I’min south texas here and recently over the past 10 years, Texas has been infiltrated with exican Bed bugs. They are traveling on birds. They are not like the other bed bugs. http://neurosci.arizona.edu/kissingbugs/basicfacts at this link, there is a picture and some info. They do not seem to feed every night but very randomly as we see them in spurts here. They do not hide in the bed, but usually behind or under baseboards where it is dark, but they are attracted to light at night. They bite once maybe twice and bite where you are the warmest. If your body temperature is hotter than the others at your home, then you will be the only one afflicted. We have lots of pets and chickens and wildlife here, so when I asked our pest guy what to do about them, his responce was….. don’t let them get in your house. Uh, thanks man, didn’t know to do that! Geez….he said regular bug/flea killers would work, but I caught one and put it in a zip bag and experimented to find what killed it. The only thing I had in the house that killed it was my shoe! wasp spray, flea spray, roach/ant spray didn’t do a thing. I then added clorox, borax, peroxide, salt, and nothing. So we do the best we can here and have been lucky not to get any inside that we know of. Best of luck.
