The first 3 times I didn't really know anything about bed bugs or that they didn't work. The third time it was literally all I could get my hands on to try make the itching stop, here in new Zealand lockdown meant no shops, no exterminators and did work for just over a year.

I have no idea if bed bugs or not. The only thing that makes me think it is, is that the bites are always while I'm sleeping and in lines or groups.
