How long does it typically take for bug bites to appear?

Question

I was bitten recently, but I can't figure out when since I haven't been outside for hours now and it's night. I thought it was mosquitoes, but it no longer itches, and I have been here two weeks without a single mark. I only need to know this because I'm trying to figure out if the insect is within my room or not, plus I freak out when it comes to bugs.

Answer 1

The bite usually appears within seconds with the usual itching and some slight swelling. Chances are the insect which bit you isn't hanging around for a second helping.
