This is creeping me out.
I got into a bunch of seed ticks once, and really bad chiggers on a job site. Nothing like having to go back day after day knowing what will bite you. I used some kind of really strong bug repellent. It worked but I still can't say words with the letter R in them.
I know it's not a bed bug story but it is the best I got.
Have you ever used diatomaceous earth as a preventive bug killer ? It is cheep harmless to humans but works on anything with an exoskeleton. You an even eat it, it is in every grain product made in the US.
