    Top 10 Best Home Flea Sprays, Foggers and Powders Reviewed

    Virbac Indorex Defence Flea Spray

    The bestselling home flea treatment available, with a host of glowing 5* reviews and success stories from users.

    In order to break the lifecycle of a flea infestation, the home needs treatment too. This is a household insecticide spray which kills adult fleas and stops eggs and larvae developing further. It acts on contact as opposed to ingestion like the flea treatment you may use directly on your pet.

    Adult fleas will be killed for up to two months so it is long-lasting to ensure the issue disappears. Eggs and larvae will be prevented from developing for up to 12 months which makes it one of the most effective on the market.

    Dust mites are also gone, which are a common allergen with dogs in the home and can further cause itching. Spray it directly on to carpets, rugs and other hard and soft potential flea areas, and close off and ventilate the room for around an hour.


    • Top seller
    • Relatively short time wait after use


    • Type: Aerosol Spray
    • Capacity: 500ml
    • Dimensions Covered: 79 sq metres

    Beaphar Household Flea Powder

    If potentially airborne sprays and foggers are not suitable as you or your pet have respiratory issues, a powder could work.

    The sprinkle-on formula acts as a carpet cleaner, being left to work its way in before needing to be vacuumed. It kills fleas and the larvae and also absorbs pet odours to leave your room and furnishings smelling pleasant.

    It should mostly be used on rugs and carpets, so can be used alongside sprays if you need to also tackle curtains or sofas. Don’t use on wet areas, and preferably leave for up to an hour so it has time to work deep into the carpet pile.

    You should use it alongside on-pet flea treatments, but it can be used regularly if you have multiple pets and want to double-check that your home is completely pest-free.


    • Good for deep-pile carpet areas
    • No airborne particles
    • Targetted results


    • Type: Powder
    • Capacity: 300ml
    • Dimensions Covered: 10 sq metres

    Vetkem Acclaim Household Flea Spray

    This spray kills adult fleas on contact and prevents eggs and larvae from growing into adults.

    You can repeat the application every seven days to give you a chance to monitor the situation, but it will last up to 12 months after application. It can be used in any areas in the home where you feel fleas may be, and in outbuildings and in the car if your pet has frequented these areas.

    Remember that fleas can jump quite far and travel on humans, so it is best to cover as much area as possible. Acclaim is strong stuff and one of the most popular options in America, so it will get rid of the critters in no time.


    • Vet approved
    • Easy to use
    • Also kills dust mites


    • Type: Aerosol Spray
    • Capacity: 500ml
    • Dimensions Covered: 80 sq metres

    Johnsons 4Fleas Room Flea Fogger

    When you are facing quite a serious infestation and the only way forward is to spray the entire room top to bottom, a flea fogger may be the best option.

    4Fleas can protect the room for seven months after application, ensuring no eggs or larvae develop into adult fleas and that pupae will die once hatched. It contains an insect growth regulator (IGR), a substance that stops the life cycle of an insect.

    You simply place it into the room on a raised area, press it until it locks and then leave, closing doors and windows behind you. You can open any interior cupboard doors for full treatment, which makes it better for full coverage than sprays.

    It will only treat exposed surfaces though, so under furniture will need to be tackled manually with sprays. Leave the fogger to work for two hours and then air the room for a further 30 minutes.

    The mist shouldn’t stain any soft furnishings, and it can be repeated with a second application the next day if the issue seems to be very severe.


    • Complete room treatment
    • Also kills ants, cockroaches and earwigs


    • Type: Fogger
    • Capacity: 2 x 100ml
    • Dimensions Covered: 35 sq metres

    Strikeback Flea Killing Spray

    This trigger spray is part of the Strikeback range, which gives longlasting results and is suitable and approved to use in the workplace and other sensitive places.

    It keeps working up to 12 weeks after application, which is ideal if you’re going to have a lot of work on your hands to get rid of the beasts. It’s colourless and odourless, and so can be used in living areas as well as on bedding.

    Just keep everything well ventilated, and be aware to keep cats well away.


    • Safe to use in sensitive areas
    • Large bottle


    • Type: Trigger Spray
    • Capacity: 1L
    • Dimensions Covered: Various

    ARDAP Fogger Flea Fumigator

    Able to tackle any flies, bugs and insects such as fleas, ticks, mites which may be bothering you and your pet.

    It contains permethrin, which quickly and reliably kills the vermin, and pyriproxyfen, which breaks the biological development cycle of the insects. This means that fleas of all life stages are eradicated.

    It also means your home is protected for around six months. The can is emptied within a few minutes of activation, so it gets to work quickly. One can of fogger covers 30m2, so there is enough in this package to do two rooms.

    The room should be left for two hours, and then ventilated for a further hour. It leaves a nice citrusy smell behind and doesn’t leave a residue.


    • Covers a good-sized area
    • Nice smell left behind after ventilating


    • Type: Fogger
    • Capacity: 2 x 100ml
    • Dimensions Covered: 30 sq metres

    Karlsten Flea Killer Spray

    Karlsten offers treatment sprays for ants, bed bugs, moths, spiders and fleas, so they know what it takes when it comes to eliminating critters.

    It creates a bug barrier, killing fleas and stopping them from being quite so active and jumpy in your home. This lasts for six weeks, so any more which come in won’t make a home in your carpets either.

    It’s been tested by the UK’s Health and Safety Organisation, so passes all legal issues, and is odourless so you won’t be able to smell chemicals for weeks after use. The Karlsten spray is also humane and one of the few which specifically targets fleas as opposed to other bugs, which is good if you don’t also want dead spiders and flies when you go into the room.


    • Only targets fleas (humane)
    • Thoroughly tested


    • Type: Trigger Spray
    • Capacity: 500ml
    • Dimensions Covered: N/A

    CritterKill Professional Strength Flea Smoke Bomb

    A form of fogger, flea bombs are often more on the professional scale versus spray foggers – for those who really have tried everything else.

    This one contains 15 grams of Permethrin, which is a very high dose compared to other options on the market. Flea bomb usage should not be taken lightly as it can rule the use of your room out for a really long time, and this CritterKill was previously only for professional controlled use – so you know it is strong stuff.

    The smoke will kill most insects on contact, and rooms must be left untouched for at least four hours (although they recommend much longer). You can repeat as necessary in two or four-week cycles to remove any recently hatched fleas which were at the pupae stage previously.

    It is good when used alongside sprays beforehand, which can offer more targetted results on areas where your pet may favour such as the sofa or around their bed. Also bear in mind that they will set off any smoke alarms so disable these first. Place on a fire-safe surface and don’t leave your home unattended.


    • Available in 2, 4, 6, 8 or 10 packs
    • Strongest on market
    • Doesn’t leave behind ash or residue


    • Type: Flea Bomb
    • Capacity: 15g
    • Dimensions Covered: 50 sq metres

    Vet's Best Flea Tick and Mite Flea Treatment Spray

    This spray can be used both in your home and on a dog’s coat (although we don’t recommend the latter due to lack of effectiveness and the residue). Despite not being for cats, it is still safe to use on home furnishings.

    But it is natural, which may be vital for you if you don’t like to use harsh chemicals or have an aversion to ingredients commonly used. It’s a trigger spray too, so can eliminate the risk of airborne particles by offering more targetted liquid spraying.

    It contains Margosa, Citronella, Eucalyptus and Peppermint. These all have their own job and can repel fleas as they don’t like the smells, so is a bit more humane.

    If you want a product you can use outside on plants and patio areas for full flea coverage this could be ideal, as it won’t harm your plants or other wildlife.


    • No chemicals
    • Also protects against mites and ticks


    • Type: Trigger Spray
    • Capacity: 500ml
    • Dimensions Covered: N/A

    Zero In Flea Killer

    A bit of a bonus product. Not a spray, bomb or fogger like the others on the list, but rather a natural, electronic pet mimic (which is more sensible than it sounds).

    Chemical-free, odourless and safe to use around children and pets (so you don’t have to cut off the room), it attracts fleas via a 7W heat lamp. Fleas love warmth, which is why they prefer your pet’s soft fur to your bare skin.

    This heat lures them in, where they become trapped on the sticky disc which is at the base. For the best results, it should be used near an area which your pet frequents such as close to their bed.

    Each disc lasts for a few weeks, but regular changing offers the most effective results. It comes with three discs and there are refills available, so you can use all year round and not just for temporary measures. If used 24/7, it could also act as a first-step sign to the presence of fleas on your pet before the itching starts.

    It isn’t going to tackle room-wide problems but can keep fleas away from pet beds and other areas which you are finding hard to continually wash. Bulbs will last for around three months with constant use, which should be long enough to tackle any issues.

    Bear in mind it is mains-operated so will cost a bit of money to run and isn’t good for pets who chew wires.


    • Poison-free
    • No need to close off the room
    • Can be used year-round


    • Type: Electronic
    • Capacity: 3 Discs
    • Dimensions Covered: 10 sq metres

    Buying Guide

    Types Of Home Flea Eradicator

    There are various ways in which you can get home flea treatments, which may suit some lifestyles or levels of severity best:


    Perhaps the most widely available form, and the one which is least likely to disrupt your home life too much. They come in aerosol and trigger options and can be sprayed anywhere that is needed as and when needed. Sprays usually kill fleas at all life stages and can be used as often as needed. They’re best for targetted action as opposed to a room-wide solution

    Fogger Sprays

    Also known as ‘fogging’. You leave these in a room, press the trigger until it clicks, leave the room and then what is released disperses throughout the closed area. They offer more coverage than other forms, getting to where you can’t, but are inconvenient as the room is often out of bounds for a few hours for human and animals, so they are for the most serious cases usually. It is what a pest controller would use first

    Flea Bombs

    A form of fogger, except you light it like a candle as opposed to spraying with it. This releases smoke, which may be better for some people who can’t have liquid particles around

    Electronic Devices

    Usually seen as the least effective option, but can be good to leave by a small area your pet regularly frequents such as a bed. They give out heat and light to attract the fleas, which then stick to pads which they can’t jump off. Good as a signal to if your pet has fleas

    Killing vs Repelling

    What do you want to achieve? Flea treatment can do one of two things – kill the fleas at all life stages, or repel them from going on certain areas.

    If your issue isn’t severe, repelling them could do the trick and vacuuming or steaming them could tackle the issue. But serious cases will likely need something stronger to ensure they all disappear.

    Fleas aren’t anyone’s favourite animal, but you may still be against killing them.

    Natural vs Synthetic

    Natural flea repellents and products are often not recommended as they aren’t as effective and often repel as opposed to killing.

    Synthetic sprays are best, but the obvious risk of chemicals is present and you may wish to avoid them. Always look at ingredients lists and educate yourself before jumping in. Pyrethrin is very potent,

    Natural options can be better for anyone with breathing issues, or anyone with elderly pets or children.

    Cypermethrin and Cats

    This is an ingredient found in a lot of the above insecticides. It is a synthetic pyrethroid which acts as a neurotoxin on insects.

    It is very toxic to cats, who cannot tolerate the therapeutic doses made for dogs. UGT1A6 is the enzyme responsible for metabolising the ingredient, and exposure to cypermethrin causes a deficiency in it.

    It remains much longer in cat organs compared to dogs and can be fatal in larger doses, so if you have cats, increase the recommended wait times before you allow them into the room. You may also want to fully vacuum or steam/wash appropriate surfaces after the use of the insecticides.

    The pyrethroid also has shown a toxic effect on rats and other small animals, so do the same with these. Lastly, it is highly toxic to aquatic mammals, so remove fish tanks before using flea sprays.

    If you are worried about these issues, opt for a treatment which doesn’t contain the ingredient, but when used safely and following strict guidelines, it shouldn’t have a negative effect on animals.

    Other Buyers Ask...

    Which Repellent Is Best For Me?

    In the vast majority of cases, sprays which can be used directly on surfaces are best and should be where you start the fight. Fleas are not airborne creatures, so airborne foggers can be a step too far in most cases.

    But if your infection is severe, you may need a fogger or smoke bomb to clear all areas, such as high up on curtains, just as a precaution.

    What Else Do I Need To Do To Get Rid Of Fleas?

    Persistence is key, and so is treating your dog effectively, washing soft furnishings and regular vacuuming and steaming carpets and surfaces.

    Vacuuming is vital as no insecticide can kill off fleas at the pupa stage, so hoovering regularly over the course of seven days should get all last traces remaining. You may also wish to reapply repellents after this time.

    Before applying any of the above, you should remove all washable surfaces like cushion covers and bedding and wash on high heat for the best results.

    Ensure your dog is protected with topical or tablet treatments before releasing them back into the room.

    Check out our guide on how to get rid of fleas on both your pet and in your home.

    When Should I Use Flea Sprays And Bombs?

    These should be used when you are sure or suspect there are fleas in your home, such as clues from your pet or if you are being bitten.

    They can also be used as a preventative measure every so often, such as monthly at the same time as the reapplication of spot-on topical treatments for your pet. Summer is a particularly vital time to protect your home when the weather is hotter and fleas are more prominent in the heat.

    You need to pick a good day where you can leave the house for a few hours and also leave windows and doors open after about an hour to air the room and free it of any leftover smell or airborne chemical particles.

    Fleas can still come into your home even if your pet is protected. For some pets which use topical treatments, they can carry the fleas but it is only when the flea bites that they die. This can mean that fleas come into the home, and end up in your carpet where they lay eggs and begin a life cycle.

    Where Should I Spray?

    If using an aerosol or trigger spray, some important areas to cover are:

    • Carpets
    • Rugs
    • Curtains
    • Sofas and chairs
    • Cushions
    • Skirting boards and other areas which contact the above
    • Around door frames
    • Underneath furniture
    • Outside areas (like outbuildings, patios and decking, especially in warmer months)

    As with any product, do check that it is suitable to use on all of the above before using. You may need to use a few different products to cover the whole house.

    Can I Use Flea Repellents On My Mattress?

    Does Fido also sleep on your bed? You’re probably waking up with chewed ankles in the morning.

    Not all of the treatments above can be used on mattresses or dog beds. Most flea treatments contain insecticides which cannot have contact with skin or be breathed in huge amounts.

    As mattresses and some dog beds can’t be washed, this repellent can’t be gotten rid of so could cause some issues. Try to buy a natural repellent if using somewhere like this, and choose steaming and vacuuming.
