Fleas can transfer from one house to another if they hitch a ride on a person, pet, or object that carries the fleas. Fleas can attach themselves to shoes, clothing, luggage, or any other item that has been in contact with an infested area and then be transported to a new location. Fleas cannot fly, but they are excellent jumpers and can jump up to 7 inches vertically and 13 inches horizontally. This means that they can easily jump from one host to another or from an infested carpet to a person's pant leg. If you are moving to a new house, it's important to take steps to prevent the transfer of fleas. You can do this by treating your pets for fleas before moving, washing all clothing and bedding in hot water, and inspecting your belongings for fleas or flea dirt.
