What fully gets rid of fleas? A complete guide to eliminating fleas for good

One major reason infestations persist is that adult fleas make up only about 5% of the total population in your home. The other 95% are flea eggs, larvae, and pupae hiding in your environment. This means that killing visible fleas alone will not remove 100% of fleas. Find out where fleas hide in your house so that you can tackle the important areas with flea killer.

What actually gets rid of fleas completely?

To fully get rid of fleas, you need a combination of pet treatment, home cleaning, and environmental control. Here are the most effective steps.

These treatments kill adult fleas and prevent new flea eggs from developing. Many modern treatments also disrupt the flea lifecycle, which is key if you want to fully get rid of fleas, like vet-strength Itch Dog Flea Treatment and Itch Cat Flea Treatment which targets live fleas and flea eggs to stop ongoing infestations.

2. Wash all pet bedding and soft fabrics

Fleas love warm environments like pet beds, blankets, and cushions. To help get rid of fleas, wash all fabrics your pet uses like their bedding, any blankets and cushions they chill on.

It’s really important to wash on a hot wash (at least 60°C) and dry items if you can, on a high heat setting. This kills adult fleas and destroys flea eggs hiding in the fibres.

Don’t forget to repeat this process weekly until the infestation is gone.

3. Vacuum thoroughly and frequently

Vacuuming is one of the most effective ways to remove flea eggs, larvae, and adult fleas from your home. Focus on cleaning your carpets, furniture, cracks in flooring and skirting boards.

Constant vacuuming helps stimulate pupae to hatch, which helps treatments target them. Click here for the best vacuum cleaner for pet owners with fleas.

To fully get rid of fleas, vacuum daily during an active infestation and dispose of the vacuum contents immediately.

4. Use a flea spray or Insect Growth Regulator (IGR)

Standard insect sprays and general cleaning sprays like carpet cleaner may kill adult fleas but often fail to stop the lifecycle. For the best results, use products that contain insect growth regulators (IGRs). These prevent flea eggs and larvae from developing into adults.

IGRs work by stopping flea eggs from hatching ➡️ Preventing larvae from maturing ➡️ Breaking the flea lifecycle

When combined with cleaning and pet treatment, this approach can eliminate 100% of fleas in most homes. Don’t try to cut corners, use a treatment that is vet-approved and effective like the Itch Flea House Spray which kills fleas, eggs and larvae for up to 2 months after one blast.

How to use a household flea spray? 

Always see instructions on the product, but usually spray around an arm’s length from the target spot and make sure to leave the room vacant for 30 minutes. Ventilating afterwards can help reduce the toxicity too.

Where should I use flea spray in my home?

Because many flea eggs fall off pets and land in carpets, these areas often contain the largest flea populations. We;d also recommend any furniture that can’t be washed, floorboards and skirting boards, as well as doormats. 

Try to leave the treatments long enough to reach deep into carpet fibers or cracks where flea eggs and larvae hide. Remember, consistent treatment is necessary if you want to completely get rid of fleas.

6. Don’t forget outdoor areas

If your pets spend time outside, fleas may also be living in your garden. Outdoor flea hotspots tend to be shaded soil, garden beds and underneath decking.

The best way to remove fleas from your garden is to keep your grass trimmed and use outdoor flea treatments if your infestation is severe. There are plants that can help steer away fleas and other pests, such as catnip and lavender.

Why do my cat’s or dog’s fleas keep coming back?

Many people think their flea treatment failed when fleas reappear after a few days. In reality, new fleas are usually emerging from previously hidden flea eggs and pupae.

This is why flea control takes several weeks.

Even after treatments:

• Flea eggs may still be present
• Pupae can remain dormant
• Newly emerged fleas may appear

Consistent cleaning and treatment ensure that every stage is eliminated. But it can be difficult to get a hold on fleas and sometimes cleaning every week doesn’t quite cut it. Get the big guns out and eradicate fleas fully from your pet and home, with the Itch Flea Eradication Kit to Get Rid Of Fleas, fast.

How long does it take to get rid of fleas?

Most infestations take 2–4 weeks to fully eliminate.

Flea eggs to hatch ➡️ Larvae to emerge ➡️ Pupae to develop and become vulnerable

With the right approach, you can eliminate 100% of fleas during this period. Stopping treatments too early is one of the main reasons fleas return.

So what fully gets rid of fleas? The answer is targeting every stage of the flea lifecycle, not just the adult fleas that you can see. You can’t snap your fingers and wake up flea-free, but with a consistent and determined approach you’ll say goodbye to fleas, once and for all.
