Very tiny insects. are these first stage bedbugs? They’re probably 1 mm. The smaller ones look more like ants to me the next stage is covered with white diatomaceous powder so it might be hard to tell what it is but it’s also very small maybe 1.5 mm
Here’s a better picture of these are really tiny the tiny ants that are under a millimeter and these tiny bugs that are under a millimeter came after I found a bedbug infestation in my house they were found in and near a sink that I had laced with diatomaceous powder around it￼
really hard to say, but some look like ants in some of the pictures. The others are too hard to say.
