There are lots of this bug appearing in our cabinets. They appear to be living in the particle board of the cabinet structure. We've wiped them all out with diluted alcohol but they come back. We live in Kaohsiung, Taiwan. 

EDIT: Here's hopefully a better pic. Although zoomed out, it's a little clearer. There are lots of these little guys climbing around in the pantry.

I've edited in some pictures that may be a bit better. 

Try zooming and using flash next time you see a very small Insect. What phone do you have?

I know right? The little guys are so small it's hard to get the camera to focus on them. Mostly we just know what they DON'T look like.
