The bugs here are the biggest pain. I don't like using chemicals but make sure you spray around the outside of your home. I know EcoSmart makes a botanical spray but you need to spray it often.
Sounds like you are getting bit by deer flies, they hurt like all heck and they itch like crazy (sometimes they open with clear pus, sorry tmi).
Pick up some tea tree oil, lavender oil and peppermint oil. Mix a few drops of each in a small spray bottle with water (2 to 3 oz of water). Spray this on you when ever you are outside, you can also spray your home (inside and out), your clothes, hair, children and pets. You can also add some tea tree oil to your body wash and shampoo.
I am in the country so I know how annoying the bugs are. You may also want to invest in some type of screen enclosure so you can enjoy the outside without getting bit. If you use garlic, its the smelly part of it that keep the bugs away. So its better to eat foods with it then to take pills.
Almost forgot the tea tree oil helps with the itching or an oatmeal bath.
