Question QUESTION: My son's room has these on the floor, not a lot, we thought it was just lint or dirt at first. They've showed up over the last few weeks. We'd vacuum and they would return. No bites, mattress is clean. They are odd shapes and sizes. Some are kind of translucent. Any ideas.
Answer They do look like scabs/dried blood. Are they concentrated in one area or scattered around the room? Do you have a pet that has access to this room? My guess is they are being scratched off something or someone. Sorry I can't be more specific.
I can answer questions in any area of entomology (study of insects, spiders, mites, ticks, and other terrestrial arthropods). Contact me about home and garden insects, insects that bite and sting, and insects that damage homes such as carpenter ants and termites.
