in response to catandwoman... My goodness,
Now for our dogs we use Advantage (I think). Its from the Vets office. Its very expensive,however.
I think it also has something to do with the seasons. Some seasons here people complain about having a severe flea problems. Some seasons we have lots of ants. One year we had a major problem with spiders. Then we didn't really have problems with them for a while.
I certainly hope you find a solution for the fleas. There's nothing worse than fleas because they like to bite me as well. I'm a 'big girl' & the fleas will be like forget the dogs & the cats, "we can get a lot of meals off of her".
If you find something that works let me know.
I did hear that if you put epsom salt in the yard that it will dehydrate the fleas, so its good for preventing fleas. I'm told to also put it around the areas that the animals are at,sofas,bedding,etc. I haven't tried that one.
I also heard about a product called "7 dust". Put in yard. Can be found at feed & grain stores, county co-ops, some Walmarts. I'm told to be careful cause it comes in 2 different strengths. One of them is too strong to be around people/pets.
good luck
