Mosquito repellent on the legs does really help while it's at its worst. The powdery spray one is least irritating to the skin. (We had one room really badly hit one year and we had to use that stuff just to go in there to treat the rug and vacuum it.)
SQUEAM ALERT ON Now here's something really nasty to consider. Some flea treatments for pets is meant to repel, not kill. Yet one of the most definite flea attractants is our dearly-beloved pets. Some people use Capstar THAT way-- I know it's hard to think of deliberately letting the little darlings missed by our vacuums have a hearty last meal, but they ARE going to jump on Fido and Fluffy no matter what, as one works toward eliminating the problem. This is not an endorsement-- but some people DO use Capstar-type products that way and it can move the elimination project along more quickly (for everyone's good). SQUEAM ALERT OFF
BTW, putting a lot of chem in the living environment can tax an already-compromised immune system.... the more is put into the air, the longer such a person needs to be NOT in the environs, and the more thoroughly the airing should be, after the product has "settled." Also, going barefoot in a treated house (for quite some time after treatment) is asking for a big exposure. Us, we just yanked the carpeting. Something to think about. It's easier to send a rug out to be bombed than to have it bombed in the house, and an area rug can go padless and be treated on the reverse side, where wall-to-wall leaves the padding and underside untreated.
