Kill Bed Bugs
The common bedbug (Cimex lectularius) is the best adapted to human environments.
They can get into your house by crawling in the spaces in between walls which is where they live also.
Nobody likes them. They crawl out just before dawn and bite you, sucking out blood for about five minutes. You don’t feel anything until after the bed bug is already safely back in its home. I suggest you get some bed bugs spray and get rid of those tiny pests.
