Flea control: how to spot fleas, costs and treating your home
Flea control is more than treating your cat or dog. The cat flea, which also lives on dogs and bites people, lays its eggs on the pet, but they fall off into carpets, the sofa, the pet bed and gaps in the floor. Larvae and pupae develop there, and only a small part of the flea population is actually on your pet. If you treat the animal alone, new fleas keep emerging from the pupae and the problem starts all over again.
In this guide you will read how to recognise fleas in the house, what you can do yourself, when professional flea control is needed and roughly what it costs in 2026. You will also get tips to prevent a new infestation. If you need help right away, see the top 3 pest controllers in your city.
Recognising fleas: bites, flea dirt and the sock test
A flea is 2 to 3 millimetres long, dark brown and flat, and jumps away as soon as you come close. The first sign is often a pet that scratches or bites itself a lot, especially at the base of the tail and the neck. Comb the animal over a sheet of white paper and black specks fall out: flea dirt. Wet them; if they turn reddish brown, it is digested blood. On people, flea bites appear as small itchy bumps, usually around the ankles and lower legs. To find out whether there are fleas in the floor, do the sock test: walk around the room in white socks for a few minutes and see whether dark dots jump onto them.
Flea control: DIY or call a professional?
With a light infestation you can tackle fleas in the house yourself, as long as you do it thoroughly. Always start with your pet: a flea product for cats and dogs is arranged through the vet, who chooses the right product and dose. Wash pet beds, blankets and bedding at 60 degrees and vacuum carpets, the sofa, gaps and skirting boards daily; the vibration lures fleas out of the pupae so they get caught after all. If it has not worked after two to three weeks, or if fleas appear in large numbers after the house has stood empty for a long time, choose professional flea control. In the Netherlands, professional biocides, which also work on the larvae and pupae in the floor, may only be used by pest controllers with a professional competence certificate (KPMB). The pest controller does not treat the pet itself; that remains the vet's job.
How a professional flea treatment works
A professional starts with an inspection: which rooms are infested, where does the pet sleep and where are the hotspots? They then treat floors, carpets, skirting boards and the animal's sleeping places with a residual product, often combined with a growth regulator that stops larvae developing. Because the pupae are well protected by their cocoon, a second treatment follows after 2 to 3 weeks to kill the fleas that have emerged since. You receive instructions in advance, such as vacuuming and leaving the house with your pets for a few hours during the treatment, and afterwards you do not mop the floor for a while so the product keeps working. A good pest controller follows IPM and combines the treatment with advice on the pet, washing textiles and vacuuming, because without those steps the infestation returns.
Flea control costs: what you pay in 2026
As an indication, professional flea control in 2026 costs €150 to €300 for a home, including VAT. For that you usually get two treatments 2 to 3 weeks apart, including inspection and advice. The price depends on the size of the home, the amount of carpet and the severity of the infestation. With a stubborn infestation or a large house, an extra treatment may be needed. Treating your cat or dog is not included: you arrange that separately through the vet. Ask in advance what is included and whether a guarantee is given.

Preventing fleas: pet, textiles and vacuum cleaner
Prevention starts with the pet. Give cats and dogs a flea product all year round as advised by the vet, including in winter, because fleas stay active in a heated home. Wash pet beds and blankets regularly at 60 degrees and vacuum carpets, the sofa and the animal's sleeping spots every week. Check your pet with a flea comb after a stay in a boarding kennel or contact with other animals. Keep hedgehogs, stray cats and other wildlife out of the shed or garage where you can, because they bring fleas. If you move into a home where pets lived before, vacuum thoroughly before moving in; pupae can wait for months for vibration and warmth.
