Mosquito knockout

I have been getting bitten by things lately. They have been taken months to fully heal. I have been seeing black midges and this mosquito in the store. Only reason I caught it? I saw something flying towards me and I hit it with a paint brush. A coworker told me to take garlic pills because I seem to attact them and I'm tired of being itchy. We needed the rain desperately, but I noticed a higher number of different fly species I don't usually see.
