Bunkmoreland, sorry you are incorrect, fleas from wildlife is not a problem here, the problem arose from the pets that lived in the property. When I was in pest control, 50% of all the flea problems I encountered we from people moving into a house that previously had fleas and had been empty for a while or it was people returning from holiday. Poor fleas were starving and would bite anybody they came across. The best treatments are only available to qualified pest controllers, and even they often have problems with flea infestations, that is why I suggest a guaranteed treat treatment.
