Mozzie Coil Quest

Why is it getting harder to find mozzie coils? Anybody know? I use mozzie coils every summer because I don't have flyscreens, plus I like the smell. Recently I asked a checkout dude at my local minimarket why they didn't stock mozzie coils any more. He shrugged his shoulders and said he didn't know, but they didn't stock them any more. Today I rode my bike to a mini market further away, where I found them last time, but this time there were none. What the hell is going on? I spent about ten minutes looking at the fly/cockroach/mozzie section and it seemed that everything is now geared towards flys and cockroaches. They did have Aerogard but I don't want that. You have to spray that on yourself, and I'll be damned if I'm going to bed covered in Aerogard.
So, tomorrow the search for another mozzie coil dealer continues.

Thanks for listening.
