PIC Outdoor Mosquito Repelling Coils, 10-piece

I've been using these, or similar ones, since I was 15 years old. I'm 61 now. They weren't always made by PIC either. OFF used to make some too. Anyway, these work great! We have neighbors who have water problems and standing water in their backyard and they won't do anything about it. So we had to do something because we didn't want to catch West Nile. We initially bought PIC's faux Terra-cottta burner combo pack and we bought these as refills for that. I use these in conjunction with a bug zapper light. We have a very nice backyard and love to spend time enjoying it .....without the mosquitoes!! Walmart stops carrying these around mid August so we had to order them online. They usually have these in the seasonal garden section of the store, but they really should keep these stocked year round in their camping section along with all the other bug repellents behind the glass there.
