Homemade Flea Repellent
You can make an effective flea repellent from lemon by cutting it into quarters and immersing it in boiling water. This is then steeped overnight to get you the repellent. By spraying this all over your pet, especially behind the ears and generally around the head, and also at the base of the tail and the 'armpits', you can rid it of fleas.
I am wondering if Grapefruit boiled in pieces in water and then steeped overnight would do the same thing...probably would.
Also as a note...dawn baths, baby shampoo and peroxide mixed together baths, and dove baths afterward are great for killing fleas, and the dove washing makes the skin feel better if it is dry.
My dog had fleas when she was four months old, and I didn't feel comfortable using flea medication on her because she was too small for store bought medication, and the stuff from the vet was too expensive. I read that there's something about lemons or lemon juice that repells fleas. I cut some lemons into quarters, and covered them with boiling water. I let the water sit overnight, and in the morning poured it into a spray bottle. I sprayed her several times a day with the lemon water, and also put some crushed garlic into her food. The fleas were gone in no time, and since lemons and garlic only cost a couple of dollars, I saved lots of money!
