Just tried Bifen. It seems to be working well. I got it from a 'treat your own home' site but I believe it is on EBay as well.

It seems most everything I have ever tried has worked, to an extent. There are pines all around the dogs so it is a constant battle. I can keep them at bay for the most part, but there will be the occasional outbreak. Usually just one dog out of the yard. I bathe and treat the dog then the area. Then do what it takes to keep them at bay all over again.

Here in NC it is a never ending battle. 90 degrees, followed by a rain shower, the humidity soars and the temperature gets back into the 90's....the perfect incubator. EWO
