## Description

Flea Killer Spray 2.5L | Cypermethrin-Based RTU Treatment for Indoor Use | Fast-Acting, Long-Lasting Protection | Insect Spray for Commercial Properties, Hotels, Warehouses & Home Use : desertcart.co.uk: Garden

Review: Love - 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
Review: IT WORKS - We didn't like the gun attachment to the 2.5L bottle it was a bit heavy to hold and spray at the same time, but we decantered it into another spray bottle and found it much easier, there was no smell coming from the liquid which was a plus. It seems to have done the trick as dogs have stopped scratching, we thought it was value for the money and would buy it again.
