Performance. The small is not very nice .it's very dear for the bottle you get. You will have to buy three or four to do all the house 🏠.The speed was very good no it was great nice and early morning 😀 I did not have to wait all day long. The delivery diver was very happy 😊 and made my day we should have more people like this as delivery drivers 😀.

DO NOT BUY!!! it doesn’t work

The media could not be loaded. The bottle may as well contain water I have drenched fleas with the product and after about 10 minutes of the fleas being disorientated they’re fine and jumping back around I have used nearly all 5 L in two months and nothing has happened I am extremely disappointed with this product. The seller says it’s flea killer chemicals but it does not kill fleas. I gave us a few months just to see if it was slow acting. I have tried with multiple different fleas drown in them with the product and after about 10 minutes every single one still lives, this does not work. If I could give it negative stars I would as a review, I suggest you buy the Johnstons flea bombs they actually work on like this if it was possible to return the item and get my money back I would have it’s a scam and a waste of money I’ve killed more do them with my hands than the flea killer has also I’ve tried it with spiders it also doesn’t work it just makes me sneeze when I spray it

Doesn't eradicate what it says on label kills fleas but not the other things on the label

Works short term but doesn't kill all the things it says on lable
