Every summer I get attacked by these bugs when I walk outside... they are shaped like footballs (pointed ends), and are yellow-ish brown. They blend into my summer tan so I feel a bite and have to analyze my arm to find the stupid things. I don't get raised bumps from the bites, they just hurt like the dickens! And I don't think they're chiggers - chiggers are supposedly red.
Do you know what bug this is? And how to get rid of/decrease the numbers?
