Effect flea killer
Bought this because the cats' flea drops seem to have been ineffective this past year and I needed something to spray on carpets and floors. Easy to use, scent not overpowering and it gets rid of the fleas, which stopped jumping on me.

The best stuff!
Only thing I'll use for this purpose. I spray our flat fully, twice a year with this regardless. Instantly see spiders, flies, anything you didn't know was lurking, fall to windowsills. We used to have cats and our neighbours have pets so we just do it precautionary to avoid unwanted pests!

Very good product
Brilliant product, I would have given 5 stars but for the slightly unclear instructions on the tin, it doesn't state how long to leave the room for after spraying, i had to look on the internet for details and i found out you spray the room, leave for 30 minutes then ventilate and leave for another hour before using that room again and you should also vacuum where youve sprayed to remove any unsettled particles .. the product itself i cannot fault. I used this as a preventative rather than a cure as a neighbours cat that visits us had quite few passengers on him so i sprayed the house with this just to be safe. The unfortunate consequence is that it kills everything, spiders, woodlice, moths, anything that touched it it would seem. so i can definitely say if there were any fleas it would have killed them too. Smells quite strong and chemically, as you would expect for a product of this nature but dissipates quickly once the windows are open. Didnt leave any visible residue on the laminate or tiled floors and all fabrics i sprayed it on were unaffected.

The ONLY spray that works!!
After 15yrs of cat ownership, I had my first case of cat fleas! They are indoor cats. After using the appropriate Spot On treatment on my cats, I treated my whole house with this spray. Spray every single nook, every corner, behind furniture - EVERYWHERE! From reading others' experience with the nightmare trying to get of fleas, I thought this would be an ongoing issue for months.. Thankfully 4 weeks later we are flea free! I hoovered 2x daily, sprayed this after every hoover session. You really have to be thorough and consistent. I now use this once a fortnight for maintenance and treat my cats monthly too. It's been a couple of months and no more fleas.
