First of all, what part of your leg is that? LOL
It looks like your typical mosquito bites to me.
Chiggers are smaller and closer together, tho I cannot quite get the scale from your... whatever that is. Bedbugs, I dunno, but you can look for them in the crease near the edge of your mattress- and that's gross. They are tiny and bunch up there in the day.
Get some cortisone cream for your itchiness. Denver People, I swear.
