Hi,

I moved in to my a new house construction and it has been about a year. All of a sudden I have been finding these small brownish beetles under my sink in the bathroom, and they are about 3-4mm long. They just suddenly started showing up around mid September, and I live in Southwest of the USA. I haven't seen them in the kitchen or anywhere else in the house. I appreciate anyone's input, and thank you.

It's Tribolium confusum (Confused Flour Beetle), or a very similar, related species -

Very common and found worldwide, and can be a nuisance if they become numerous. They feed on dried, stored food products such as flour and cereal.
