Hi Aussie, that'd be weird. Lucky they're not bees or wasps or some stinging insect. There's an 'old wives tale' up my way that if you take B vitamins it'll keep the mozzies away. I've also heard another tale about bugs being attracted to people who have diabetes. No idea if there's any truth in the last one, but I think the B vitamins do keep the mozzies away. Maybe it's a perfume you wear or an ingredient in one of your toiletries that attracts them at this time of year or something like that???
