yeah sounds like you have a real good infestation of them little buggers . the pills and all are great FOR THE DOGS but they do nothing to kill out an infestation in your yard and kennel or your house ect. ect. that is why I am religious in the warm months with the spraying regiment . at the moment you probably have hundreds of new fleas hatching daily . but the permethrin will kill the adults and the martins will sterilize the newly hatched fleas before they get to the biting and egg laying stage . once you break the hatching cycle you will be able to control them easily enough with a regular spraying . I mix some permethrin in a small spray bottle and spray my pants legs before I go out walking around in the summer months to keep the chiggers and ticks off of me works great as well as for spraying the dogs ears when the flies are bad . as bad as you seem to have them you could also get you some spectricide with the hose end sprayer [ bottle you hook to your water hose ] and spray you whole yard down as well .
they are horrible halfbreed it happened fast too. I'm thinking about calling an exterminator. I'm gonna keep spraying and spraying and try to kill em all.
