Insect bites on my face, what gives?

This has been happening to me since summer! I keep getting bumps on my face that look like insect bites. I thought they were from mosquitoes, bed bugs or dust mites but I clean my room every day and rarely open the windows.

It only happened to me THIS summer! (I'm living in a rather humid place) What gives? I didn't move or change any of my routines, except stayed at home a bit more often
