I used to do pest control for many years and I seen this more often then not when new pets are introduced into a home...

Even had issues with offices that had crawl spaces underneath. Raccoons or other critters would live under the building and fleas would be everywhere...


Internal Parasites I didn't deal with. But Fleas I did.... And I never had an issue at my home after dealing with fleas at a customers place of business or home. Lucky I guess.....
