Yikes! glad I am in the UK, we dont have a mosquite problem. but we do have "midges" boy do they love me, they are always attracted to my white hair!! my scalp is a mass of swollen lumps, my legs are covered in bites, and the itch drives me mad! We also have bats which fly around the garden in the evening, I like to sit and watch them, hence the midgey bites. They are protected in the UK and you are not allowed to kill bats of any sort. Luckily we dont have any living in the attic. I Never use repellent as I am not happy about spraying myself with chemicals....hey ho country life.
