my freind and her family just bought a home and the yard had been dry for so long there were strays living under it so the yard tended to have millions of fleas.she has tried lyme and soaking the yard. can anyone suggest something inexpensive to get rid of them. she had the gas man come to her home to fix a leak and he ran from the backyard to his truck spraying himself all over due to the millions of fleas in the back and threatend to report her, but she is trying to find something, whereas she has never dealt with this she doesnt even have a pet. she has three children whom one had to be rushed to the hospital for an allergic reaction from the bites. and the kids are very young so now they cant even enjoy the outside until this is resolved. so can anyone help me to help her thank you.
