This household flea spray has been extremely efficient and very effective. It is great for all around the house.
If you use this on carpets then I would advise to first hoover the carpet quite roughly and then apply the flea spray because then any flea larvae or eggs will be disturbed, meaning you can catch them with the spray after hoovering as flea eggs and larvae are known to have a protective coating, quite freaky of nature to be fair but they do, so that's how we've got them under control and by breaking the protection the fleas have means the spray can get the ones hiding including larvae/eggs.
Using a hoover you need to make sure you clean out the hoover outside the house and also give a spray of the flea spray directly into the hoover compartment itself if bagless - Or If it's a bagged hoover just bin the bag and put in a new one and spray. (ours is bagless).
Make sure your pet has been flea treated first for the best effect, but if not yet treated then still get the spray if you are waiting for an appointment or for treatment as you can get a good head start on combatting the fleas
Fleas are a nightmare, but if you sooner rather than later then you can get it under control.
