What is the difference between a cat flea and a dog flea? The previous owners of our house had both cats and a dog and the house is infested.  Will the cat fleas naturally die off with no cats around?  Do we only have to worry about the dog flea population or can they both survive off dogs/humans? We’re currently treating our dog but I always question if its working.  We also have had the house sprayed by a professional and have been vacuuming everyday.  Would it be beneficial to send our dog to my parents and never let her in the house until we know the flea problem is over?

Here’s a page written about the differences between dog and cat fleas. The most common type of flea that infests pets (dogs and cats) is the cat flea (Ctenocephalides felis). The dog flea (Ctenocephalides canis) is second most common. Regardless, flea treatments will work just as effectively on difference species.

If your dog is treated, then allowing her to stay can actually help speed up the eradication process. Fleas emerge from cocoons when they detect heat and pressure. When the dog travels around the home, it will cause the fleas to emerge and jump onto her. The fleas will then die when exposed to your treated dog. This can help kill the fleas that may otherwise enter into a quiescent (dormant-like state) for up to 5 months while they wait to detect a host.

I hope this helps, and I apologize that I took so long to respond.
