Jason from Miami,fl writes,

Is Permethrin SFR 38.8% the best choice for killing ticks in the yard and in the house?

Does it have any residual effects, or only on-contact killing? Any effect on unhatched tick eggs? Can it be diluted for use on dogs as a spray or dip?


Permethrin SFR does have a residual effect and a good knockdown quality which is why it is very popular for tick control.  The residual can be expected to last for about 30 days.  The Permethrin SFR will not penetrate tick eggs, however once a tick hatches it is very susceptible to the Permethrin and should die very quickly.  Permethrin can be diluted for application on animals.  Please read the product label for full instructions on treating animals.
