I found this on Yahoo Answers. It seems to be the best answer at the moment. Where is discuss your house you can extrapolate the info to the dog house. [quote=Yahoo Answers]First of all, you need to purchase a good flea control product like Frontline Plus, Advantage, Vectra, or Comfortis. Anything that you can get a pet store that has pyrethrines/permethrines as the main ingredient won't work. This includes ALL flea shampoos and collars. Once you've treated ALL the animals in the house with a good flea control, you need to treat your house. Fleas don't actually live on your animals. They take blood meals off of your animals and then burrow back down in the soft surfaces of your house. Buy an area treatment spray like Siphotrol Plus II and treat all of your carpet and furniture (including beds and couches.) Don't use bug bombs for this as they don't penetrate down into the soft surfaces very well. Wash ALL of your bedding and anything that your animals come into contact with in HOT water to kill the flea larvae. After you've done all of this, you'll need to vacuum your house daily. After you vacuum, make sure you empty the bag/canister OUTSIDE. If you empty it inside, you'll just be moving fleas around. Due to the life cycle of the flea, it can take over 3 months to get rid of a flea infestation, so you'll need to continue to do these things for at least that much time. MAKE SURE you apply good flea control on all of your animals throughout this process and any time the temperature is above 40 degrees Fahrenheit and over 40% humidity. Hope this helped!
