I'm one of those who folks love to have at their outdoor BBQ. Nobody's bothered by mosquitoes while I'm around, but I'm surrounded by clouds of the little pests. My son's inherited it, whatever "it" is.
I heard about the Liquid Joy thing via an e-mail, and thought, I've gotta try that, but then I received another e-mail:
Joy of the Great Outdoors
So I never tried it.
The mosquitoes are baaaaad here now, 'cause we had a lot of rain in the spring, and we have a new city entomologist who doesn't believe in spraying. He has another plan.
