Bayer tree and shrub quit workin for me....dawn is great to kill the fleas on the dogs but will not hold residual to keep killin the ones that jump right back on em.
Take some of this mix it with some vegetable oil in a pump sprayer to make it stick better.
It will smoke fleas and their buddies wives too. Cost ya around 14 bucks and will do a twenty or more dogs with pissed off veitcong sand fleas with no passports carrying AK's.

I have this and the Bayer and neither of the two work whatsoever.. Maybe I had a bad infestation but the only thing that thought about working was the Comfortis. I even bought the Permithrin SFR(high dollar crap) and it helped but they were back in full force within 2 weeks..
