Query: Bio Spot is Crapola does not work at all!

Can you give negative stars?? Ugh Bio spot does not work, I had to wash him several times to get the fleas off him after I took him out thinking this would work he came back with a shite load of fleas. Don't fall for the line Oh it is only meant for light infestations and prevention. NO kidding that is why I bought it..! We are now treating the yard him and the house thanks Bio spot .
