How to get rid of fleas in the house - fast!

Seen fleas around the house? Been bitten on the ankles? Or has cuddling your cat or dog left you with little red spots on your lap? We’re sorry to tell you, but these are signs of a flea infestation. As pet parents it’s hard not to panic when we hear this news, but don’t worry. Just follow our experts’ simple steps to get rid of them.

1. Treat all pets for fleas

Even if the little pests have only been spotted on one pet, all cats and dogs in the house need to be flea treated (if they haven’t been already) or the problem won’t be fixed.

Regular treatment of all pets at the recommended interval is key to keeping our pets protected from fleas. Any breaks in treatment give fleas a chance to live, breed and grow in numbers, and that’s when an infestation happens. 

When choosing a flea treatment in future, it’s good to remember that some only kill fleas on pets, while others can also stop the eggs fleas lay from developing any further – and that will help avoid more infestations.


2. Regularly vacuum everywhere your pet has been

Seeing adult fleas unfortunately means there will be flea life stages (eggs, larvae and pupae) around the place, waiting to develop into new fleas.

So, it’s time to get busy with that vac wherever your pets go. Hard floors, furnishings, the car, carpets and rugs – they all need doing.

This does two things. The warmth and vibration help new fleas to hatch out – they’ll then jump on a treated pet and be killed by the treatment. Plus, it vacuums up some of the flea life stages. Remember to empty the vacuum cleaner afterwards!

3. Wash pet bedding

As flea eggs scatter wherever our pets go, somewhere they lie or sleep is going to be infested with flea life stages. If possible, wash these items at 60°C to help remove some of the problem.

4. Allow pets access to all their usual places

The good news is, a flea-treated pet is going to help resolve the infestation rather than make it worse. So, let them go wherever they usually do. Fleas will hatch out and jump onto your pet, where they’ll quickly be killed by the flea treatment on them – within 24 hours if you’re using FRONTLINE PLUS® or FRONTLINE® SPOT ON, or within 6 hours with FRONTLINE TRI-ACT® for dogs. This is why in a flea infestation situation, you’ll see fleas on your pet even after they’ve been treated – you’re spotting the new flea arrivals before they die.


5. Use a household spray

Sprays like FRONTLINE HOMEGARD® can be used throughout the home to help kill fleas, eggs and larvae found there and get on top of a home infestation more quickly. Household sprays should never be used on pets. Remember to spray places like under furniture, inside the vacuum and in the car.

Taking these steps helps fight a flea infestation faster, but it takes time for an infestation to tail off as we have to wait for all the flea pupae to develop into new fleas before the infestation is over (no chemical can kill flea pupae). This can take three months or sometimes longer, depending on the heat and humidity, and the amount of CO2 and vibrations from us and our pets.

It’s also important to know that an infestation can seem to get worse before it gets better. That’s because the flea life stages already in the home are developing and hatching out. Don’t lose faith – if your pet is regularly treated and you’ve sprayed your home, the infestation will be on its way out.
