Tiny Black Bugs That Look Like Poppy Seeds

Do they move?

Half the answers here are alive and half are not, and that is the fastest split available. People describe both as bugs because both look like scattered seeds.

• Moving, in a wardrobe or under furniture — carpet beetle larvae.
• Moving, pale-ish, in damp paper or around a window — booklice.
• Not moving, on pet bedding or where an animal sleeps — flea dirt.
• Not moving, in a bathroom or near a drain — drain fly pupae or debris.
• Moving and jumping — springtails, which need damp rather than treatment.

• Carpet Beetle. Not smooth like a seed close up — carrot-shaped, banded and bristly, and they leave shed skins behind that look like more of them.
• Flea dirt. The decisive test: put some on wet white tissue. Flea dirt is digested blood and bleeds rust-red. Nothing else on this list does.
• Booklice. Soft, pale grey, under 2 mm, in damp paper or around window frames. They crush to nothing rather than feeling hard.
• Spider Beetle. Glossy and rounded like a seed at a glance, but with visible long legs and antennae once magnified. Comes from old dry food.

If you still can’t tell

Do the tissue test first — it takes ten seconds and it is the only check here that gives a definite answer. Wet a piece of white tissue, press it onto the specks, and look for rust-red smears. Red means flea dirt, which means fleas, which means treating the animal and the home rather than hunting a beetle. No colour change means you have an insect, and then the room tells you which one.

Common questions

Or just photograph it

If none of these fit, the identifier will take a photo and give you a species, a danger verdict and what it is commonly mistaken for. It says when a photograph cannot settle something rather than guessing — what it can and can’t do.
