Natural Flea Repellent??

Didn't know where to post this, but anyone have a natural flea repellent recipe? Like a spray or something I could do immediately.

I think there are some on our bed (we sleep on the floor since we have an oddly shaped room with no room for an actual bed) and my feet and legs are itchy 😫 ...but strangely my husband doesn't seem to be affected by them... hmm... 😑🤔

But anyway, perfume works on ants, but apparently, not so much on fleas.

We're definitely going to wash our blankets and sheets, but I'm pretty sure they'll still come back since we have dogs and a patch of dirt in the front yard. Our chihuahua sleeps in our room but not close to us. She doesn't get fleas that much.

So maybe something for our bed and something for our chihuahua, for prevention would be nice for now. I'd be grateful 🙃

***Btw, we don't have carpet, just some blankets we lay on top of each other. (Pretty comfy, actually 😋)
