I make the permethrin mix in the pump sprayer with the mineral oil. It works for the most part. Every now and then, especially when it is hot, then rain and then hot again. The ground serves as a virtual incubator. I spray the termidor on the ground as well as the pernethrin. Here in NC, because of the heat, the humidity and the rain they come in waves. I stay flea and tick free just about all the time then a wave will hit. I can have a dog with fleas on him and the dog next to him not have a one. It is a constant battle. I just bought a bottle of the Bayer Tree and Shrub and will make a run with it.

The Dursban is kick ass. It worked wonders around here for a number of years. The like all good products, they made them 'by licensed professionals only'. If you can use it in your area it worked well here. EWO
