The most effective thing is to contact a vet about getting flea medications on-board. There are both fast-acting flea meds meant for killing a lot of fleas at once, and long-lasting flea meds that will continue killing any new fleas that might hatch. Baths with mild dishsoap can be a good option for dealing with the worst of an infestation, but won't provide any lasting protection and may dry out a dog's skin if you do it repeatedly.
Eggs can drop off and stay in the environment, so also be really good about vacuuming daily for the next couple weeks, especially in cracks and crevices in any room he's been in, and washing his bedding regularly on high heat. It's better to be overly cautious than risk the house becoming infested for sure.
