Hi Nell, It's just been a super rotten flea season. I've never had to deal with fleas and this past fall my dog brought them in. My ferrets had them too and it took us a while to break the cycle. We had to throw out the beloved carpet covered ferret condo. We use revolution on the ferrets and dog, Advantage on the couch vultures (cats). I've had to vacuum like a mad woman (put a flea collar in the vacuum bag) and sprayed the couches weekly (a bit neurotic I was). But we are flea free. About 16 years ago when I rescued my horse she came off the trailer with fleas, so it is very possible. Thankfully a good soak in a flea shampoo really did help and was the last we saw of that situation. Have your friend look for a fly/mosquito spray that also kills/prevents fleas, I'm pretty sure there are some brands out there. Erin [Posted in FML 7364]
