Entomology (Study of Bugs)/Unknown Bug
I have some small bugs that I am finding crawling around my bathroom floor. They seem to prefer the dark as they hide under things. They can jump 1-2 inches along the ground and are themselves just over 1 mm. Apparently they are covered with tiny hairs. I took some microscope images and accidentally squashed it a little bit...oh and yes they are very easy to squash and then leave behind a gray mush when squashed. If these images aren't enough I can try and drown another one tonight(they DO NOT sit still) and get more images tomorrow. Also they flee to the baseboards when I start squashing them with my fingertip.
Hard to tell from the photos, but they look like fleas. Do you have a dog or cat? You can catch a few in a ziplock bag and take them to a licensed pest control operator. You can also spritz them with hairspray or deodorant to catch them, unsquished.
