toxic to cats. Dose by weight and follow the label.
Start with the source of the eggs: your pets. Treat all dogs and cats in the home at the same time with a vet-recommended flea preventive, even ones that seem unaffected. Adult fleas on your pets are laying eggs that fall into your home, so stopping them stops the resupply. See our guides on fleas on cats for cat-specific products.
Step 2: Vacuum everything, often
Vacuuming is the single most effective home step — it removes eggs, larvae, flea dirt, and even stimulates pupae to hatch so treatments can reach them:
- Vacuum daily at first: carpets, rugs, hardwood, tile grout, along baseboards, under furniture, and upholstery.
- Don't skip the edges and cracks where larvae hide from light.
- Empty the canister or discard the bag outside immediately after each use, since fleas can survive inside.
Step 3: Wash and treat soft surfaces
Fabric is where eggs and larvae thrive:
- Wash all pet bedding, blankets and washable covers in hot water and dry on high heat. Repeat weekly.
- Wash your own bedding if pets sleep on your bed.
- Consider a home treatment — an EPA-registered household flea spray or fogger containing both an adulticide and an insect growth regulator (IGR), which stops eggs and larvae from developing. Follow label safety directions and keep pets and people away as instructed.
| Method | Reaches | Notes |
|---|---|---|
| Vacuuming | Eggs, larvae, some pupae | Do daily; empty outside |
| Hot wash + dry | Eggs, larvae, adults in fabric | Bedding weekly |
| IGR products | Eggs and larvae | Prevents new adults maturing |
| Pet treatment | Adults on the pet | The ongoing source |
What doesn't work (skip these)
Plenty of popular home remedies waste time or cause harm:
- Salt, baking soda or diatomaceous earth alone — messy and unreliable, and dust can irritate pet and human airways.
- Essential oils — many, including tea tree oil, are toxic to cats and dogs.
- Flea bombs as a stand-alone fix — they miss protected pupae and shaded spots and won't work without treating the pets and vacuuming too.
Stick to the proven combination: treat pets, vacuum, wash, and use an IGR-containing product if needed.
Preventing a repeat infestation
Once you're clear, keep it that way:
- Keep every pet on year-round flea prevention — this is the most important long-term step.
- Vacuum regularly and wash pet bedding often.
- Treat the yard if your pet spends time outside and reinfests.
- Check pets with a flea comb periodically so you catch a new problem early.
Logging when you last treated each pet and cleaned makes it easy to stay on schedule and confirm the infestation is truly gone rather than dormant.

Frequently asked questions
How long does it take to get rid of fleas in the house?
Because eggs and pupae keep hatching, expect to treat pets and clean consistently for about 8 to 12 weeks to fully break the cycle. You'll see far fewer fleas within days, but stopping too early lets a new generation restart the problem.
Do I have to treat my house if I treat my pet?
Yes. Only a small fraction of an infestation lives on the pet — most eggs, larvae and pupae are in your carpets and bedding. Treating the pet alone leaves the environmental population to keep reinfesting them.
Does vacuuming really get rid of fleas?
Vacuuming is one of the most effective home steps. It removes eggs, larvae and flea dirt and even prompts protected pupae to hatch so treatments can reach them. Vacuum daily at first and empty the contents outside right away.
Are flea bombs or foggers enough on their own?
No. Foggers miss pupae in cocoons and any shaded or covered areas the mist can't reach. They only help as part of a plan that also treats every pet, vacuums thoroughly, and washes bedding. Choose products with an insect growth regulator and follow safety directions.
Are natural flea remedies safe and effective?
Most are neither. Salt, baking soda and diatomaceous earth are unreliable and can irritate airways, and many essential oils, including tea tree oil, are toxic to cats and dogs. Stick to vet-recommended pet products and proven cleaning steps.
