How do I get rid of fleas for good?

Are you sure the fleas are coming for your dog? We had a flea problem a few years back (we don't even have a pet!) and I eventually realized they were coming in on mice :C Make sure you don't have any issues with rodest/other animals that might bring fleas in.

If you are anything like me, just thinking about fleas make me itch!

Even if you miss a few eggs or larva here or there when you clean the fleas won't survive if they don't have anything to feed off of. They'll enter their cocoon stage but they won't come out if there's no host for them to feed from like your dog, so if your house is spick and span and your dog has been thoroughly flea treated, any leftover fleas won't have much hope of survival

Ok. I know that you have seen all the comments, so I'm going to add something that hasn't been mentioned.... D.E. go to the Tractor supply store and get 100℅ decadamus Earth. Get a good face mask and a circular fan.. With the fan blowing, sprinkle the D.E. so it spreads across the area. Do this in sections of your house/apartment. It will put a fine dust on everything! But it kills all stages of a fleas life cycle... Leave on for 25/48 hours. Then dust and vacuum. This is what worked for me after I cleaned/steamed everything. I hope this helps.

I believe I have fleas on me I can feel them in my scalp eyelashes and arms. Can I wash myself with Dawn detergent or apple cider vinegar

I have the same problem

I assume you've done this already but if not, start with a DEEP clean, and of your entire house - not just the couch or anywhere the dog goes (but ESPECIALLY those places). Get a strong vacuum and get in ALLLLL the nooks and crannies to pick up any eggs/larva that might be hiding there. Then wash EVERYTHING--the carpets, the upholstry, the couch covers, all your blankets, even things you think the fleas aren't in--with HOT water and soap. Steam your carpets. Dry your laundry on high heat. Get those buggers out of there. If you're using a flea treatment for your dog you shouldn't really need to resort to insecticide, but it's an option if things are severe enough. But if they're coming in the house on your dog you may need to chase them out of your yard. You can usually do this just by mowing regularly (and makking sure to hit shady hidden spots) and scatter cedar chips in any shady spots where your dog likes to hang out because fleas hate the smell.
