Having been through it, I can assure you that bed bug bites are well beyond ant bites. They are downright nasty.Pain of equivalent of ant bite (or less ) never occurred to me
My wife and I arrived in Florida in mid January that year, and I grilled dinner the first few nights we were there. I awoke on about the 3rd day with pronounced welts that were extremely itchy. I assumed some sort of super mosquito had nailed me while I was sitting outside, grilling in the dark of night. But I had never seen anything like those bites, and the painful itch was no joke.
I got some bug spray for the time outside grilling. Things got worse. Most interesting to me was that some of the bites formed a line, usually of about 4 bites, one after the other. A day or so later I was walking past a mirror and I noticed a small brown bug walking across my chest. I was able to capture it and examine it. I also visited a website that identified bite marks. The specimen and the bite mark website confirmed the bed bug diagnosis. The series of bites in a row is a tell-tale sign. They apparently eat, take a nap, wake up, move over a little, have another meal, take a nap, move over, etc.
What was also interesting was that for at least the first few days, my wife did not get bitten. That is what made us think I was being attacked while outside grilling. I was actually being attacked in my sleep. Evidently they prefer some food sources to others, and my sweeter taste saved her for a while.
Killing them all was a major effort. My landlord made the mistake of thinking he could do it himself with a bug bomb, but that barely touched them. He had to hire professionals, and they had to clear the condo of anything that could be damaged by heat (electronics, etc.) and use big heaters to turn the condo into a bug oven. The badly infested furniture had to be thrown away. We also had to wash all our clothes and dry them at high heat.
Once they were gone, though, they were truly gone. No reason to worry any more.
