I keep getting bites on my feet, ankles, calves at work and so do a few others in my area, but mine is the worst. I don t see any mosquitos or any other bugs, but the carpet is very dark with patterns so might not be able to see small bugs very well. What do you think it might be? I am getting very freaked out because I can t see anything and all of a sudden I just got another 3 bites on my ankle. Any ideas? They look like mosquito bites more than anything but again, I don t see or hear any mosquitos. ????
