Neem Oil - stinky but effective

I had read that neem oil really smells bad -- somewhere between rotting garlic and sulfur.  But it's also supposed to be great for your skin and an effective bug repellent.  So I bought some.  It really does smell somewhere between rotting garlic and sulfur.  But it also really does repel mosquitoes.  You dilute it down quite a bit when you make the repellent and you can add essential oils like lemon eucalyptus and citronella to help drown out that lingering rotten garlic smell.  But when you watch mosquitoes still bite after you've sprayed yourself with deet, of all things, and then watch them just fly around but NOT bite you after you've slathered yourself with a neem repellent, the somewhat odorous smell seems not so bad afterall.
