Do fleas stay around the house when your dog is not around the house or do they leave because there is no dog around the house or do they stay because they just want to stay or do they stay hoping the?

If the dogs have fleas, irregardless fleas are in the house. Fleas do not care, as long as they have a warm enviroment, use flea medications on your pets if you live in a flea area like the northeast, you can get a bad flea problem in your home if you are not using frontline plus etc on your dog, once you get fleas binging on and off you, its time to fumegate your home, you can buys cans of spray to do this, but first you must clear the home of children and pets, close all Windows, set off the cans of spray and leave the house, you can not re enter for about 8 hours. This usually kills all bugs in the house. use a flea med on your pet to prevent all of this
