Ethical and safe way to defeat fleas/ticks
I bought this product in the hope that it would be effective against fleas and ticks. I've stopped using spot on or flea/tick tablets as I believe these products are harming our fur babies. If by sucking blood from your pet kills these bugs what are these toxins doing to our pets liver and kidneys????. Any how, this product is amazing. I live in the countryside and on each walk there would be a tick attached to my dogs after our return home. Since using this spray not one tick has attached itself to any of my four dogs. No sign of fleas either. The bottle has an easy trigger and emits a light mist which I comb through. I apply it twice a week to each dog. It has a lovely natural scent. When buying it there was also a discount. An exceptional product, good value for money and gives me piece of mind knowing my babies are protected but they're not being harmed by toxic chemicals. A win win all round. Would highly recommend. Will be buying more....

Smells nice
Don’t think it actually repels fleas , but stops my dog from itching instantly when he’s had fleas , I’m on the second bottle now , the spray wasn’t working wery well so I unscrewed it and the pipe was too long and was blocked , I cut the pipe to proper length and cleared the blockage ,hey presto ! Perfect spray

Effective
Rather a strong smell, not unpleasant but does linger. Appears to be working but have only had it a few days. Service from buyer was very good but let down by delivery driver. I have no front garden but he didn't ring the door bell he just left the parcel by the door had I not have been looking out for him it would have probably been stollen. Shame as I won't be ordering from this seller again due to the delivery.
