Quick answer
Use a species-appropriate flea treatment on the pet, then vacuum daily, wash bedding at 60°C and treat the home environment for several weeks.
Treat your pet and home together to break the flea life cycle and stop re-infestation.
What you’ll need
- Tool: fine-tooth flea comb
- Tool: vacuum cleaner
- Tool: washing machine
- Material: vet-recommended flea treatment matched to species and weight
Materials
- Material: bin bag (to seal vacuum contents)
- Material: household flea spray or powder (if recommended)
- Material: white tissue (for flea dirt test)
Step by step
- 1
Confirm fleas with a comb and dirt test
Run a fine-tooth flea comb through your pet's coat, especially around the neck and tail base. Look for black specks that turn reddish-brown on damp white tissue — this is flea dirt, which is digested blood. Seeing live fleas confirms the infestation.

Treat the pet with a species-matched product
Apply a vet-recommended spot-on, tablet or collar labelled for your pet's species and exact weight. Read the label carefully. Never use a dog flea product on a cat; some contain permethrin, which is highly toxic to cats and can be fatal.
- 3
Vacuum thoroughly and daily
Vacuum all carpets, rugs, sofas and hard floors every day for at least two weeks. Pay attention to skirting boards, under furniture and pet sleeping areas. Eggs and larvae hide deep in fibres. Empty the vacuum cylinder or bag outside immediately after each session.

Hot-wash all bedding and soft furnishings
Wash pet bedding, your own bedding if the pet sleeps on it, and any washable throws or blankets at 60°C. This kills eggs and larvae. If an item cannot be washed, seal it in a plastic bag for two weeks.

Treat the home environment
Use a vet-recommended household flea spray or powder on carpets, upholstery and pet resting areas, following the safety instructions. Keep pets and children out of treated rooms until the product is dry.
- 6
Repeat treatments over several weeks
Flea pupae can lie dormant for weeks before hatching, so one treatment is rarely enough. Continue vacuuming daily and reapply the pet treatment according to the product schedule, usually every four weeks, until the infestation is fully broken.
- 7
Prevent re-infestation
Keep up with monthly preventive treatments on the pet, groom regularly with a flea comb, and maintain clean bedding and floors. Prevention is far easier than elimination.
Flea treatments contain pesticides that can harm pets and humans if misused. Never use dog products on cats (permethrin can be fatal), always match the dose to your pet's exact weight, and keep pets and children away from treated surfaces until dry. If your pet shows signs of poisoning (tremors, vomiting, seizures), contact a vet immediately. Call a professional pest controller if the infestation persists after 4 weeks of consistent treatment.
Common mistakes
- Treating only the pet and not the home, which causes re-infestation within days because 95% of fleas live off the animal.
- Using a dog flea product on a cat, which can cause tremors, seizures and death.
- Stopping after one treatment before dormant pupae have hatched, leaving the cycle intact.
Frequently asked
Can I use natural remedies instead of chemical treatments?
Natural options like diatomaceous earth or essential oil sprays may reduce flea numbers slightly, but they rarely break the life cycle. Vet-recommended products are the only reliably effective treatment for established infestations.
How long does it take to get rid of fleas completely?
With consistent treatment, you should see a dramatic reduction in 1–2 weeks, but full elimination usually takes 3–4 weeks because pupae can hatch after that long.
Why are fleas still appearing after treatment?
New fleas hatching from pupae in the environment will jump onto the pet until the infestation is fully broken. This is normal for the first few weeks; continue vacuuming and reapplying treatment on schedule.
Can humans get fleas from pets?
Human-adapted fleas are rare, but pet fleas may bite humans temporarily, causing itchy red bumps — usually on ankles or lower legs. Treating the pet and home removes the source.
How often should I treat my pet to prevent fleas?
Most preventive treatments are given monthly, but some last up to three months. Follow the product label or your vet's recommendation for your pet's species and lifestyle.
Can I bathe my pet after applying a spot-on treatment?
Avoid bathing or swimming for at least 48 hours after application so the product can distribute through the skin's natural oils. Check the specific product instructions.
