Extension ServiceIs this a bot fly larvae?
I found a cuterebra larva on my bathroom floor today. Freaky! So after watching them get pulled out of cats' noses they have my full attention! I have two cats and a dog that don't show any symptoms. Did it fall out of my boot? A hand truck delivery service? We had kids sledding, did they drag it up off the ground while sledding? Would I know it if I or my kids were living hosts?
It is hard to say where the larva you found came from, and I agree it does look like cuterebra. Closer examination is needed to confirm. These larva typically fall/crawl out of the breathing hole in the skin of the animal that harbored it, so it obviously originated in an animal, but I don't know how it ended up on your bathroom floor.
It is not impossible for humans to get infected, but it is quite rare. To become infected, the fly (adult form) would have had to lay eggs in or near a wound.
