Unfortunately fleas only hop on the body of your pet when they want to feed, then they hop off again and stay in your pet's environment. So you need to treat all pets in the household as well as the environment (which contains the fleas, their eggs and larvae). Flea treatment:  1) Get some flea medication such as a Flea spray or a spot on from a pet shop or your veterinarian and apply monthly(apparently you are already doing that) 2) get flea powder, put some in your vacuum cleaner bag and vacuum your house and furniture and also non-carpeted areas frequently to remove flea larvae and eggs which live off house dust., Dispose of the bag in the trash outside. Hot-wash all the pet's bedding, If you do this diligently for a few months you will get rid of the fleas. It also may be a good idea to have Gizmo examined by a veterinarian as this could also be caused by an allergy to something else besides flea bites, a fungal or bacterial infection.
