I've been noticing itchy bug bites on my legs. Usually they are scattered randomly on my legs or arms. But once there were 4 in a row. How do I know if these are from bed bugs or from mosquitoes? They are itchy and red and swollen. I've never seen a bed bug in my bedroom.
if they are bed bugs, how can I find out where they are hiding and how can I get rid of them without having to call an exterminator?
