Review: The Only Thing That Worked After Weeks of Trying Everything - After many many weeks of dealing with a persistent infestation and multiple pest control visits, this spray is the only thing that actually worked. I’ve tried several products (some recommended by professionals), but nothing had a lasting impact — until I used this spray with cypermethrin. What really impressed me is how fast and effective it was. I sprayed key areas like door thresholds, floors, and balcony access points, and within hours the difference was noticeable. I followed the instructions, let it dry fully, and I haven’t had a single new bite since. Works better on hard surface than soft furnishing, although I used on carpets and bed as well, following this all are dead. Even pest control confirmed it’s a solid product — and honestly, I now keep it as my go-to backup. The fact that it contains cypermethrin, just like professional treatments, makes it ideal for treating areas between visits or when professionals miss spots. Easy to use, strong smell use mask, dries fast, and most importantly — it works. I highly recommend this for anyone who’s fed up with ineffective sprays and wants proper peace of mind.
Review: Very strong - Very strong it made me cough a lot Don't use if you have Asthma or breathing problems The pump don't work very well and it's a very small bottle for the price I just hope it works and does the job

### ⭐⭐⭐⭐⭐ Love
*by C***Y on 23 December 2025*

Worked like a dream. We come home from holidays a few months ago and when we got back we found our house was infested with fleas and I mean we were covered as soon as we entered. Our dog was already on medication to help keep them at bay and before going on holidays there was no signs so was baffled but we sprayed this and within the week we were flea free again and have been for months now. Kept up with regular cleaning but I completely recommend. Doesn't smell nasty either
