Here are some factors for why bugs love you some much:

1. Alcohol — just one bottle of beer can increase your appeal to the nasty bugs.

2. Pregnancy — as if pregnant women don’t have enough to worry about, they get bitten about twice as much as the rest of us. The body temperature of pregnant women is a degree warmer than everyone else, and they exhale 21 percent more carbon dioxide.

3. Bloody type — Type O blood types are bitten twice as much as Type A. Type B is somewhere in the middle.

4. Exercise — Working out builds up lactic acid in your sweat, making you a little more tasty.

**By no means stop exercising or getting pregnant so lets get some good repellant. We need to avoid the nasty chemicals in most bug sprays by getting resourceful and making our own.

Ingredients:

Essential oils: choose from Citronella, Clove, Lemongrass, Rosemary, Tea Tree, Cajeput, Eucalyptus, Cedar, Catnip, Lavender, Mint
Natural Witch Hazel
Distilled or boiled Water
Vegetable glycerin (optional)

How to Make Homemade Bug Spray:

Fill spray bottle (I used 8 ounce) 1/2 full with distilled or boiled water
Add witch hazel to fill almost to the top
Add 1/2 tsp vegetable glycerin if using
Add 30-50 drops of essential oils to desired scent. The more oils you use, the stronger the spray will be. My personal favorite mix is: Rosemary, Clove, Cajeput, Lavender, Cinnamon and Eucalyptus… it works great and smells good too!
