This isn't a plug and isn't my company - I get nothing outta recommending this but...
there's a soap that has almost no scent but works - I use it a lot this time of year and even use it on my kids (ages 2 & 5). It's all-natural and really helps - HONEST!

Look for BUG BAR - it works!
(You might find it at some of the health food stores, too - they are often at craft fairs and you can get it there...)
