Permethrin 10% mixed in Bayer tree and shrub to kill fleas and ticks

[wfk1]

Has anyone tried this? I was told to mix 3cc of the permethrin 10% in a 40oz bottle of bayer and put 2-3 oz down their back.worked for the fleas but not the ticks.just wondering how much more permethrin i could put in and still be safe?

Permethrin works to kill fleas for short term, it also helps repel sketters. I ussually mix six oz in a two gallon pump up sprayer and spray them down with it. Not sure how much you would apply directly though.

I would ask a chemist when you start mixing chemicals like that!
