Feed the dogs/cats fresh garlic.
2-3 cloves a day, everyday.
After a couple of days, they will develop a kind of natural oil on the surface of their skin which fleas hate, and will drop off/go away.
Keep feeding them that till you are sure that your house is flea-free.
Only downside to this is when your dog pants on your face....it's reallyyyyy stinky.
How we managed to get them to eat fresh garlic cloves is force open their mouth, then close it with both our hands...after a few seconds, they will be swallowed lol.
