Itchy red spots on us
If there’s a home infestation, fleas will sense us humans as a potential host and hatch out from carpets, cracks in the flooring and furnishings (find out below how they get there) to try us out for a feed before realising they’ve nipped the wrong ‘host’. Fleas don’t live on humans, but will give us a good bite to check us out first. These bites are recognisable as itchy red spots, particularly around the ankles in the case of a home infestation.
