Hi! We only winter in Florida, but the bugs in the heat of a central Illinois summer are just as bad! My research said that it depends on your body aroma - (not sure what to think of that...whether I'm disgusting or delectable,) and even whether you're stressed or not. (If you're low-stress, you don't emit a chemical that wards the bugs off.) Who knew that being even-keel and happy could be a detriment! Thanks for reading! I woke up in the middle of the night, my brain landing on a piece for your pub. Hope to get it to you this week.
