I see these very tiny bugs on my walls at home. They are so small that it is very hard to notice unless you are extremely close to the wall and focus at a point. I was able to take a few photos.
These are some close-up photos:
This is how small they look from half a foot distance where it's hardly noticeable:
This is the stain I saw when I squashed them:
Some other things I noticed:
The photos I have shown are the biggest size I have seen so far so I am guessing these are the adult ones. All other ones are even smaller than this where they look like tiny speak of dust.
The extremely small ones jump when I try to squash them, where as the bigger ones like the photos above do not jump. They just crawl.
I do not have pets at home, but I have had guests who stayed at home who has cats at their home.
When I sleep at night and wake up, I see bits all over my back that looks like hives and I suspect if this insect might be causing it.
I only found this inside my home (apartment) walls.
Does anyone has any idea what this might be?
