Hi K.! We use a repellant by Jason called Quit Buggin' Me. You can find it at health food stores or online. It's very mild but it works!
Also, I have heard that baking soda works well for big bug bites.
I see you had a suggestion for using dryer sheets for repellant, but dryer sheets are filled with chemicals. I have heard that rubbing basil leaves on the skin works well.
I hope you have a wonderful, bug free summer!
